Chapter 1
About this release
•
This release includes updates to the ECLIPSE simulators (ECLIPSE and ECLIPSE
FrontSim) and pre- and post-processors including ECLIPSE Office, Schedule and PVTi.
•
SIS reminds customers that we are working towards the retirement of the interactive
products, and their replacement by Petrel Reservoir Engineering. Customers are strongly
advised to consult their SIS Account Manager about the transition to Petrel RE. Note that
Petrel RE includes access to some of the interactive products (ECLIPSE Office, Schedule,
FloGrid, FloViz and GRAF) under the Petrel license.
•
MEPO is a multiple realization optimization framework which submits and controls
reservoir simulation models. Reservoir engineers can use this to optimize and semiautomate their simulation workflows. The most common applications are assisted history
matching, uncertainty analysis, sensitivity studies and optimizing field development plans.
MEPO 4.2 is available on the ECLIPSE installer via the Install Products page (insert the
DVD and click on Install Products). To view MEPO documentation use the Browse CD
option on the ECLIPSE installer.
•
ECLIPSE 2013.1 is supplied with ECLRUN 2013 Update 1.
Warning
ECLIPSE 2013.1 will be the last major release of ECLIPSE that will be
compatible with license servers based on the Solaris operating system. Future
versions of ECLIPSE will require the use of the slbsls daemon, which is not
available on Solaris. Clients will need to make appropriate provisions to have
license servers based on Windows or Linux to run future versions of
ECLIPSE.
Warning
ECLIPSE 2013.1 will be the last major release of ECLIPSE to support the
Linux PPC 64 platform, also referred to as IBM Power series. ECLIPSE

About this release
ECLIPSE Suite Release Notes
ECLIPSE and FrontSim developments
ECLIPSE 2013.1
This is a major release of the ECLIPSE suite of simulators and extends the functionality of both
ECLIPSE 100 and ECLIPSE 300 in a number of key areas. The developments are summarized
in this section and more detailed information is provided in "ECLIPSE 2013.1" on page 16.
Modeling of chemical EOR processes
•
The ECLIPSE 100 Polymer option has been extended to facilitate the modeling of
advanced polymers and gels, including temperature sensitive “popping” polymers.
•
The ECLIPSE 100 Polymer option now gives more robust modeling of shear effects on
polymer rheology.
•
A surfactant model has been added to ECLIPSE 300. This models surfactant effects on
miscibility, surfactant adsorption onto the rock and wetting effects resulting from adsorbed
surfactant. This model may be used together with the existing compositional foam model
implemented in ECLIPSE 300.
The simulation of unconventional reserves
•
The ECLIPSE 100 Coal Bed Methane option Palmer-Mansoori rock compaction model has
been extended to aid the diagnosis and robust solution of “rebound regions”.
•
ECLIPSE 100 and ECLIPSE 300 have been extended to allow for improved modeling of
hydraulic fracturing through the use of directional, hysteretic rock compaction data tables.
This may now be applied to both transmissibilities and dual porosity sigma multipliers.
Compositional fluid modeling
•
The range of available equilibrium deviation models in ECLIPSE 300 has been extended.
WAG hysteresis
•
WAG hysteresis modeling facilities have been extended to allow two-phase and threephase water saturation regions to be defined to enable the co-existence of conventional and
WAG hysteresis saturation functions.
Well modeling
•
The ECLIPSE 100 and ECLIPSE 300 Multi-segment Well Model has been extended to
allow a number of devices such as valves and ICDs to close completely, isolating branches
of the well. The isolated branch will continue to model cross-flow.
Thermal
•
A number of changes have been made to the JALS solver to improve the robustness of
thermal simulation.

Other developments
In addition, the release continues to develop integrated workflows with Petrel RE.
FrontSim 2013.1
FrontSim 2013.1 is a major release of the streamline simulator. The emphasis in this release has
been on both usability and extending the functionality. The developments are summarized in
this section and more detailed information is provided in "FrontSim 2013.1" on page 42.
Saturation functions
JFUNCR activates the Leverett J-Function option to scale capillary pressure according to rock
porosity and permeability on a per saturation region basis.
Water flood management
New functionality has been added to allocate solvent among a set of injectors defined by the
user. This functionality is managed by the new keyword WCONPATS. It is described in the new
section "Solvent Pattern Flood Management - Solvent allocation" in the "Solvent Model"
chapter in the "FrontSim Technical Description". There is also a description of the WCONPATS
keyword in the "FrontSim User Guide". In addition, a number of pattern-based summary vectors
are available to support the solvent allocation algorithm.
Reporting
A new set of SUMMARY output keywords for pattern-based solvent efficiency has been added.
Performance
Following the introduction of the parallel (multi-threaded) Algebraic MultiGrid Solver in the
2012.1 release of FrontSim, the process of setting up the equation system for the pressure solve
has now been fully implemented for parallel processing. This contributes to a reduction in CPU
time.

•
We recommend that, if you are on Xeon systems with Westmere or Nehalem chips, you
upgrade to RHEL 5 Update 5.
•
For Sandy Bridge (E5-26xx) systems, we recommend Redhat 6 Update 3.
•
The InfiniBand drivers that are now tested are the OFED 1.5.4.1 drivers. These need to be
installed and built, and instructions on how to do this are in the "ECLIPSE Suite Installation
Guide". The rpms are provided on the ECLIPSE DVD.
Windows
•
Microsoft Windows 7 64-bit Professional SP1 is supported but we expect that all 64-bit
variants of Windows 7 will function correctly.
•
Microsoft Windows Server 2008 R2 (64-bit) SP1 with HPC pack SP3 and Windows Server
2012 HPC are supported for the simulators only. We have also tested Windows Server 2008
R2 HPC SP4 and this functions correctly as well.
EnginFrame portal for Schlumberger simulation software
An issue has been discovered which will impact users of Petrel Run Management using the
NICE EnginFrame portal for Schlumberger simulation software (EPSSS). The fix to this may
be found in the 3rdparty/EPSSS_patch directory on the ECLIPSE 2013.1 DVD.
Alternatively it may be obtained by contacting your NICE or Schlumberger account manager.
Note that this fix is for the EPSSS, not ECLRUN.

