Production optimization in Well A and Well B using electric submersible pump (ESP)

Abstract

This research discusses the optimization of production carried out in Well A and Well B. The two Wells are production Well with three production layers (multilayer) that have different characteristics for each layer. Based on the performance evaluation of the production Wells, it’s known that Well A and Well B are no longer able to produce naturally (natural flow). Therefore, it’s necessary to have an artificial lift in order to be able to produce.The artificial lift method used for Well A and Well B is to install an electric submersible pump (ESP), because based on the screening criteria of artificial lift, both Wells can use an electric submersible pump. It’s known that Well A has an absolute open flow (AOF) value of 5840 stb/d and Well B of 3874 stb/d. The production optimization carried out has a production target of 70% of the absolute open flow value. Therefore, the selection of the electric submersible pump for each Well must have an operating flowrate that is in accordance with the production target of the two Wells and must perform a sensitivity test on the selected electric submersible pump to obtain the optimal scenario. So that, the electric submersible pump design for Well A is REDA D4300N with operating frequency of 60 hz and 156 stages, while for Well B is REDA DN3100 with operating frequency of 70 hz and 188 stages.
