CCUS-EOR Optimization to Achieve Zero Emission Program Targets in Northwest Java Basin

The presence of oil and gas production fields, oil refineries, cement plants, and coalfired power plants situated close to each other supports the program for zero CO2 emissions through Carbon Capture, Utilization, and Storage (CCUS) for Enhanced Oil Recovery (EOR). This study aims to investigate the potential of depleted fields in the North West Java Basin as the target for CCUS-EOR in fulfilling the zero CO2 emission program and boosting oil production. The study uses oil and gas field data to evaluate the CCUS potential both qualitatively and quantitatively. The Geographic Information System was applied through a clustering method with a 50 km and 100 km buffer from CO2 emission sources. The calculation of CO2 for EOR purposes with a 50 km buffer radius is 287.504 million tons, which could result in a 575.009 million stock tank barrel (STB) increase in oil production in the case of immiscible injection and 379.506 million tons for an increase of about 1.150 billion STB of oil production in the case of miscible injection. For a 100 km buffer radius, 632.541 million tons of CO2 is required to increase 1.265 billion STB of oil production in the case of immiscible injection and 834.955 million tons of CO2 for an increase of 2.530 billion STB of oil production in the case of miscible ijection. These results are expected to be implemented as part of the program to reach the goal of producing 1 million barrels of oil per day by 2030 and achieving net zero emissions by 2060.
