Application of Density Lineament Mapping as an Indication of CBM Potential in Tanjung Agung, Muara Enim, South Sumatera

Abstract Coal Bed Methane (CBM) gas is formed and trapped within coal seams, offering significant economic potential as it can be converted into electricity or transported through pipelines for various purposes. Indonesia is estimated to have approximately 574 trillion cubic feet (TCF) of CBM gas reserves, capable of meeting domestic energy needs. South Sumatera is classified as a province with the largest coal reserves in Indonesia, indicating abundant potential for CBM gas resources. This research aims to identify potential CBM indicators based on structural lineament interpretation using DEMNAS data. Field research was conducted to gather necessary data, and the findings from the study indicate that the surveyed area has a high potential for Coal Bed Methane (CBM) due to the high lineament density, ranging from 570/km 2 to 710/km 2 indicating high permeability that supports the well development of CBM gas. Optimal permeability can enhance the quantity of trapped Coal Bed Methane (CBM) gas, given the available space for the gas.
