The Berau Basin which is located in Northeast Kalimantan is one of the major coal basin in Indonesia are among the prolific gassiest in western Indonesia. The key work in the selection of CBM sweet spot is to look for the area which the tectonic activity can be generated fracture permeability in coal seams. The fracture permeability development in coal seam are related with density of the fracture and cleat within the coal. The CBM sweet spot tend to occur at relatively high permeability compartment. Based on the remote sensing techniques and field geological investigation indicated that coal cleat were shown similar trend in their earth stress. All the result of measurement from the imagery interpretation and field measurement were integrated statistically analysis to defined the trend of regional fracture direction to delineate of CBM sweet spot.
