Analysis of Production from Tight Gas Formations. Volume 1. Report of the Analysis

摘要

The Strategic Analysis and Energy Forecasting Division of the Gas Research Institute commissioned the study. Its objectives were to determine the amount of tight gas produced over recent history, estimate the ultimate recovery and remaining proved reserves associated with the production, and provide quantitative descriptions of the fields currently producing tight gas. While separate volumes provide these data at various levels of disaggregation (PGC Region, FERC designation, and individual fields), the report describes the overall results. Data limitations constrained the scope of the present study to the tight sandstone formations of the Western and Southwestern U.S., which account for 80% or more of tight production to date. However, an estimate of Eastern U.S. tight gas production (which includes an indeterminate proportion from Devonian Shales, considered by many to be tight) has been included to provide a national perspective.
