A semi-analytical model for flow regime diagnosis in multi-fractured horizontal wells within deep coalbed methane reservoirs

Abstract Since 2021, significant advances have been made in the exploitation of deep coalbed methane (CBM) in China, with peak gas production rates reaching over 100,000 m3/d from wells in the Ordos basin. Despite these successes, research on gas flow mechanisms and transient pressure behavior, part...
