الملخص

Waterflooding, a critical methodology in the realm of enhanced oil recovery (EOR) of Libyan oil fields, is implemented subsequent to the depletion of primary reservoir energy. Within the framework of any waterflooding undertaking, the assessments of oil recovery are typically segmented into phases pre- and post-breakthrough. Notwithstanding, the capability to prognosticate waterflood efficiency until the point of abandonment is notably constrained. The primary objective of this investigation is to project the waterflood performance leading up to abandonment in the A-NC186 oil field under a specific water-injection scenario. Through the realization of these objectives, invaluable insights can be garnered to refine reservoir management practices and elevate the efficiency of oil recovery procedures. The outcomes delineate that after 5135 days, a WOR of 82 STB/STB is attained, necessitating the discontinuation of waterflood operations. Notably, a total of 64897 STB of oil was extracted until the breakthrough occurred. The investigation underscores the profound1842859 STB of water produced until the point of abandonment.
