IMPROVED TECHNIQUE FOR ESTIMATING PERMEABILITY, FRACTURE LENGTH AND FRACTURE CONDUCTIVITY FROM PRESSURE BUILDUP TESTS IN LOW PERMEABILITY GAS WELLS. Academic Article uri icon

abstract

  • To optimize the development of low permeability gas reservoirs, long hydraulic fractures are normally required. When developing a low permeability reservoir, it is imperative that the post-fracture performance of each well be analyzed to determine the effectiveness of the hydraulic fracture. The objectives of this paper are: (1) to review briefly the limitations of existing analysis techniques, and (2) to introduce a new technique which should prove useful for analyzing pressure buildup data from wells containing a finite conductivity vertical fracture. An analysis technique proposed by the authors for short-duration pressure buildup tests is discussed. This technique attempts to give accurate estimates of fracture half-length, fracture conductivity, and formation permeability.
