Current usage in Total

Added value of WITSML today and tomorrow
Addresses niche domains:
 Lithology
 Mud logging
Foot print will expend with
technological advances
 Well seismic (passive, micro)
 EOR
Attributes call for:
 Data quality, sanity and
traceability
 Search tools leveraging
ASCII XML open format
ensure:
 Unlimited compatibility through
mapping
 Custom made data sharing &
Data Management solutions
without duplication of data
3 - WITSML May15, 2008
Well data shared with other
application domains

Background of Total uptake of WITSML
Joined WITSML SIG in 2005:
 Well site geology
 Geosteering
 Well placement
Data acquisition in WITSML in affiliates:




United Kingdom
Netherlands
Indonesia
…
Concurrent with enhanced awareness on Data Management issues





Drawbacks of proprietary formats
New data sets more complex and large
Stronger needs of cross discipline data exchange
Sanity check of corporate exploration data stores worldwide
Preparing for Web Services distribution of reference data
4 - WITSML May15, 2008
A two dimensional expansion
Geographical:
 More and more affiliate now familiar with secure data streaming from rig to base are ready for
integration and require corporate solution
From acquisition to interpretation:
 Leveraging Mud log and Litho logy data for Rig Base and Rig Headquarter collaboration via
automated data streaming into G&G application

Composite Realtime displays
Smart Tools for
events analysis
WITSML feed to
Total applications
Partners
Service companies
Requirements :
Cost efficiency: no fancy RTOC
Fast implementation along with drilling
Double replication at base and headquarters
Comply with corporate security policies
 Use of a ‘DMZ’ and Firewall to isolate Total and Contractor Networks
Seamless transfer from acquisition to technical interpretation and database
 Ex: Pore pressure analysis, petrophysical interpretation
 Data streaming into Gravitas
3 data acquisition companies, 4 software companies:
 M/LWD data generated in WITS 0 and converted to WITSML 1.2
 Mudlog and lithology generated in WITSML 1.3.1
8 - WITSML May15, 2008
Results at base and headquarters
During the 2 months length of drilling:
Petrolink tools completed



Onsite aggregation, (WITS0 to WITSML conversion)
Affiliate WITSML servers ( 1.2 and 1.3)
HQ mirror WITSML servers (1.2 and 1.3)

through ‘DMZ’ and Firewall isolating Networks
HRH Gravitas & WinDOT could



read and send WITSML 1.3.1 data
Minor bugs reported
Proposed increased user functionalities
KSI Drillworks Predict – ConnectML

Could read 1.3.1
Major
benefits in Well site geology data management and
well surveillance
9 - WITSML May15, 2008
Lessons learned
Single version of WITSML to be favored
Back up configuration necessary in case of failure during drilling
24/7 operations require IT staff availability and bring the industrial culture into
the office
Remote access requires explicit naming conventions
Software testing uncover new development possibilities
Technical benefits are Immediate
 Faster loop to interpretation
 Richer specialist support
Organisational benefits require well site personnel adoption
 “Big Brother” syndrome – Possible impact on Well-site Personnel
Distance requires full responsibility of each team member and rigorous data
management

Ubiquitous web actors
Each of us is now connected everywhere
Each of us is an actor in the chain of processing
Tasks are performed in and out of the organization
We expect from the technical tools the same performance level as private
applications
Security rules must adjust to such behaviors
Collaboration tools and Data storage allow us to focus on the content rather
than the container
Huge prospect of applications development
which understand the documents and actions they are processing for us.
