Abstract

The majority artificial lift used in MPA Field use PCTGL (Permanent coil tubing gas lift). PCTGL is installed on several monobore well or dual monobore well. Some wells in the MPA Field have waxy HPPO oil character with pour point between 85-100oF with API between 30-35. The well "MM-1" has a HPPO character with pour point 95oF. The character high Pour point oil of the well will be problem to be solved. The MM-1 well is produced with PCTGL. From the simulation, a PCTGL design was obtained at a depth of 2250 ft. With the character of HPPO oil, pour point depressant injection optimization is also carried out along with the injection of gas lift so that the chemical can work from the downhole. The results of the bottle test of pour point depressant use concentration of 1000 ppm to reach the target. The results of the field test showed that the concentration of Pour Point Depressant of 1026 ppm was able to change the pour point up to 65oF. The results of optimization production showed that the production of MM-1 wells was able to increase with production of 290 bopd.

Abstract

The Anggana Field, located in Kutai Kartanegara Regency, East Kalimantan, is part of Pertamina Hulu Indonesia (PHI) Zone 9, which manages several mature oil and gas fields in the Mahakam region. The discovery of new gas reserves in Anggana presents an opportunity to enhance production, but the existing surface facilities were primarily designed for oil handling and are limited in gas capacity. This study focuses on the technical optimization of gas transportation from Anggana by using PIPESIM software to simulate network performance and flow assurance under different pipeline configurations. Simulation scenarios were designed to evaluate two configurations: (1) a tie-in to the existing Sanga-Sanga gas network and (2) a dedicated pipeline from Anggana to the Lempake Booster Station. The simulation assesses pressure drop, temperature profile, and flow stability across both systems. Results show that the tie-in configuration increases upstream backpressure and reduces throughput, while the dedicated pipeline provides stable pressure distribution and maintains flow assurance without exceeding design limits. This technical analysis demonstrates that PIPESIM is a reliable tool for evaluating production network performance and supports decision-making in brownfield gas developments.
