Since 1983, the Deep Coal Seam Project (DCSP) and the Western Cretaceous Coal Seam Project (WCCSP) of the Gas Research institute has funded research efforts in the Piceance and San Juan basins of Colorado and New Mexico to further the knowledge of all facets of commercial coalbed natural gas reservoir development. Because of WCCSP research into openhole completion well effectiveness in the Fruitland play, and the need to complete a successful Cameo coal openhole well, the South Shale Ridge [number sign]11-15 well was deemed to be an excellent chance for technology transfer and evaluation. Because of implementation of carefully designed air mist drilling and controlled openhole completion techniques, along with a sufficient magnitude of cleat permeability, it appears that the [number sign]11-15 well is commercial. The cavity was installed without major problems. The initial gas production test rate of roughly 280 MCFGPD is one of the best in South Shale Ridge. The [number sign]11-15 well case study is quite important in that it may serve to emphasize the point that the conservative attitude towards commercialization of previously untapped petroleum resources is often not correct. It is now an open question as to whether the conventional wisdom that most of the Cameo coal gas play is too tight to enable commercial production is indeed true, or if by analogy with Fruitland openhole wells, Cameo coal wells that have been hydraulic fracture stimulated are commonly very poorly connected to the cleat permeability of the reservoir. There is no significant reason to believe that the South Shale Ridge area is geologically unique, and thus there is a distinct possibility that more widespread Cameo coal production than has been previously recorded can be achieved.