Benchmarks
The new distribution format includes all the benchmarks and utility software. The benchmark
data includes new FrontSim and ECLIPSE 300 benchmarks. These can be found under
ECLIPSE/resources/BENCHMARKS.
Certified platforms
The supported hardware platforms and operating systems can be obtained from the certified
systems letter that accompanies the 2013.1 release. Reference benchmarks are available from
your Account Manager.
Licensing
•
The flex version is 11.8 and the flex daemon for Schlumberger applications is slbsls. It
will serve licenses to Windows or Linux applications. The new version of flex supports
CodeMeter dongles and Petrel licenses can be served from Linux as well as Windows
license servers.
•
From the ECLIPSE 2014.1 release onwards, the old slbfd license daemon will no longer
be supported. The old slbfd daemon has not been the default mechanism of licensing for
ECLIPSE for a number of years and so will be retired. Any clients still using a slbfd style
license will need to request a new style license from their account manager. All licenses
locked to CodeMeter dongles will be the new slbsls license, so no action is needed. If the
license is locked to anything else, then the type of license can be checked by looking at one
of the ECLIPSE INCREMENT lines.
An slbsls license feature (which will work) looks like this:
INCREMENT eclipse slbsls 3013.12 30-nov-2013 1 ……….
A slbfd license feature (which will not work with ECLIPSE 2014.1 or later) looks like this:
INCREMENT eclipse slbfd 3013.12 30-nov-2013 1 ……….
Windows licensing
•
The flexlm tools are no longer distributed on the DVDs. All licensing is now run through
the Schlumberger licensing tool. The macros that used to drive flex are also no longer
available.
•
When running local simulations on Windows through ECLRUN (that is for simulations
launched from Petrel or the Simulation Launcher) the license check is disabled by default
in ECLRUN. Please refer to the ECLRUN User Guide for details on how to enable the
license check. It is recommended that Codemeter dongle drivers are updated to version 4.5.
The latest release can be obtained from either the DVD or the Codemeter web site.
Linux licensing
•
Licensing is supported on platforms using Redhat 5 Update 1 or later.
•
A few changes have been made to the ECLIPSE LSF integration kit. In particular, the
queuing of MR jobs is now supported. Note that you must upgrade LSF to 7 Update 5 for
this to work.
ECLIPSE Suite Release Notes
2013.1 release overview
System and licensing information
11
•
Since the 2007.2 release, ECLIPSE has been compiled to use the slbsls daemon. This
means that you can set the environment variable SLBSLS_LICENSE_FILE or
SLBFD_LICENSE_FILE on Windows to pick up the licenses. Note that we now suggest
that this is set in the USER section rather than the SYSTEM section as these variables are
picked up dynamically. They can also be used on Linux.
Backward compatibility
Schlumberger endeavors to maintain license back compatibility (the ability to run for example
version 2012.1 of ECLIPSE under a 2013.1 license), but this is only guaranteed over a three year
cycle. Clients wishing to run versions that are more than three years old may be required to
dedicate licenses to older versions and run a separate license server for this purpose.

ECLIPSE 2013.1
New facilities
ECLIPSE 100
RUNSPEC section
Coal Bed Methane option
•
CBMOPTS items 4-9 can be used to modify the Palmer-Mansoori rock compaction model
as specified by the ROCKPAMA keyword:
•
Item 4 can be used to activate monitoring of passes through the rebound region (when
the pore volume derivative changes sign), enabling the output of the number of passes
through the rebound region using mnemonic NPMREB in RPTSCHED or RPTRST.
•
Item 5 can be used to select a different modeling of the volumetric strain term of the
Palmer-Mansoori model. For cases where the sorption diffusion process is slow, the
instant adsorption assumption of the strain term might not be valid. This could result
in a negative total compressibility, and in the limiting case, the reservoir equations
cannot be solved. The coal is swelling/shrinking without the corresponding exchange
of gas. For such cases, the alternative forms enabled by this item should be explored.
•
Item 6 can be used to request a scaling/no-scaling of the Palmer-Mansoori strain term,
by using the same scaling as used for the adsorption capacities. By default scaling is
applied.
•
Item 7 can be used to request that the pore volume and/or the transmissibilities should
be altered by the Palmer-Mansoori model.
•
Item 8 can be used to perform a chop on the pressure if passing through the rebound
pressure (this is for the standard Palmer-Mansoori model). In some cases this can
enhance convergence.
•
Item 9 sets a minimum pore volume for the Palmer-Mansoori modifications of the pore
volumes.
PROPS section

properties to be specified on a cell-by-cell basis.
•
The keywords PLYTRRF and PLYTRRFA have been added to allow adsorbed polymer
residual resistance factors to vary with temperature. If PLYTRRFA is used to make
PLYTRRF a histogram of temperature intervals, the part of the adsorbed polymer
corresponding to a temperature dependent RRF in the nnnth interval of the PLYTRRF table
is viewable as a restart field with the mnemonic CABINnnn, and the value in a given block
can be viewed as a summary vector with the mnemonic BCABnnn.
•
The keywords KRWH, KRWRH, IKRWH and IKRWRH have been added to provide separate
end-point vertical scaling for the two-phase and three-phase WAG hysteresis water relative
permeability saturation functions. These are specified via the WAG hysteresis two-phase
and three-phase saturation region keywords WH2NUM and WH3NUM.
•
The existing keyword ROCKTABH for hysteretic rock compaction data tables now allows
the specification of directional transmissibility multipliers, similar to keyword ROCKTAB,
when RKTRMDIR is also defined.

