Preliminary Study on Gas Storage Capacity and Gas-in-Place for CBM Potential in Balingian Coalfield, Sarawak Malaysia

This project focuses on Coal Bed Methane (CBM) potential in Balingian coalfield, Sarawak. One block in Balingian area is picked as an area for preliminary assessment. Liang formation (Balingian Coal) is lignite coal with a mean vitrinite reflectance of 0.32%, coal seam thickness from 0.33- 29.69 ft....
