Fracture evaluation with pressure transient tests in low-permeability gas reservoirs. Part II: field examples. Academic Article uri icon


  • In this paper field examples are presented which illustrate the use of the different analysis techniques for determining the in situ reservoir and fracture parameters. In addition, a single phase two dimensional, finite difference reservoir model has been used to history match all of the well tests. With the reservoir model it is possible to simulate variations in fracture conductivity, non-Darcy flow, flow rate changes, wellbore storage, gas compressibility gradients, gas viscosity gradients and other parameters which can complicate the analysis of field data. The finite difference history match analysis normally provides a more realistic reservoir description which can be used to evaluate the various 'hand' calculation analysis techniques.
