The following SPE publications provide theoretical foundation for some specific capabilities implemented in Convolution Explorer application.  The first reference is the first publication in the industry on multi-well deconvolution.  It defines multi-well deconvolution problem, presents its formulation and demonstrates that the problem can be solved provided that analysed multi-well data have appropriate information content. The second reference presents implementation of material balance pseudo-time transform within the context of pressure transient analysis:  

• SPE-102484. Deconvolution of Multiwell Test Data.   Michael M. Levitan.  SPE Journal. December 2007.
• SPE-134261. Deconvolution of Pressure and Rate Data From Gas Reservoirs With Significant Pressure Depletion.   M.M. Levitan, M.R. Wilson.  SPE Journal. September 2012.

The following document A Common Framework for Analysis of Well Test and Surveillance Pressure and Rate Data. Provides an introduction to the analysis approach implemented in Convolution Explorer. 

The following three-part series of notes provides an introduction of the analysis capabilities offered by Convolution Explorer application:

• Part 1. Reservoir Dynamic Analysis.  High-level overview of Pressure Transient Analysis and additional capabilities required for analysis of long-term surveillance pressure and rate data. 
• Part 2. Example of Dynamic Analysis Workflow Using Convolution Explorer Application.  Will help you to get familiar with the analysis capabilities implemented in Convolution Explore. This document presents an analysis workflow one could follow when working with the application.  The input file for this analysis example is "3.PermGauge-gas.txt".  You can download this input file and try to repeat this analysis on your own.
• Part 3. Integration of Reservoir Simulation in Analysis Workflow.  Demonstrates incorporation of geologic and seismic information in a form of reservoir map in analysis workflow through use of Response Generator simulation module in Convolution Explorer Application.

The following SPE publications present examples of reservoir dynamic analysis of multi-well surveillance data using Convolution Explorer application:
