Research on Foam-Assisted Oxygen-Reduced Air Flooding for Enhancing Oil Recovery in Tight Reservoirs
Foam-assisted oxygen-reduced air injection (ORAI) tests were initiated to address critical challenges encountered in the Jiyuan Oilfield within Ordos Basin’s tight reservoirs: pervasive micro-fractures; rapid water breakthrough along dominant fracture planes impairing volumetric sweep efficiency during water flooding;...
