Measurement of dynamic reservoir conditions, Volume 2: Final report
US Steel's Southern Appalachian Field Office conducted a study to determine if a relationship existed between structure and coal seam gas production. The study consisted of mapping surface joints, tracing linears, and evaluating gas and water production from US Steel's Oak Grove Coal Degasification Field. Gas production within the Oak Grove Field shows ''high'' production in the east and central portions of the field. Production outside the ''high'' gas producing zones appears to be a function of original gas content and/or in-place methane content. Production within the ''high'' zones appears to be related to a set of east-west trending joints associated with the eastern boundary fault of Oak Grove Mine. These joints are believed to increase production by increasing gas contributions from adjacent seams and/or increasing the permeability of the coal seam. If all other factors (depth, gas content, and coal thickness) are approximately equal, substantial increases in gas production can likely be achieved by locating coal degasification wells in areas of dense jointing associated with normal faults.
