Multi Problem Resolver to Overcome Gas Interference and Sand Problem on Sucker Rod Pump in Pertamina EP Sangatta

Abstract

Sangatta Field is one member of Pertamina EP Asset 5, which is located in East Kalimantan. The First exploration well has been drilled at 1939 and start producing commercially on 1976 with initial production rate 5.034 BOPD along with peak production rate 9.125 BOPD on 1979. Nowadays, Sangatta Field only produce approximately 1.400 using Sucker Rod Pump (SRP) and gas lift.
Sangatta Field produce from Balikpapan Formation, which is dominated with sand. Due to high pressure decline, bonding among sand grains no longer strong and become easily separated from each other. On the other hand, solution gas trapped in oil has been liberated due to pressure drop below bubble point. This phenomenon leads to another problem which is simplified using term gas interference. Previously, sand problem and gas interference been solved using different tools, sand trap and gas anchor cup type (GACT) which is not really reliable to handle those two problems at the same time. We introduce a tool to overcome that problems named MPR (Multi Problem Resolver).
This paper will discuss about concept, design, and how to install this MPR on SRP so that sand problem and gas interference can be handled at the same time with longer lifetime than using conventional sand trap and GACT. Also we want to present success story when using this MPR on Sangatta Field.
