SUMMARY
SUTIKNO, NIM. 1910247061, Evaluation and Optimization of Electric Submersible Pump (ESP), Supervised and proctoring by Idral Amri dan Adrianto Ahmad.
In primary recovery wells, production fluid tends to decrease, which is caused by a decrease in reservoir pressure and a decrease in pump performance. To overcome the decline in reservoir pressure in primary recovery wells, not much can be done because it really depends on the natural energy contained in the reservoir, so this decline is usually called normal decline. Meanwhile, it is hoped that the decline in production due to pump performance can be minimized by evaluating and optimizing the pump. Decreased ESP performance can occur due to low pump efficiency and suboptimal sizing. For this reason, evaluation and optimization of the ESP unit is very necessary to maintain well production levels in the primary recovery field.
This research aims to evaluate a volumetric evaluation of ESP and determine the maximum and optimal flow rate of wells in primary recovery fields. Next, optimize wells with low pump efficiency indications and wells whose production rates are still far below the optimum flow rate using ESP autograph software. Then calculate the deviation/error from the design compared to the actual flow in the field and find out the percentage increase in fluid and oil after optimization based on the results of well testing in the field.
From the results of the evaluation of well 1 and well 2, it was found that the volumetric efficiency value was below 14%, so it was necessary to optimize the ESP used, then the results of the design optimization of well 1 and well 2 recommended that the pump be replaced with a similar type and size of pump, namely P31 and P23 so that from the results of well tests in the field, there was an increase in oil production from 131.58 BOPD to 207.85 BOPD and from 16.76 BOPD to 51.34 BOPD. The results of further evaluation of wells 3 to well 9 showed that the flow rate before optimization was still below the maximum and optimum flow rate so that wells 3 to well 9 needed to be optimized to increase the actual flow rate. Based on the optimization design, it is recommended to increase the production rate by optimizing to larger pump size. The results of well testing in the field show an increase in production from wells 3 to well 9 amounting to 328.93 BOPD. The deviation that occurs between the design flow and the actual flow after optimization is under 20%. With the right design, it will increase production from wells that are optimized. From the results of well testing of 9 wells that were optimized, additional production of 439.78 BOPD was obtained. The largest increase in fluid and oil gain was found in the well using an inside casing diameter of 6.366 inches. There was an increase in the average fluid rate of 74% and oil rate of 68% after optimization.
