Enhanced Oil Recovery (EOR)

Enhanced Oil Recovery

Oil Chem Technologies is a technology provider of surfactants used for Chemical Enhanced Oil Recovery (EOR) including ASP and SP.

Differentiating them from other chemical manufacturers, Oil Chem combines 20 years of actual field Chemical Enhanced Oil Recovery experience, patented state-of-the-art surfactant technologies, and strong alliances with world-class chemical manufacturers to provide field-proven surfactants for EOR.

Oil Chem Technologies has been involved with one of the world’s first field-wide ASP projects starting in Daqing, China, using low-concentration, one component ORS-41 surfactant since 1995.  Oil Chem Technologies has since provided over 80 million pounds of surfactants worldwide, which have been successfully injected at an average concentration of 0.1 wt% without co-surfactant, co-solvent, or salinity optimization.  Oil Chem Technologies continues to develop innovative, effective, and economical surfactants based on the field results using their novel chemistries for Enhanced Oil Recovery (EOR).
