Deconvolution for Pressure-interfered Production Data of Multiple Shale Gas Wells Containing Sorption Characteristics

Abstract

When analyzing the production data acquired from multiple shale gas wells, it is essential to remove pressure interference for obtaining correct reservoir characteristics. In this study, we employed deconvolution process to remove pressure interferences, however, it cannot be applied directly to shale gas data due to the nonlinearity occurred from desorption. Therefore, we propose new deconvolution method implemented by sorption-corrected pseudopressure to make linearization of pressure-rate relationship. With linearized production data, the results show that the proposed method enables to remove pressure interference effect of multiple fractured wells. Ultimately, one can analyze production data to obtain correct reservoir characteristics. © Copyright 2016 by the International Society of Offshore and Polar Engineers (ISOPE).
