Abstract

Natural resources found in the pores of rocks and beneath the earth's surface include oil and gas. In the oil and gas industry, when initial conditions are stable, the pressure within the reservoir can naturally push the fluid to surface. Once a well is drilled through the reservoir and put into production, there is a pressure drop around the borehole, prompting the use of artificial lift methods. Artificial lift is used to assist process of lifting fluid from the bottom of the well to surface. Well X was no longer able to produce naturally and had an SRP. There is a decline in production during production process. Gross up program can be conducted to prevent the decline in production capacity and oil production rate from the well. Gross up is a program to increase the gross production rate by converting SRP to ESP. The objective is to calculate the evaluation of the artificial lift installed in the form of an ESP. The calculations performed include oil reserves, well X performance, using pipesim software with tubing ID, operating frequency, and stage parameters. The conclusion of this research is that the installed artificial lift, namely the ESP pump, is optimal based on pump performance.

Abstract

Well X is one of the oil wells located in field Y that has been producing using artificial lift. Well X has changed the artificial lift from SRP to ESP to optimize the well production rate due to a decrease in production. Electrical submersible pump is a multistage centrifugal pump with several impellers and diffusers at each stage. The current pump data uses 21 stages and a frequency of 45 Hz with an oil production rate of 7.1 bopd and a water cut of 99%. The well production capacity known by using IPR is 4542.436 bfpd. From the production history data, the author calculates the remaining reserves that can be produced until the q-limit with the Decline Curve Analysis (DCA) method. Next, an evaluation of the installed ESP pump is conducted using the pipesim simulator. This evaluation involves nodal analysis and sensitivity testing to assess the pump performance and optimize the flowrate production. The analysis results show the remaining reserves that can be produced are 2043 MSTB. Sensitivity tests on tubing size, stages, and frequency indicated that the pump operates optimally with a tubing size of 2.992 inches, 21 stages, and a frequency of 45 Hz, resulting in a production rate of 3503.85 STB/d at a pressure of 88.86 psi. The research result show that the ESP pump operates optimally, and the use of ESP has been proven to increase the production rate from 3133,4 STB/d to 3503,85 STB/d.  Keywords : DCA, ESP, nodal analysis, optimum production
