An Algorithm for Determining Smooth, Continuous Pressure Derivatives From Well-Test Data Academic Article uri icon

abstract

  • Summary An algorithm for determining pressure-derivative functions from measured well-test data is presented. The pressure data are fit with a spline function that can account for curve shape constraints. The first and second derivatives of the resulting spline function are calculated analytically and can be used for type-curve matching. Two examples illustrate the performance of the algorithm.
