abstract
This paper presents methods for designing and analyzing prefracture and postfracture injection/falloff tests and multirate production tests in coalbed methane reservoirs. These tests should be conducted on selected wells in a coalbed methane pilot test. Pilot testing is the best way to evaluate the productive potential of coalbed methane reservoirs. A properly designed testing program can minimize the expense and maximize the reliability of estimating reservoir properties that are essential to a thorough evaluation of a coalbed methane reservoir.
