Advanced Coreflood Studies & Enhanced Oil Recovery (EOR)

Analytical and consulting solutions for enhanced oil recovery (EOR), enabling you to optimize the extraction of your oil beyond that recoverable by primary and secondary methods.

Responding to an ever-increasing demand, petroleum engineers are continually being challenged to develop new and improved techniques and strategies for hydrocarbon recovery. With expert knowledge in sophisticated, multi-disciplinary EOR studies, and our integrated laboratory and consultation services, we offer a comprehensive understanding of your reservoir.
