Cleat development in coals of the Upper Cretaceous Mesaverde Formation, Pilot Butte area, Wind River Reservation, Wyoming
The cleat system developed in low-rank (mean viltrinite reflectance of 0.43 to 0.5 percent) coal beds in the Upper Cretaceous Mesaverde Formation was studied in outcrop and in coreholes drilled for coalbed methane evaluation near Pilot Butte in the central part of the Wind River Reservation. Cleats are the principal permeability pathway for fluids in coal beds. As a result, coalbed gas cannot be e

Coalbed methane potential of the Upper Cretaceous Mesaverde and Meeteetse formations, Wind River Reservation, Wyoming
The environments of deposition of the uppermost part of the Cody Shale and the Mesaverde and Meeteetse Formations of Late Cretaceous age were studied on outcrop in the Shotgun Butte area in the north-central part of the Wind River Reservation. A shoreface sandstone occurs in the lower part of the Mesaverde Formation at all localities studied, and is directly overlain by a coaly interval. Repetitiv

Occurrence and geochemistry of natural gases, Piceance Basin, northwest Colorado
The Piceance basin is a hydrocarbon-rich province that has natural gas production from reservoirs ranging in age from Late Jurassic to Eocene and large undeveloped resources of natural gas in coal beds and tight sandstone reservoirs of Cretaceous age. Gases from all producing intervals are of predominantly thermal origin and become isotopically heavier (delta isotope{13}C[1]: -51.3 to -29.1 o/oo)
