This work presents the development; validation; and application of a deconvolution method that uses B-splines to analyze variable-rate reservoir-performance data. Variable-rate deconvolution is a mathematically unstable problem. B-splines represent the derivative of unknown unit-rate drawdown pressure; and numerical inversion of the Laplace transform is used in this formulation. When significant errors and inconsistencies exist in the data functions; direct and indirect regularization methods are used (i.e; mathematical uniformity processes). The new deconvolution method has broad applicability in variable-rate/pressure problems and can be implemented in typical well-test and production data analysis;
