Analysis of eastern Devonian gas shales production data. Final report, July 1984-May 1987
This report summarizes the final results, conclusions, and recommendations from a study of well-test and production data from over 1600 Devonian Shale gas wells. The key accomplishment of the study was the development of a number of new analytical tools for well test and production data analysis including (1) an analytical production data analysis model, (2) an analytical well test analysis model, (3) an automatic history matching algorithm, (4) a set of production data anlysis type curves, and (5) the SUGARIII reservoir simulator. Although developed primarily for analyzing data from Devonian Shale gas wells, these tools are generally applicable to the analysis of well test and production data from a variety of reservoirs. From a systematic analysis of long-term production data, the permeability-thickness product was found to be the only reservoir property which can be accurately and uniquely determined from history-matching production data. Gas in place can also be determined provided that sufficient production data are available. Empirical equations were developed for predicting well performance from kh and GIP and from past production data when available.
