ASP / SP Flooding

banner-placeholder

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.
