Development Trend of Deconvolution Method to Analysis of Well Test

Deconvolution transforms variable rate pressure data into a constant rate initial draw down with duration equal to the total duration of test .This paper has presented for main benefit of deconvolution that is the increasing of the radius of investigation which allows seeing boundaries and connectivity not visible in individual flow periods. In this work, we have compared the results between convolution and deconvolution outputs by using Feket F.A.S.T well test software. deconvolution offers a viable tool for well-test and production data analysis. It is hoped that this paper will encourage well test interpreters to use deconvolution confidently as part of the well test analysis process.