The new keywords WH2NUM and WH3NUM have been added to provide optional alternative
saturation regions for specifying the WAG hysteresis two-phase and three-phase water
relative permeability saturation functions. This involves some additional saturation table
processing irrespective of whether these keywords are specified or whether the values are
defaulted from the values specified via the SATNUM and IMBNUM keywords. The use of the
new keywords WH2NUM and WH3NUM and the associated additional processing can be
disabled by setting item 201 of the OPTIONS keyword to 1.
•
For the rock compaction model ROCKPAMA, the volumetric strain term is scaled by the
same multiplier as used when evaluating the adsorption capacities. This can be disabled by
using CBMOPTS item 6. Also the derivative modifications of the pre-2013.1 version have
been disabled. See OPTIONS item 200.
•
Modifications have been made to the model initialization process for the case where item

From the 2012.2 version onwards corrections have been made to the assignment of the
saturation end-points from the end-point scaling arrays for two-phase models when the
ENDSCALE keyword has been specified. Prior to the 2012.2 version, in some cases, the
saturation end-points associated with the absent phase were incorrectly defaulted. The pre2012.2 version of this end-point assignment process may be selected by setting item 194 of
the OPTIONS keyword to 1.

modification prevents excessive falls in gas relative permeability which can occur in some
circumstances when the primary drainage curve is used to construct the secondary drainage
cycle. This modified model may be selected by setting item 197 of the OPTIONS keyword

Improvements in the handling of ROCKTAB directional transmissibility multipliers, items
3 – 5 (enabled when RKTRMDIR is specified) alter the update of well connection factors.
From 2013.1, well connection factors are updated during simulation for any wells
completed in the corresponding cells.
•
Further improvements have been made in the handling of ROCKTAB directional
transmissibility multipliers, items 3 – 5 (enabled when RKTRMDIR is specified). From
2013.1, the treatment of NNC transmissibility is altered to take account of known NNC
directions. The pre-2013.1 treatment may be selected by setting item 199 of the OPTIONS
keyword to 1.
•
The ROCKPAMA keyword for the Palmer-Mansoori rock compaction model can now input
a geometric factor to alter the compressibility of the model. The derivatives for the standard
form of the rock compaction model do not alter the derivatives for cases having a negative
compressibility, as was the case for pre-2013.1, but new models are available that can be
used if the standard model should lead to unphysical solutions. The modifications should
be reviewed with the options in CBMOPTS items 4 – 9. In addition it is possible to input
sorption-induced strain terms for the solvent. Also, if the Langmuir adsorption capacities
are scaled, this is reflected in the rock model. See CBMOPTS item 6. The pre-2013.1
calculations can be obtained by using OPTIONS item 200 set to 1.
•
For the 2013.1 version, the reporting of the end-point scaled saturation tables via the
EPSDEBUG and EPSDBGS keywords has been modified. The new behavior extends the
precision of the reported values and includes the additional saturation nodes corresponding
to the critical saturations of the displacing phase. It also includes the alternative saturation
regions for water relative permeability, which are optionally available for the WAG
hysteresis option. The pre-2013.1 version of the scaled saturation tables can be obtained by
setting item 202 of the OPTIONS keyword to 1.
•
When ENDSCALE is specified, the maximum attainable unscaled and scaled oil saturations
used to apply the end-point scaling can be constrained additionally to include connate gas
for two-point scaling by setting item 205 of the OPTIONS keyword to 1. By default,
connate gas is omitted from these calculations.
•
A lower bound of unity is now applied to the multipliers specified in keywords PLYVISCS,
PLYVISCT and PLYVSCST. By setting item 208 of the OPTIONS keyword to 1, the pre2013.1 error checking is applied instead, and this allows any positive value.
SOLUTION section
•
For the 2013.1 version, the checking of input enumerated saturation data has been extended
to check the data values against their expected end-points for end-point data derived both
from saturation tables and end-point scaling arrays and tables. The pre-2013.1 version of
this checking process may be selected by setting item 190 of the OPTIONS keyword to 1
in the SOLUTION section, or sections before it.
•
In a VISAGE restart run, it is now an error if timestepping starts before well completions
have been re-specified, as the well connection factors have not been recomputed. This can
be downgraded to a warning using item 8 of the VISOPTS keyword.

For the 2013.1 version, the flow scaling factor calculation used for inflow control devices,
specified in item 11 of keywords WSEGSICD and WSEGAICD, has been altered to take into
account changes to the well structure that take place after the device has been defined. This
change only effects the calculation when item 11 is set to 2 and there is a choke defined
with the WSEGTABL keyword that is downstream of the inflow control device; all other
flow scaling factor calculations are otherwise unaffected.

For the 2013.1 version, the timestepping selection of the keyword ZIPPY2 has been
modified when close to report steps. Pre-2013.1 behavior can be restored by setting item
193 of the OPTIONS keyword.
•
From the 2013.1 version, keywords WRFT and WRFTPLT have been adjusted to act at the
start of the next period of simulation (for example a DATES or TSTEP keyword). This
allows ECLIPSE to gather all the salient data before generating the RFT file. As the
generation of an RFT file triggers connection order calculations, this may affect cases
where COMPORD is followed by a WRFT or WRFTPLT keyword. In such cases, the pre2013.1 behavior may be recovered by setting COMPORD to give DEPTH, TRACK or INPUT
as necessary, or by setting OPTIONS keyword item 206 to 1.
•
The choke model in the extended network model has been modified so that it now gives
answers similar to the 2011.1 version.
Tracers
•
In models that include the SURFST keyword, the surface tension is interpolated using the
surfactant concentration that is output via the BTCNFSUR summary quantity. This may
affect models in which the surfactant is multi-partitioned between various fluid phases.
•
Models with oil or gas tracers with both VAPOIL and DISGAS run in PARALLEL now
treat NNCs more accurately. Prior to 2013.1, tracer transport by vaporized oil in these cases
was calculated incorrectly. Pre-2013.1 behavior may be recovered by setting OPTIONS
keyword item 207 to 1.

RUNSPEC section
•
For the velocity-dependent relative permeability (VDRP) models selected by item 5 of the
VELDEP keyword, the method of calculation of the three-phase gas and oil relative
permeabilities has been modified both for the grid block properties calculation and also for
VDRP effects upon the well generalized pseudo-pressure (GPP) calculation where this
option has been selected. For the grid block calculation, the two-phase oil relative
permeability to gas is now calculated from the two-phase gas relative permeability to oil.
For versions prior to 2013.1, the two-phase oil relative permeability to gas was calculated
from the three-phase gas relative permeability. For the GPP calculation, the three-phase gas
and oil relative permeabilities are now calculated in an identical manner to that employed
for the grid block; this involves firstly calculating the associated two-phase relative
permeability pairs and combining these to form the three-phase relative permeabilities. For
versions prior to 2013.1, the three-phase oil relative permeability was calculated directly
from the three-phase gas relative permeability. Item 286 of the OPTIONS3 keyword may
be set to 1 to revert to pre-2013.1 behavior.
•
For versions prior 2013.1, there were some circumstances where calculations related to
directional relative permeabilities assumed that end-point scaling was also being modeled.
This has been addressed for 2013.1. Item 287 of the OPTIONS3 keyword may be set to 1
to revert to pre-2013.1 behavior.

