Black Hills Energy will be conducting maintenance on two storage wells at its Wolf Creek natural gas storage field south of Glenwood Springs later this month.

Several pieces of equipment, including a workover rig, will be brought to the site once snow has melted and the roads through Four Mile Park and up to the storage field site are dry for transport.

An increase of truck traffic on Four Mile Road and Forest Road 300 is anticipated during the work, but should have minimal impacts to the public, according to a press release from the Denver-based company.

The scheduled work will be done as conditions permit, but is expected to begin by next week. Maintenance activities, including downhole well inspections and maintenance, are expected to last 30 days, the release said.

“Black Hills Energy operates seven wells in the storage field, and is committed to operating the field safely and responsibly in the ecologically diverse area in which it is located,” it stated.

The procedures include the use of technologically advanced equipment, constant monitoring, routine maintenance and regular testing of the system, it said, adding that the measures are in accordance with pending Department of Pipeline & Hazardous Materials Safety Administration (PHMSA) rules.

Maintenance work is to take place at existing well sites and will not impact the surrounding U.S. Forest lands or the ability of the public to recreate and access the area.

The public is also advised to not approach any of the storage facilities or maintenance equipment.

The Wolf Creek Storage Field is a depleted gas field that is now used as underground natural gas storage to serve Black Hills Energy customers in the Roaring Fork and Eagle valleys.

Natural gas is injected into the field during the summer and extracted during high demand winter months for use by natural gas customers in the region.
