The company, which has completed 21 new wells in 2010, has 25 wells under or awaiting completion.

Questar drilled a 14,165-ft directional well from spud to TD in 12.8 days in the first quarter of 2010 compared with the prior Pinedale record of 13 days in the 2009 fourth quarter. Completed well cost now averages less than $4.5 million.

Questar E&P has a 60% working interest in its operated Pinedale acreage.