For the 2013.1 version, further checks have been added to ensure that the correct defaulting
is applied to the intermediate relative permeability end-points when end-point scaling is
specified in terms of temperature or composition dependence via the ENKRVT or ENKRVC
keywords respectively. Specifically if one or more of the KRGR, KRWR, KRORG or KROWG
end-points is defaulted, the values will be assigned from the corresponding saturation table
values but will be scaled according to the maximum value of KRG, KRW, or KRO which itself
may be defaulted from the table value. Item 290 of the OPTIONS3 keyword may be set to
1 to revert to pre-2012.2 behavior. This should be specified in the RUNSPEC section.
•
The output to the INIT file of default values for the KRGR, KRWR, KRORG and KROWG endpoint scaling keywords (and their imbibition counterparts) when ENDSCALE and
FILLEPS are specified has been modified. From 2012.2 values will be assigned from the
corresponding saturation table values but will be scaled according to the maximum value
of KRG, KRW, or KRO which itself may be defaulted from the table values. Item 290 of the
OPTIONS3 keyword may be set to 1 to revert to pre-2012.2 behavior. This should be
specified in the RUNSPEC section.
•
The new keywords WH2NUM and WH3NUM have been added to provide optional alternative
saturation regions for specifying the WAG hysteresis two-phase and three-phase water
relative permeability saturation functions. This involves some additional saturation table
processing irrespective of whether these keywords are specified or whether the values are
defaulted from the values specified via the SATNUM and IMBNUM keywords. The use of the
new keywords WH2NUM and WH3NUM and the associated additional processing can be
disabled by setting item 296 of the OPTIONS3 keyword to 1.
•
For the rock compaction model, ROCKPAMA or ROCKPAME, the volumetric strain term is
scaled by the multiplier as used when evaluating the adsorption capacities, using different
multipliers for the each components an average multiplier is used by ROCKPAMA. This can
be disabled by using CBMOPTS item 6. Also the derivative modifications of the pre-2013.1
version has been disabled. See OPTIONS3 item 295.
•
For models that include the SOLUBILS keyword, the calculations of water molar density
and water fluid-in-place now take into account the cell salt concentration by making use of
the corresponding brine surface density that is interpolated from SOLUBILS. The pre2013.1 behavior may be recovered by setting OPTIONS3 item 300 equal to 1.
•
For models with end-point scaling specified, corrections have been made to the scaling
algorithms for the case where two-point scaling has been selected (SCALECRS keyword
not specified or specified with item 1 set to No) and where one or more of the keywords
KRWR, KRGR, KRORW and KRORG, or their imbibition counterparts, have been specified. In
addition, corrections have been made to the maximum attainable unscaled water and gas
saturations. Pre-2013.1 behavior can be selected by setting item 301 of the OPTIONS3
keyword to 1.
•
Corrections have been made to the calculation of the oil and gas phase Forchheimer models
which are specified via items 3 and 4 respectively of the VELDEP keyword. Pre-2013.1
behavior can be selected by setting item 302 of the OPTIONS3 keyword to 1.

In MISCIBLE runs, the capillary pressure can be extrapolated beyond the immiscible
values, by setting the maximum surface tension greater than the reference surface tension
(MISCSTR or MISCSTRR). However, pre-2013.1, the capillary pressure
interpolation/extrapolation parameter was limited to 1, preventing extrapolation.
•
The water component type SURF used in keyword CWTYPE has been extended to specify
a surfactant that can be used with both the Foam option and the Surfactant option. The new
type SURFF should be used to define a surfactant for the Foam option only. The new type
SURFS should be used to define a surfactant for the Surfactant option only.
•
For multiple water components option (COMPW), the calculation of the water molar density
at surface conditions is based on the properties of each water component. The same formula
as for reservoir conditions is used and additionally specific values for surface properties can
be supplied with keywords MWWS, DREFWS, CREFWS and PREFWS.
•
Improvements in the handling of ROCKTAB directional transmissibility multipliers, items
3 – 5 (enabled when RKTRMDIR is specified), as well as of keywords ROCKTRMX,
ROCKTRMY and ROCKTRMZ, alter the update of well connection factors during simulation
for any wells completed in the corresponding cells. Moreover, the generalized mobilities of
hydrocarbon components in individual phases are also affected by these changes. The
corresponding item 223 of the OPTIONS3 keyword, controlling the summary output of
well connection factor CTFAC, has been removed. Additionally, a new method of
determining directions of non-neighbor connections while multiplying their
transmissibilities by ROCKTAB (items 3 – 5) may affect the associated flows. Item 294 of
the OPTIONS3 keyword reverts this feature to the pre-2013.1 behavior.
•
A new item has been added to the FOAMFSC keyword that sets the minimum water
saturation for foam, and improves stability in cases where there are cells with very little or
no water.
•
Improvements have been made for tracers associated with multi-component water set using
the TRACER keyword. These improvements relate to the calculation of tracer concentration
and tracer injection and production rates.

used if the standard model should lead to unphysical solutions. The modifications should
be reviewed with the options in CBMOPTS items 4 – 9. In addition it is possible to input
sorption induced strain terms for individual components by TPAMEPS. Note that the

