Design of an Algorithm for Deconvolving Pressure Derivative data During Wellbore Storage Diseño de un algoritmo para deconvolver datos de presión durante almacenamiento de pozo

Abstract

This article presents the process of designing an algorithm for deconvolved pressure derivative, which eliminates the effect of storage and indicates the radial flow behavior. The design is based on iterative deconvolution method proposed by Jansson (1984). In the validation of the algorithm, we have found that works even on data sets consisting of pressure versus time. However, there is an error, when used with inconsistent data. Acertain degree of inconsistency is normally present in real test data.
