Abstract

Summary

This study focuses on the Mishrif reservoir in Rumaila oilfield. This reservoir started to produce since 1975 without any energy supply, and most of the producers were ceased to produce because of the low reservoir pressure. Therefore, water injection pilot was conducted since 2010, and the expanded water injection was started since 2013. After 2 years water injection, several producers are back to production and the production rate of several wells is increasing significantly. However, a number of problems are arisen, and the most striking one is the existence of thief zones. Thief zones led to early water breakthrough and fast water cut development and eventually lower the sweep efficiency and impact water injection performance. In order to cope with this problem, the dynamic behavior of thief zone in Mishrif reservoir is presented, and mechanism study is conducted to optimize the water flooding. Results indicate that the existence of thief zones can significantly impact the water injection performance, and optimizing perforation strategy is an effective way to mitigate this problem.
