Coalbed Methane Production Model Based on Random Forests Optimized by a Genetic Algorithm

ACS Omega, 2022
It is of great significance to evaluate and predict coalbed methane (CBM) production for the exploitation and exploration of CBM. The flow characteristics of gas and water are very complicated and important in the process of CBM exploitation.