The WELPI keyword has been modified to make it consistent with ECLIPSE 100. Item 2,
the productivity index, can no longer be defaulted and must be given a value.
•
Guide rates set using the GUIDERAT keyword are now set to be greater than 10-6 by
default. This prevents the guide rate becoming very small, and being ignored. A new
argument allows the minimum value to be modified.
•
The algorithm that determines how group targets are distributed to subgroups and wells has
been adjusted to improve speed of convergence and robustness. Pre-2013.1 behavior may
be recovered using OPTIONS3 item 292.
•
For the 2013.1 version, the flow scaling factor calculation used for inflow control devices,
specified in item 11 of keywords WSEGSICD and WSEGAICD, has been altered to take into
account changes to the well structure that take place after the device has been defined. This
change only affects the calculation when item 11 is set to 2 and there is a choke defined
with the WSEGTABL keyword that is downstream of the inflow control device; all other
flow scaling factor calculations are otherwise unaffected.
•
In 2012.1, parallel runs with VELDEP were restricted to cases where wells did not cross the
parallel partitions (that is, no off-processor connections were allowed). This restriction has
been removed for 2013.1.
•
Due to the improved processing of satellite groups of wells (keywords GSATCOMP,
GSATPROD and GSATINJE), mass densities and mass rates of produced or injected fluids
now substantially differ from previously computed results, while the volumetric rates of
parent groups are affected only marginally.
•
Due to an improvement in thermal flash calculations, various volume-related summary
results (for example FOIPG, GGOR and WWCT) may differ from those obtained before the
2013.1 release. The convergence of thermal runs has been also improved. The pre-2013.1
behavior may be recovered by setting the OPTIONS3 item 303 to 1.

Description
CBMOPTS
Item 4 can be used to activate monitoring of passes through the rebound region
(where the pore volume derivative changes sign) when using the Palmer-Mansoori
rock model as specified by the ROCKPAMA or ROCKPAME keyword. This enables
the output of the number of passes through the rebound region using mnemonic
NPMREB in RPTSCHED or RPTRST.
CBMOPTS
Item 5 can be used to select a different modeling of the volumetric strain term of
the Palmer-Mansoori model, ROCKPAMA. For cases where the sorption diffusion
process is slow, the instant adsorption assumption of the strain term might not be
valid. This could result in a negative total compressibility and in the limiting case
the reservoir equations cannot be solved. The coal is swelling/shrinking without
the corresponding exchange of gas. For such cases, the alternative forms enabled
by this item should be considered.
CBMOPTS
Item 6 can be used to request a scaling/no-scaling of the Palmer-Mansoori strain
term of ROCKPAMA or ROCKPAME, by using the same scaling as used for the
adsorption capacities.
CBMOPTS
Item 7 can be used to request that the pore volume and/or the transmissibilities
should be altered by the Palmer-Mansoori model, ROCKPAMA or ROCKPAME, so

ECLIPSE
Dual tubing injector pressure control
For secondary injection wells, a limit may be imposed both upon the maximum injection
pressure in the secondary well segment and a maximum pressure in an additional nominated
segment. When the well is opened via the SCONINJE or STEST keywords, these maximum
pressure limits are not honored prior to opening, and injection will typically continue for the
duration of a time step before the secondary well is closed due to these limits. This situation may
be circumvented by delaying the opening of the well until these limits no longer apply.

1
The keyword TRPLPORO (triple porosity feature) may not be used if dual permeability
(keyword DUALPERM) is present.
2
There is a known issue with the Polymer shear thinning functionality which can generate
convergence issues even with relatively moderate multiplier values. The issue can also
persist when thickening at higher velocities is introduced. The PLYSHLOG keyword
introduced in the 2013.1 release of ECLIPSE is a more robust formulation of polymer shear
effects on rheology and should be used in preference to PLYSHEAR.
3
There is a known issue with LGRCOPY when trying to copy to radial geometry. Only
properties which also exist in the Cartesian global grid can be copied using LGRCOPY. For
instance, PERMR cannot be copied since the global grid has only PERMX and PERMY (and
PERMZ) defined.

There is a known issue concerning the use of the POLYMER keyword with local grid
refinements that can cause convergence problems. When using polymer injection via wells
placed in local grid refinements, it is recommended that the time stepping of the simulation
is kept small.
5
In cases where the simulation model is initialized by means of enumerated saturations, the
warning message(s) issued when one or more values are found to be inconsistent is
potentially unclear. In particular, the details provided may not be appropriate for identifying
the grid block(s) in which this situation occurs. If this warning message is encountered, it
is recommended that the input enumerated saturation values are checked, in particular, for
consistency with the input saturation functions.
6
The keyword PLYDHFLF is available in ECLIPSE 100 from version 2012.1 It activates
thermal degradation of polymer when the temperature option is turned on, and provides a
half-life for the process. The half-life applies to both polymer in solution and polymer
adsorbed on the rock.
If the polymer does not desorb from the rock once adsorbed (PLYROCK keyword, item 4
set to 2), the adsorbed polymer will still thermally degrade. For stability reasons, this
degradation is currently disabled if the solver forces the solution polymer concentration to
a negative value (which is usually small, of the order of -10-6). If the solver repeatedly
creates such small negative concentrations during the Newton iterations, then the
degradation half-life may be artificially increased, even if the final converged polymer
concentration is greater than zero. It may be possible to protect against this by retaining a
low level of polymer concentration outside the injected slug, but otherwise you should
contact support for assistance.
7
You should avoid putting lines of comment into the DYNAMICR keyword.
8
When using UDQs and group quantities for the normal network model, the entire FIELD
is not included as a group quantity, while FIELD is present for the extended network model.
9
When running in parallel, or with reservoir coupling, ECLIPSE 100 does not gather all
warning, error and bug messages to the main processor for output. If a parallel run fails to
complete, then investigation of the .MSG and .PRT files output by slave processors often
helps in the analysis of the issue. For a parallel run, these files have a suffix .X.MSG or
.X.PRT where X is the processor number. This applies to normal termination, abnormal
termination or when the program stops responding. Resolution of any errors discovered on
slave processors may allow the simulation run to proceed normally.
10 There are unresolved issues with UDQs of the type “GU” in extended network modeling
cases. We advise that you avoid using these UDQs in such cases.
11 When transmissibility multipliers from ROCKTABH are determined, the explicit value of
the pressure is used rather than the implicit value. Normally this has very little effect.
However if there is a change in the SCHEDULE section which causes a large pressure
change where the multipliers also change rapidly with pressure, then for the next timestep,
the multiplier selected may not reflect the new pressure accurately. To avoid this, you are
advised to put in a single very small timestep immediately following any such changes.
12 When running a simulation on Linux in parallel and with very large grids, the run may
terminate without issuing any warnings or errors. If the run is repeated in serial, an error
should be output indicating an issue in the allocation of sufficient memory. In some cases
the issue may be avoided by using a larger number of processors to further partition the
grid.
13 The BEWKR summary vector, defined as the effective relative permeability of water due to
polymer, is in some cases incorrect. This is a reporting issue only; the underlying physics
is solved correctly.

