| Abstract: | An algorithm called smooth spline filter is presented to pre-processing a set of measured pressure data. It can be obtained smooth, continuous pressure derivative functions from processed well-test data. It can be used for type curve matching. This method reduces computing complexity and promotes identification efficiency. From experience with thousands of well tests, we have chosen several examples to illustrate the need for pre-processing the data. The examples show that smooth spline filter method is effective and practical. |
