FRACTURE EVALUATION WITH PRESSURE TRANSIENT TESTING IN LOW-PERMEABILITY GAS RESERVOIRS - 1. THEORETICAL BACKGROUND. Conference Paper uri icon

abstract

  • The purpose of this paper is to summarize the theoretical background of methods which the authors have attempted to use to determine formation permeability, fracture length, and fracture conductivity in low-permeability, hydraulically fractured gas reservoirs. Test analysis methods discussed here include (1) a method applicable only after a pseudo-radial flow pattern is developed in the reservoir, (2) a method applicable when linear flow dominates in the reservoir, (3) published type curves, with emphasis on those which include finite-conductivity fractures, (4) a modification of linear-flow techniques useful for finite-conductivity fractures, and (5) use of finite-difference reservoir simulators in a history-matching mode.
