The study looked at how coalbed methane wells in a specific area of China release gas when pressure drops during extraction. They found that factors like water levels, coal thickness, and gas content affect how much gas is released. The speed at which water is removed and the amount of water produced before gas affects the gas pressure the most. The original pressure in the reservoir also plays a big role in how much gas is released. These findings help understand how to control gas production in coalbed methane wells.
