| Abstract | Several methods have been presented in the literature for analyzing transient pressure data of fractured wells. We tested with some model studies based on the solutions to the 3D problem of multiple high-angle fractures (HAM) intersecting a wellbore. The model solutions representing transient pressure behavior of HAM fractures are defined in terms of 3D rectilinear coordinates. The HAM fracture model equations include the finite conductivity of the fractures, and our solutions reduce to previously published results for the special case of vertical fractures and/or infinite-conductivity fractures. A computer program, MULFRAC, has been provided to calculate the dimensionless drawdown at the wellbore. This paper shows the solutions of MULFRAC, some comparison of MULFRAC results with publishedspecialcases. |
