For any injection falloff test to be conducted successfully a clean connection between the wellbore and the created fracture is needed The main objective of an in situ stress test and the minifracture test is to determine the pressure in the fracture when the fracture is open and the pressure when the fracture is Traditionally either an injection test or production test was applied to coal bed seams In this paper we present a new approach that combines injection and buildup testing In this paper we present a new approach that combines injection and buildup testing
