Analysis of production characteristics and engineering measures for deep coalbed methane wells in the Ordos Basin

Iraqi Journal of Chemical and Petroleum Engineering
   Given the significant differences in gas accumulation modes, coal reservoir characteristics, and gas preservation conditions for ultra-deep coalbed methane (vertical depth > 3000 m, measured depth > 5000 m), their production characteristics, flowback
