Western Cretaceous Coal Seam Project. Summary of the Cooperative Research Well FCFederal No. 12 Operated by Mesa Operating Limited Partnership. Topical Report, January 1988-February 1992

摘要

The FC Federal Number 12 well is located approximately 20 miles south of the highproductivity Meridian 400 development of the San Juan Basin Fruitland formation in an area that was believed to have a coal in the high volatile C bituminous area of the basin. The well was cored, logged, and drill stem tested to obtain estimates of reservoir properties. The combination of modest gas content (215 SCF/Ton), low gas diffusion rates, and very low natural fracture system permeability (less than 0.01 md) combined to make the reservoir properties sub-commercial at this location. The results confirmed the predictions made by GRI researchers at the Texas Bureau of Economic Geology. Hydraulic fracture stimulation did not result in commercial gas production rates due to the lack of permeability development.
