Whiting Petroleum Corp. has proven a new completion design for the Williston Basin. “This is an exciting time for Whiting and our shareholders,” said James Volker, Whiting’s chairman and CEO. During the company’s third-quarter investors call, Volker explained that the Denver-based exploration and production firm has found great success using a cemented liner, plug and perf completion technique in its recent Williston Basin wells.

The design utilizes cemented liners and higher volumes of frack sand. Cemented liners encase the horizontal section of the wellbore creating better stability and control of fracture initiation. “The new frack design appears to significantly improve production rates,” the company said. In August, Whiting completed the Sundheim 21-27-1H well using the new approach. The initial production rate of the well was 75 percent better than the offset well completed by another operator using a different technology, according to Whiting.

In its Missouri Breaks acreage area, the last eight wells were completed using the new fracture approach. Results of the wells show a 60 percent or better production increase over the previous 31 wells in the same area completed using uncemented liners and sliding sleeves.

In its Hidden Bench Prospect, Whiting reported results from two different wells. For the well completed using the cemented liner approach, the IP rate totaled 3,795 barrels of oil per day. For the well completed using an uncemented liner, the IP rate reached only 2,715 bopd. Both wells were completed on October 1, 2013. “Our new completion design using cemented liners and plug and perf technology is working throughout the Williston Basin,” Volker said.

In its Southern Williston Basin acreage, the company also said it is testing the potential to drill six or seven wells per drilling spacing unit versus a prior plan that would only drill three wells per spacing unit.
