Whiting credits completion design changes for production rise

By Luke Geiver | July 31, 2013

Whiting Petroleum Corp.’s production in the western area of the Williston Basin grew by 231 percent year-over-year, the Denver-based exploration and production company said in its second quarter earnings release. The success is linked to completion design changes used at Whiting’s Missouri Breaks formation. According to the company, the practice of using cemented liners and higher sand volumes has significantly improved production rates. 

“We recently completed the Weber 24-30-1H flowing at a rate of 1,164 bopd, using our new completion design. This well offset the Mullin 21-24-1H, which tested at a rate of 481 bopd, and was completed using our prior frac design, an uncemented liner with sliding sleeve technology,” the company noted. 

In the Southern Williston Basin, production averaged out at 13,325 bopd. “We have been shifting to pad drilling in the Pronghorn area in the first half of 2013 and have generated a backlog of uncompleted wells,” the company said. There are currently 13 wells in the region waiting on completion or being completed. 

In the Sanish Field area, Whiting recorded an average production of 36,315 bopd in the second quarter compared to 35,805 bopd during the first quarter. “The increase was in part attributable to a higher density drilling program at the Parshall field. We have initiated our higher density pilot project in the Sanish field. If successful,” the company added, “this could add 191 gross well locations.”
