Evaluation of engineering in ESP installation with various reservoir properties in the offshore X field

Abstract

Oil wells in the x field in the offshore Natuna Indonesia generally use gas lifts as artificial lifts. As time goes, the field enters of oil production decline phase. To maintain oil production and evaluate the other artificial lift, the Electric Submersible Pump or ESP method was conducted on five wells A-01, A-02, A-03, A-04, and A-05, with various reservoir properties. The research objective is to evaluate the technical application of the ESP and obtain the highest potential well to increase oil recovery. The methodology was carried out by collecting field primary data such as reservoir data, Depth, slope, etc. Then the ESP application design is carried out by manually calculating the wells. Result and discussion: based on the calculations, the ESP method can be applied to wells A-01, A-02, A-03, and A-04. A-05 cannot be used well because it has a high turpin meter value (16.35) due to a high GOR (Gas Oil Ratio) value of 2385 SCF/STB. The well with the highest potential to increase oil recovery is well A-01 with the additional oil production +1116 BOPD. It can be concluded that the most potential to be developed into ESP well is A-01.
