Production System Optimization by using Electrical Submersible Pump Case Study -Abugabra field-Sudan

Abstract

During the reservoir production life reservoir pressure will decline. Also after water breakthrough the fluid column weight will increase as hydrostatic pressure will increase because of increased water and oil mixture density. In this case, reservoir pressure may not be enough to lift up the fluid from bottom to the surface. These reasons decrease or even may cause to stop flowing of fluids from the well. Some techniques must be applied to prevent the production decline.A small change in water cut gives a large change in oil production. This study uses a simulated model of the PIPESIM artificial lift method based on the operating limits of the electrical submersible pump artificial lift technique applied to the MOGA well and SUF3 at the Abu GAbra field in Sudan. The results from the advanced simulation model show that the ESP solution gives a production rate ranging from (0-799.98 STB/D) a pump type (REDA D1050N 140 stages, 2916.7 RPM, 50 Hz) for a MOGA well and a production rate ranging from (0- 1500.202 STB/D) a pump type (REDA DN 1800 737 stages, 2916.7 RPM, 50 Hz) for a SUF3 well.
