Coalbed methane (CBM) is a type of natural gas that is found in coal deposits. It is formed during the process of coalification, where organic material in coal is broken down by heat and pressure, releasing methane gas as a byproduct. CBM is typically located in coal seams that are relatively shallow, between 500 and 3,500 feet underground. CBM extraction involves drilling wells into the coal seams and using various techniques such as hydraulic fracturing or dewatering to release the methane gas. This gas can then be captured and used as a clean energy source for heating, electricity generation, or other industrial purposes. Research in the area of coalbed methane focuses on optimizing extraction techniques, understanding the geology and characteristics of coal seams, assessing environmental impacts, and exploring new potential reservoirs for CBM extraction. This research is important for increasing the efficiency and sustainability of CBM production and reducing its environmental footprint.
