Coalbed Methane (CBM) is a high-quality unconventional energy resource. The successful development and utilization of a CBM resource needs to consider technical feasibility and economic viability. These factors are also necessary for the improvement of production safety in coal mines, reducing carbon emission, and optimizing energy structure. Because of its unique resource characteristics, surface drilling is the prevailing development approach all over the world. Directional and horizontal wells are generally the two major well-types for CBM development. Development well-type is an important factor affecting CBM efficient development, as it is a key factor in the process of the economic and effective development of CBM resource. In this paper, a method based on Unit Technical Cost (UTC) will be constructed from the perspective of economic viability, and will be used for more simple and accurate optimization of CBM. This method is used for practical well-type optimization in two major CBM development basins in China, and the application results prove that this method is scientifically accurate and feasible.
