Deconvolution method for pressure transient analysis Abu Gabra formation Case Study- Sudan

Abstract

Traditionally well testing is completed by analyzing transient pressure due to constant production rate. However, in the oil industry practice, engineer often has to deal with the transient pressure result from variable flowing rate history. This traditional and conventional well testing approach is still being used. However, a new well testing tool called Deconvolution was starting to receive much attention, and has been emerging as a new tool of analyzing test data in the form of constant rate drawdown response. In other words, it transforms variable rate and pressure data into constant rate pressure response. Deconvolution techniques is a useful addition method to the well test analysis. In this research, a brief introduction of conventional well test interpretation will be presented, followed deconvolution interpretation, and the results show that the deconvolution method can be applied on the drawdown period of single well test.