ECLIPSE Suite Release Notes
14 Using PLYVISCS with the TEMP option but without the TEMPNODE keyword produces an
unexpected error message. PLYVISCS does not need the TEMPNODE values, only the
SALTNODE ones, and therefore it should work without TEMPNODE. The work around is to
add the requested TEMPNODE table, even if not used. This issue was introduced in the
ECLIPSE 2012.2 release.
15 It is possible for the simulator to experience convergence problems if polymer injection
starts suddenly when long timesteps are being taken. Improved problem detection and
timestep chopping should prevent the majority of these from aborting the run, but it may
still be possible for a zero determinant bug to occur. In this case, you should reduce the
timestep shortly before start of injection.
16 Polymer flood cases where the polymer adsorption depends on salinity, that is using the
PLYADSS keyword, may experience convergence problems. The cause of this is still
unknown, but in some cases improvements may be made by:
•
increasing the sizes of NSTACK and LITMAX
•
ensuring that the range of values in the SALTNODE and ADSALNOD keywords extend
beyond the range of the salinity values used in the simulation run
•
controlling the timestep size to a smaller value at major changes in the injected
polymer concentration.
17 There is a known issue regarding the reporting of shear viscosities for fringe cells in parallel
runs using the PLYSHLOG and PLYSHEAR options. For a particular subset of the fringe
cells, the shear viscosity values are reported by a different processor to that actually
performing the calculations for the fringe cell involved. This is a reporting issue whereby
the appropriate shear thinning/thickening effect may not be observed in the shear viscosity
output for particular fringe cells.
18 OPTIONS item 200 will not revert certain more extreme behaviors of the pre-2013.1
Palmer-Mansoori rock compaction model implementation, such as negative permeability
multipliers. This may mean that pre-2013.1 behavior cannot be recovered for certain
models.
19 SOLVFRAC values are not transcribed from the global grid into LGRs. It is also not
possible to specify SOLVFRAC values manually using REFINE in the SOLUTION section.
This results in a zero SOLVFRAC value being used in LGR cells.
20 The keyword PLYADSS allows users of the POLYMER model to provide a salinity
dependence to the amount of polymer adsorbed. When the adsorption of the polymer is
made irreversible (PLYROCK item 4 set to 2), it has been found that changes in salinity can
cause desorption in some cases. Users of this combination of options are advised to exercise
caution in using this keyword, or to use the salinity-independent keyword PLYADS as an
alternative. An improved implementation of PLYADSS with irreversible adsorption is
under development.
ECLIPSE 300
1
The Optimization option in ECLIPSE 300 will not output any solutions (PRESSURE,
SOIL, etc.) for time T=0 when multiple output is requested. This known issue does not
cause any simulation problems in ECLIPSE 300, it only affects the visualization results for
T=0 in FloViz for example.
ECLIPSE Suite Release Notes

2
In ECLIPSE 300, the BDENSITY keyword has limited application within the BRINE
option. If BDENSITY is used, the simulator will only satisfactorily convert between the
number of moles of water and the corresponding water volume when the salt concentration
of the injected water matches the initial salt concentration in the reservoir. In such cases,
this salt concentration value must be entered as the reference salt concentration in
PVTWSALT.
3
In the pre-2011.1 version of ECLIPSE 300, a combination of LGRs and analytical aquifers
connected to the reservoir with no direct contact with LGRs (using the AQUANCON
keyword) may give incorrect aquifer connections. This issue occurs in both serial and
parallel modes.
In ECLIPSE 2011.1, the problem is resolved for serial runs, but may still appear in parallel
runs. Aquifer connections are created correctly in ECLIPSE 100 for both serial and parallel
runs. To connect an analytic aquifer with an LGR cell, the AQANCONL keyword must be
used in ECLIPSE 300.
4
When using multiple instances of the PRIORITY keyword to limit group production
rate(s), there may be occasions where wells that have previously had a priority calculated
are not correctly updated on the reading of the new keyword. These wells are only updated
at the next scheduled time (calculated from record 1 of the previous PRIORITY keyword).
To ensure that all wells have updated priorities when a new PRIORITY keyword is
specified, it should state that the update period is “0”, which ensures that all wells are
updated on that timestep. After a timestep has occurred, a further instance of the
PRIORITY keyword, with all coefficients equal to the previous instance, should be placed
with the desired update period.
5
Improvements have been made when calculating the equilibrium deviation terms
(EQLDREAC keyword) which might affect the rate of the chemical reaction. The pre2013.1 behavior can be recovered by setting item 305 of OPTIONS3 keyword to 1.
6
For OPTIONS3 item 302, the underlying calculations of the Forchheimer Beta coefficients
have not been changed. The corrections only apply to the reporting of the values.
ECLIPSE 300 thermal
1
The steam trap control can be unstable, particularly in SAGD simulations where there are
many completions. As a result, the production rate can oscillate and time steps may be quite
small. Small differences in simulation, for example between different versions, can shift
these oscillations which gives the impression that the answers have changed. In fact the
average production rate stays the same, but the “noise” changes.
2
If you are using Petrel 2013.1 to export a THERMAL, DUALPORO model, do not select the
Calculate and export the transmissibility and pore volumes option in the Define
Simulation Case/Transmissibilities Tab. If you do select the option, the rock volumes
that are exported to the GSG file will be wrong. Until this Petrel issue has been resolved,
you are advised to allow ECLIPSE 300 Thermal to generate the rock volumes internally
which is what happens if you do not select the option.
Hysteretic rock compaction model
There is a known issue with the Hysteretic Rock Compaction Model and elastic initial
conditions (ROCKOPTS item 4 set to ELASTIC). The table look-up initialization may not
converge in some cases, with ECLIPSE 100 reporting an error and ECLIPSE 300 reporting a
simple message.

