Deconvolution of Multiwell Test Data

Abstract The deconvolution analysis technique that evolved with development of the deconvolution algorithms by von Schroeter et al.1 and Levitan et al.2, 3 became a useful addition to the suite of techniques used in well test analysis. This deconvolution algorithm, however, is limited to the pressure and rate data that originate from a single active well on the structure. It is ideally suited for analysis of the data from exploration and appraisal well tests. The above mentioned deconvolution algorithm can not be used with the data that are acquired during startup and early field development that normally involve several producing wells. The paper describes a generalization of deconvolution to multi-well pressure and rate data. Several approaches and ideas for multi-well deconvolution are investigated and evaluated. The paper presents the results of this investigation and demonstrates performance of the deconvolution algorithm on synthetic multi-well test data.
