Secondary Natural Gas Recovery: Targeted Applications for Infield Reserve Growthin Midcontinent Reservoirs, Boonsville Field, Fort Worth Basin, Texas. Volume 2. Appendices. Topical Report, May 1, 1993-June 30, 1995

摘要

This assessment of Midcontinent sandstone natural gas reservoirs in Boonsvillefield integrated four key disciplines: geology, geophysics, reservoir engineering, and petrophysics. The entire Atoka Group (Lower and Upper) in the project area was divided into 13 third-order genetic stratigraphic sequences. To our knowledge, this is the first public, comprehensive genetic sequence analysis that relates these prolific Pennsylvanian gas reservoirs to their seismic response and to gas productivity. A 26 sq mi 3-D seismic survey was acquired and interpreted to test methods for delineating reservoirs in thin-bed, hard-rock environments. Reservoir facies frameworks, assessed by integrating geological and geophysical approaches, were combined with engineering and petrophysical evaluations of produced gas volumes and reservoir quality.