ECLIPSE Suite Release Notes
Multi-segment wells
For both ECLIPSE 100 Blackoil and ECLIPSE 300 Compositional, multi-segment wells that
include a large number of segments and looped flow paths can experience severe convergence
problems. When this occurs, convergence can sometimes be improved by excluding
acceleration in the well pressure drop calculation method (WELSEGS item 6) and/or reducing
the number of segments and loops.
Parallel ECLIPSE
1
There are known limitations with the combination of PINCHXY and the Parallel option. If
the simulation model contains complex geometry, for instance, Y-shaped faults, we would
recommend that the Petrel software is used to define the geometry and NNCs correctly.
This information can be imported into ECLIPSE using a Generic Simulation Grid (.GSG).
2
There is a known issue concerning the use of single-porosity regions (using the DPNUM
keyword) for dual-porosity parallel runs in the ECLIPSE 100 and ECIPSE 300 reservoir
simulators. It principally arises where the dual-porosity region is small and is surrounded
by a large single-porosity region. This is due to the fact that on some processors, only single
porosity cells occur. This may result in a communication mismatch between processors
with and without dual porosity cells and therefore causing the simulation to fail. The most
reliable workaround is to make at least one cell on each processor dual porosity (that is with
DPNUM=1).
Polymer (brine)
It is recommended that the polymer (brine) feature is not used if connate water is close to zero
as the system will then not be adequately defined. This could result in an inaccurate polymer
(brine) concentration and/or convergence problems.
ROCKPAMA
The equation defining cm in the documentation for the ROCKPAMA keyword contains a factor
g which is not mentioned in the equivalent definition of cm in the "ECLIPSE Technical
Description" for the Palmer-Mansoori rock model. The factor g may be set by ROCKPAMA item
8, and defaults to 1.0. The equation in the "ECLIPSE Reference Manual" is the more general
form, and reduces to the technical description equation when the default value is used.
ECLIPSE Office
1
When a dataset is imported from a directory other than the working directory, the contents
of the All Keywords Tab in the Case Definition can sometimes be empty. It is
recommended that the Import file be first copied to the working directory. If keywords are
missing after importing a case using Case Import, it is advisable to load the data directly
into a new Project using File | New Project.
2
Recently altered keywords now always appear in Generic mode; this is because additional
features would have been lost in the conventional UI mode.
3
Under some circumstances, datasets beginning with an INCLUDE keyword are incorrectly
parsed and it is recommended that you explicitly copy the contents of the INCLUDE file
into the dataset.
4
Saturation plots do not work with negative Pcow values.
ECLIPSE Suite Release Notes

5
It is not possible to run a VOI simulation using the ECLRUN environment. This is because
the FLUX files are deleted prior to the new simulation. It is highly recommended that the
new simulation be moved to a fresh directory with a new name.
6
In general there is very limited support for the Dynamic Region keywords (EQUALREG,
COPYREG, ADDREG, MULTIREG) within ECLIPSE Office.
7
With the Generic Keywords option ON, Multiple Realizations, Multiple Sensitivities,
Correlations, Show plot, Box operations, Calculator, Update Case, View Model in Data
Manager and View Model in Grid Section are disabled.
8
ECLIPSE Office is unable to calculate the totals for Summary vectors when two or more
cases are loaded into the Result Viewer.
9
When the Generic Keywords option is ON, ECLIPSE Office cannot update the RUNSPEC
dimensions based on the keyword data provided in the other sections. This has to be done
manually using the Dimension Overrides Section.
10 Nested Local Grid Refinements are not supported.
11 The Result Viewer is not capable of reading user-defined units.
12 ECLIPSE Office incorrectly treats IMPES and DIMPES as aliases.
13 Launching from Petrel under a Petrel License checks out a standalone license instead of
using multiple license servers.
14 XMF, YMF and ZMF are dimensioned to the number of components * grid size. If the model
contains water (or multi-component water) the array will not be properly expanded.
15 The DATES and START keywords do not support time.
16 It is not possible to add some of the tracer keywords to the SUMMARY section using the
ECLIPSE Office user interface, for example GTICF, GTICS, GTPCF, GTPCS, WTICF,
WTICS, WTPCF, WTPCS, CTPR and CTPT.
17 ECLIPSE office is not compatible with NVIDIA nView software.
18 Most defects in the scaling of relative permeability curves were fixed in the 2011.1 version.
However, the ECLIPSE office result viewer may still show inaccurate scaled curves with
some end points. This is a post-processor reporting issue only; the simulation end-point
scaling and results are not affected.
19 You cannot load an empty SMSPEC file into the Results Viewer module of ECLIPSE
Office. This may cause the current version of OFFICE to fail.
20 The ECLIPSE Office user interface has buttons which launch other pre and post-processor
applications. These buttons are greyed out if pre-2012.1 versions of ECLIPSE Office have
not been previously installed on your computer. The workaround is to launch these
applications using the Simulation Launcher.
ECLRUN
If the data deck contains either reservoir coupling or parallel (or both), the features do not need
to appear in the LICENSES keyword. Adding them there may well cause problems with
ECLRUN.

Well Auto Connect works very slowly with large grids.
2
The Save and Restore feature of FloGrid is disabled. To enable the feature (not
recommended), modify $eclrc.bat to remove the line.
===============================================

: ===============================================
SET ECL_UTSR_HEAP=PROCESS
The Save and Restore feature has been withdrawn from FloGrid for 64-bit platforms.
FloViz
1
Visualization problems can occur in FloViz when multiple output is requested from the
Optimization option in ECLIPSE 300. It will not output any solutions (PRESSURE, SOIL,
etc.) for time T=0 when multiple output is requested. This known issue does not cause any
simulation problems in ECLIPSE 300, it only affects the visualization results for T=0.
2
Units for SFIPOIL and others are not displayed. These units are sm3 and Mscf for
SFIPGAS.
3
FloViz may fail while reading in FrontSim models which include .GRID and .INIT files if
ACTNUM, in the GRID section, inactivates cells. The work around is to use Petrel.
FrontSim
Aquifer
1
The aquifer facility in FrontSim can produce different initial transient rates compared to an
ECLIPSE run on the same model. FrontSim may calculate a spike rate on a non-converged,
initial, large time step. Reducing the initial time steps and tuning can help to reduce this
effect. Typically the steady state aquifer rate should match with ECLIPSE.
2
The aquifer option does not support connection to active cell faces within the grid.
3
The aquifer option does not allow a single cell face to be connected to multiple aquifers.
Dual porosity
In some Dual Porosity models, the translation of volumes from reservoir to surface conditions
does not exactly honor the input PVT.
End-point scaling
The output of scaled capillary pressure to the debug file is incorrect.

