Additives For Steam Foam

banner-placeholder

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:

Steam Flood and continuous or cyclic steam injection

Results:

Thermal stability of specific surfactants has been demonstrated up to 250 °C in anaerobic conditions. Good foam stability has been demonstrated up to 200°C.
