Description

Subsurface data and methane potential from two holes (Southern Ute/Department of Energy Coalbed Methane Test Wells) drilled in 1982 in the San Juan Basin. 21 pages. 7 figures. 14 tables. Digital PDF download. OF-82-04D

The two Southern Ute/Department of Energy test wells are located in the north-central portion of the San Juan Basin, Colorado, on the Southern Ute Indian Reservation. The Southern Ute Indian Reservation is a parcel measuring about 15 miles north-south and 72 miles east-west, bounded on the south by the Colorado-New Mexico state line. The two project wells are located on the Oxford Tract, approximately three miles northwest of Ignacio, Colorado.

The target horizon on both project wells is the basal Fruitland Formation. The Upper Cretaceous Fruitland Formation is dominantly composed of carbonaceous shales, siltstones, sandstones and coals. At least two sources of gas are hosted in the Fruitland Formation, carbonaceous shales and coals. This report discusses the location with regional geology of the project site, the coal characteristics and petrography, desorption results, gas analyses, and well completion.