Generic simulation grid (GSG)
FrontSim and ECLIPSE have different ways of handling GSG Transmissibility and Pore
Volume (T&PV) cells that have zero PORO. ECLIPSE can use PORV in the T&PV workflow to
activate such cells, while FrontSim does not activate such cells when non-zero PORV values are
input. As a result, we expect a small difference in the number of active cells for such models
between ECLIPSE and FrontSim.
Input/output
1
The Field unit output of heat capacity is incorrect.
2
Fluid-in-place values reported in the PRT file are in surface units for black oil. For the
compositional model the values are in reservoir units and the gas in place is in Mrcf (1000
Reservoir Cubic Feet) instead of Mrb (1000 Reservoir Barrel).
3
FloViz can fail while reading in FrontSim models that include .GRID and .INIT files if
there ACTNUM keywords in the GRID section that inactivate cells. The work around is to
use Petrel.
4
The initial oil-in-place reported in the fscat file is actually the remaining oil-in-place at the
end of the simulation/time step.
Keywords
If MINVALUE is specified with more than one record, an error message is given. The work
around is to use multiple keywords with only one record.
Keyword reader
If the terminating slash is missing for a SCHEDULE keyword with multiple records, it could
potentially lead to unexpected behavior, for example, the subsequent keyword will not be parsed
correctly.
Pattern flood management (PFM)
A pattern flooding producer may unexpectedly stop producing when WECON is used to specify
the minimum oil rate. The work around for this is to avoid using WECON during pattern flooding
until the issue has been resolved.
Restart
A FrontSim run cannot be restarted from an ECLIPSE tracer run.
Saturation solver
The FrontSim three-phase saturation solver may behave incorrectly with the combination of
three-point end-point scaling, an RV (vaporized oil) variable table, and with gravity segregation
switched on.
Well model

52
A well’s individual rate limit may not be honored when this well is switched to BHP control
due to the inability to meet a user-defined target.
Known issues
2013.1 release known issues
ECLIPSE Suite Release Notes
2
The well PI reported by FrontSim is based on total mobility and will be different from that
reported by ECLIPSE which is based on the mobility of the primary phase.
3
The TRACK option in COMPORD may not always order connections in the correct order for
very complex wells. You are advised to check the connections sequence for accuracy and
then to order them manually. Incorrect sequences of connections can sometimes create
problems during the solution process.
4
FrontSim sometimes show spikes when the target is controlled at group control level.
5
FrontSim sometimes does not manage to maintain rate limits (limits violated) when a well
is converted from group rate control to individual BHP control.
6
The steady-state productivity/injectivity index value of the well that is supported by the
WELPI keyword is treated by FrontSim as a total (all phases) PI at reservoir conditions not surface conditions as described in the FrontSim User Guide. This is different from the
behavior of ECLIPSE, which uses the PI for the phase indicated by WELSPECS item 6 at
surface conditions.
7
There can be minor differences in results for the same dataset between platforms (Linux or
PC) as well as between released versions. These can be due to different compiler versions
and/or new enhancements. The pattern flood management (PFM) algorithm can be
particularly sensitive to minor differences in results for well rates resulting in different
allocations of injection rates.
PVTi
1
First-contact and multiple-contact miscibility tests may not work for some cases with PVTi
since the 2008.1 release. The solution is to use earlier versions of PVTi.
2
Regression on Normal variables may stop working after Whitson splitting. The solution is
to use Multi-feed splitting or earlier versions of PVTi (before 2007.1).
3
The Composition with Depth Experiment is limited to isothermal cases.
Systems
Beta and official installations
1
If you have installed a beta version of ECLIPSE 2013.1, you must uninstall it before
installing the official release.
2
When upgrading ECLIPSE, that is, you have a previous version installed, please ensure that
all programs in the ECLIPSE suite are closed before starting the installation. This includes
in particular the Simulation Launcher program and the eclrun script. If they are open, they
will not be upgraded and the old versions will persist. If this does happen, uninstall the
ECLIPSE upgrade version, ensure that all programs are closed, and then re-install it.

Warning
Be very careful when creating these links as any linking errors can lead to
major system errors.
2
If you are using Windows 7 to run an ECLIPSE model from a directory that is shared, you
must have read and write access to that shared directory. This applies even if ECLIPSE is
being run directly on the machine sharing the directory.
3
When using IBM Power, Parallel ECLIPSE and ECLIPSE 300 are only supported on a
single server. Parallel processing across multiple machines is not supported.
4
On some systems the following error maybe seen when any of the pre- and post-processing
applications are started:
The program can't start because MSVCR100.dll is missing from
your computer. Try reinstalling the program to fix this
problem.
To correct this issue, install the Microsoft runtime from the DVD. The installer is on the
DVD in the 3rdparty\PC\resource\vcredist_vs10 directory.
Licensing
Including license features for two different versions of the software (for example 2011 and
2013) in the same license file on the same server may produce issues when running the software.
Linux
1
It is not currently possible to submit jobs from one architecture of Linux system to another.
Jobs must be submitted on the same type of system to that which they will run on. For
example if your job is submitted from a system based on x86_64 architecture it must run
on an x86_64 based system. Submitting jobs on x86_64 to run on IBM Power will not
work.
2
There are issues with PBSPro, Torque and Intel MPI.
If you are running PBSPro as your scheduling system, you should set the environment
variable ECL_PBS_CORES_PERNODE to the number of cores per node (for a
Nehalem/Westmere system this is eight and for a Sandy Bridge system this is 16).
Set the variable in the .cshrc file if you are running c-shell or .bashrc if running the
bash shell.
The default chunking of 1 may not work in all cases using Intel MPI, but Platform MPI
works and this setting is not required.
54
3
Running Torque with Intel MPI is not supported. Please use Platform MPI instead.
4
PBSPro has a limit of 15 characters for the job name, which must also begin with a letter.
eclrun (the script which submits jobs for Petrel and the Simulation Launcher) uses the name
of the dataset as the job name. This means that any datasets that it submits to PBSPro must
also have a name of 15 characters or less that start with a letter.
