Scope

This standard specifies the technical content such as the design of injection/pressure drop test wells for coalbed methane wells, instrumentation and equipment, construction procedures, data collection, data interpretation, and test well reports.
This standard is applicable to tests conducted during the drilling process or after completion of coalbed methane wells. The aim is to obtain parameters such as coalbed permeability, reservoir pressure, skin factor, detection radius, and in-situ stress.
