Abstract:
Co-produced waters and gas samples from Coal bed Methane (CBM) production wells together with gas desorption and geological data were used to investigate the gas origin from sub-bituminous to high volatile bituminous coals from the Paleocene Cuervos Formation in the Cesar Sub-basin, Colombia. The Cesar Ranchería Basin (CRB) situated in the north Caribbean region of Colombia (Figure 1), is one of the most productive thermal coal basins in South America and a potential target for CBM exploration and development in Colombia. Previous studies have identified CBM potential in this basin; however, research on the gas origin of co-produced water and gases, methanogenic pathways and controlling factors on gas content had not been studied.
