Application Summary AI generated
This standard specifies the technical requirements and procedures for conducting drill stem testing (DST) in coalbed methane wells. It is applied in the coal mining and unconventional gas extraction industry to evaluate reservoir pressure, permeability, and fluid properties directly through the drill string. The method is used during exploration and development to assess gas production potential and guide well completion decisions.
