Abstract

A comprehensive, integrated study of the reserve and production potential of the Barnett shale integrates engineering, geology, and economics into a numerical model that allows for scenario testing based on several technical and economic parameters. Implicit in RF analysis is an assumption about the shape and orientation of the drainage area. A plot of horizontal well EUR vs. well orientation for all wells clearly shows a minimum at NE 55° azimuth, indicating the prevailing principal horizontal stress direction in which fractures most readily propagate. The EURs of every well were determined with linear transient-flow decline equations and including the dampening effect of interfracture interference assumed beyond Year 8. An average production profile for a 4,000-ft horizontal well was developed for each tier based on historical data from wells in that tier. The study's production model includes the effect of historical attrition rates, which were found to increase as the rock-quality tier decreased.
