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.
