... Abstract Recovery of bypassed oil banked against non-conductive faults in heavily-faulted and stress-sensitive reservoirs such as the Wilmington and Kern River fields of California can raise concerns of fault destabilization. Here, we investigate the effects of well configuration and well flow...
