CASPER – The Bureau of Land Management is seeking public comments on a proposal by Encana Oil & Gas to drill 85 new natural-gas wells adjacent to the Jonah Field in western Wyoming.

The new production area would be about 70 miles northwest of Rock Springs, with an average density of one well per 80 acres and a maximum density of one well per 40 acres, the BLM said. The project would also include support facilities such as access roads, pipelines and compressor stations.

CHEYENNE — Gov. Dave Freudenthal asked the U.S. Forest Service on Thursday to delay acting on a proposal to drill for natural gas in the Wyoming Range, a popular hunting and recreation area within the Bridger-Teton National Forest.

Houston-based Plains Exploration and Production Co. wants to drill 136 gas wells on 17 well pads spread over about 10,000 acres on the northeast corner of the Wyoming Range. Some of the acreage is near a rural subdivision of expensive homes and cabins.

The Forest Service says the Plains Exploration plan would disturb about 400 acres and result in building about 15 miles of roads.

“In a historical context, such a proposal is quite modest,” Freudenthal said in a letter to the Forest Service. “In the Wyoming Range, this proposal is monumental, far reaching and fraught with controversy.”

Wyoming ended 20 years of declining oil production in 2005 with the help of a major CO2 flooding project at the Salt Creek oil field in the southern Powder River Basin. In enhanced oil recovery, alternate flows of water and CO2 are pumped into an oil reservoir, sweeping additional volumes of oil to production wells.

With the high price of oil, many Wyoming producers are eager to use enhanced oil recovery methods such as water flooding and CO2 injection to revitalize old oil fields. Most older oil fields still have significant reserves that were not attainable through primary recovery methods.

In 2005, about 8.5 percent of Wyoming’s total oil production came from enhanced oil recovery using CO2 injection, according to the Wyoming Enhanced Oil Recovery Institute.

An estimated 8 million barrels of oil remain in Wyoming, of which up to 15 percent can be recovered using various enhanced oil recovery methods, according to the Wyoming State Geological Survey.
