Solutions
SP for Heavy Oil
Description:
Increase oil production of heavy oil reservoirs while minimizing operational issues using alkali free surfactant-polymer flooding.
Application:
Heavy oil reservoirs where thermal methods are not applicable. From Primary to Tertiary recovery. How it works
Additives For Steam Foam
Description:
Surfactants are used as additives to generate steam foams in thermal EOR. Steam foams improve the efficiency of heavy oil recovery thermal processes. The EOR Alliance developed a workflow to design efficient combinations of additives for steam.
Application:
SAGD and continuous or cyclic steam injection
Adsorption Inhibitors
Description:
With its Adsorption Inhibitor proprietary technology, the EOR Alliance proposes a novel approach to solving the issue of surfactant adsorption in chemical EOR.
Application:
ASP, SP flooding in hard brine, sandstone and carbonate reservoirs.
ASP / SP Flooding
Description:
Increase reserves and oil production by the use of alkalis (A), surfactants (S) and polymers (P) in ASP or SP combinations.
Application:
Surfactant based processes can recover trapped and by-passed oil using surfactants (S) to drastically reduce interfacial tension and polymers (P) to improve mobility control. The alkali can help reducing surfactant adsorption and also can generate in situ surfactants that help reducing interfacial tension. Both alkaline surfactant polymer (ASP) or surfactant polymer (SP) or eventually surfactant(s) alone processes can be envisioned depending on reservoir conditions.
Gas Foams
Description:
Dedicated surfactants are used to generate foam in oil reservoirs, from near-wellbore to in-depth in the formation. These foams improve gas sweep efficiency in CO2 (dense and non-dense), N2 and HC gas floods, resulting in accelerated and augmented recovery. The EOR Alliance has developed a workflow to select specific additives for various gases foams.
Application:
In-depth gas mobility control, conformance treatment, gas shut-off, GOR control, gravity segregation.
Water Management
Description:
Impact of chemical EOR on water management, from the lab to pilot to the field.
Application:
Using our experienced petrophysics and chemical labs, the EOR Alliance will develop a comprehensive workflow to solve water management issues.
Polymer Flooding
Description:
Improve macroscopic sweep efficiency with water soluble polymers to increase oil production rate and accelerate recovery.
Application:
Reservoirs suffering of water channeling issues due to poor mobility control of water (viscous oil and/or unfavorable relative permeability)
