Abstract: Divide Creek Gas Field: Example of an Ecological Approach to Energy Development

Melody R. Holm, Gary T. Osier

The Divide Creek Gas field is in a Federal unit of 25,746 acres, consisting primarily of lands in the White River National Forest of northwestern Colorado. Original development by Sun Oil Company between 1955 and 1962 was in the Cozzette and Corcoran sandstones of the Cretaceous Mesaverde Group. In 1989, Oryx Energy Company (formerly Sun Oil) embarked on an 11-well drilling program to develop coalbed gas resources from Cretaceous Mesaverde Cameo coals. The approach the Forest Service and Oryx took in the coalbed gas development program illustrates an ecological approach to energy development.

Rugged topography, variable and often severe climate, high susceptibility to slope failure and erosion, low capacity for revegetation, a large variety of vegetation types, and critical habitat for wildlife characterize the area. Surface disturbance in such areas can lead to a chain reaction of negative effects on vegetation and wildlife and ultimately on human use. However, good communication and cooperation among agencies and the operator led to well-planned and carefully constructed roads and well sites during the latest phase of development. A reconstructed section of road and several new well sites provide examples of techniques used to minimize surface disturbance and potential for erosion. Design of the gathering system and pads illustrates ways in which accidental spills can be contained and damage from such can be minimized. Significant problems with erosion or mass wasting in the field have not occurred, and visual quality, along with the health and diversity of water resources, plant communities, wildlife, and opportunities for human use is sustained.
