Hydrocarbon movability study of sapele deep field, Niger Delta, Southern Nigeria

Abstract

Sapele Deep field is an onshore field of OML 41, located in the North-western part (Greater Ughelli depobelt) of the Niger Delta oil province, and it is one of the most prolific fields in the Niger Delta. Well logs from six wells were integrated to study the hydrocarbon movability potential of the field. The hydrocarbon movability potential of the field was delineated by looking at the various hydrocarbon movability factors such as the flushed zone, movable oil saturation, residual oil saturation and hydrocarbon movability index. The study area on an average has flushed zone water saturation (S_xo) of 0.84, hydrocarbon saturation of 0.55, movable hydrocarbon saturation of 0.39, residual hydrocarbon saturation of 0.19 and movable hydrocarbon index of 0.51.
