Gas Injection EOR
Cleans the well bore, opens clogged pore-space and
channels, improving near-wellbore permeability
Reduces the particle size of the oil to improve the
oil’s viscosity and mobility.
Provide’s a persistent surfactant action downhole
Restores wellbore/reservoir interface (e.g. repairs
“skin damage”)
Reduces interfacial forces.

Surfsol’s patented technology and post treatment effluent are
100% facility compatible.

Surfsol treatment virtually eliminates the possibility of a shutin well with our treatment program because it prevents
precipitation of asphaltenes and paraffin wax crystals.

Surfsol can be used in its liquid-phase for Waterflood EOR to
reduce oil viscosity and neutralize asphaltene and paraffin wax
clogging of reservoir pore space – increasing oil mobility to and
through the wellbore

Surfsol can be used in its vapor-phase for Thermal EOR and

Starting from a Small Pilot Program through
Comprehensive Production Enhancement
Program. The demonstrated increase in
production is offsetting the declining
production curve of this field.
If time is money…
 Surfsol’s process generates an average 30%
gain in incremental oil from wells that are
treated.

The typical time for the treatment process is a
brief 24-48 hours. We’ll get your wells back online quickly.
Benefits of Surfsol’s proprietary
rig-less technology

There is no waiting for work-over rigs
or other scarce resources to start
treating wells and impacting
production. You can deploy those
resources to their highest and best
uses.

Decreased time on site and a small
footprint mean reduced exposure on
the job site.

Surfsol’s proprietary technology is proven to
economically increase oil production even
during periods of low commodity prices.

A fully scalable solution, it may be
implemented on a single well, as a pilot
program, or as a comprehensive production
enhancement program.

Designed to increase the production from moderately
producing fields or fields that have had a consistent decline
in production

Surfsol E4EOR addresses key issues that occur at the
wellbore/reservoir interface which may impede the flow of
heavy oil.

It reverses impeded flow due to blockage at the wellbore
caused by common skin damage mechanisms—asphaltene,
paraffin, inorganic scale, changes in wettability and
emulsion block.

Oil particles attached themselves to the to the conditioned
water, and are held in suspension, preventing re-soiling from
occurring and safely allowing FOG to be permanently dissolved
in water.

The wash off is completely bio-degraded and becomes soil
constituents such as nitrate, dissolved oxygen, carbon dioxide,
biomass and water.

Mixed together in a very diluted water solution, the bio-based
surfactants within Surf-sol drastically reduce surface tension
and work as a dispersing agent that carry other active
ingredients more effectively than common surfactants.

The Problem
The operator of an aging oil field in California with
over 1,050 producing and 1,275 injection wells
had been using water flooding to maintain
reservoir pressure for over 20 years.
Oil production targets were being missed and
continued subsidence had occurred due to
dropping pressure in the reservoir.
This situation was further exacerbated by
injection wells being shut down because injection
pressures were exceeding governmental
allowable limits.


The Solution
Surfsol’s patented proprietary
technology was injected in the
wellbore/reservoir interface and used
to remove mineral accretions and
hydrocarbon/water emulsions in the
flow channels of the rock in the near
wellbore.
A 25% increase in average injection
rates was achieved across the treated
wells. Treatments were accomplished in
2-4 hours and have been effective for 36 months, depending on specific well
conditions and flood water quality.
From the time period of January, 2007
through October 2008, 2,688 treatments
were performed in this program.
 The overall impact in the time period of
study was 712,700 bbls of incremental
oil production.
 This impact was achieved with an
average increase of 3 BOPD ( a 30%
increase) over 2,688 treatments
performed.


An ROI in excess of
500% was achieved
based on the actual
cost of treatment,
production down
time, and assuming
the price of oil per
bbl to be fifty USD.
The operator currently produces 17,000
BOPD from approximately 2,000 wells.
The Solution
 Surfsol was able to treat mechanically
damaged wells that had not previously
been candidates since it does not require
coiled tubing for effective treatment.
 Surfsol for water flood substantially
increased injection rates for over 3
months while keeping injection pressure
within regulatory limits.

Rig-less well interventions using this technology and process
are, not only a success from an incremental production
standpoint, but more importantly an economic success in this
field of operations.

Using rig-less well interventions as the primary method allows
more expensive and limited rig resources to be used more
effectively while managing the reservoir’s decline.

With its lower costs, the Surfsol’s interventions can be used
on a higher percentage of the field’s wells to help arrest the
field’s overall decline rate

Rig-less interventions of this type are a cost effective and
readily available technique for building a pro-active production
enhancement program.
This solution consists of five components:
 Candidate selection
 Treatment design
 Treatment execution
 Evaluation of treatment response
 Refinement of the first three steps based on
the evaluated results.
Key indicators for candidates with a high probability of
success include:

A history of detrimental depositional issues

Thermal stability at a suitable production temperature

Indications of wettability changes induced from other
work-over treatments

The presence of producible oil in the reservoir

Nanotechnology is used to create this powerful line of
environmental friendly oilfield application solutions

Conditioned water is used in conjunction with bio-based
products to increase removal of paraffin, asphaltene
and scale within the well.

Well stimulation products are based the use of all
natural components as well as micro sized conditioned
water particles in order to penetrate deep into the
production zone

Installation of fluid conditioner within well
bore reduces buildup

90 – 120 day effective rate reduces need
for regular treatment

Quarterly maintenance reduces required
work-over treatment for problematic and
mechanically damaged wells
