Deconvolution of Multiwell Test Data

TLDR

Deconvolution analysis, developed by von Schroeter et al. and later refined by Levitan and colleagues, is a well‑test technique traditionally limited to single‑well pressure and rate data and thus unsuitable for startup or early field development involving multiple producing wells. This paper generalizes deconvolution to handle multiwell pressure and rate data. The authors investigate and evaluate several approaches for multiwell deconvolution.

Abstract

Summary The deconvolution analysis technique that evolved with development of the deconvolution algorithms by von Schroeter et al. (2004), Levitan (2005), and Levitan et al. (2006) 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 previously 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 mul-tiwell pressure and rate data. Several approaches and ideas for multiwell deconvolution are investigated and evaluated. The paper presents the results of this investigation and demonstrates performance of the deconvolution algorithm on synthetic multiwell test data.
