New technology could recover more oil from early Bakken wells

12 Jun 2017   Shale Oil

Oil companies are applying new hydraulic fracturing techniques to early Bakken wells, a process industry leaders say has the potential to recover more oil without increasing the footprint on the land. Operators are targeting wells drilled between 2008 and 2010, the early years of Bakken development before fracking technology advanced to where it is today. Companies are refracturing the older wells using today’s technology and getting promising results, said Justin Kringstad, director of the North Dakota Pipeline Authority, who recently analyzed the wells. “On average, they’re getting better performance from the wells,” Kringstad said. Fracking — or pumping a high-pressure mixture of water, sand and chemicals deep underground — and horizontal drilling techniques allowed operators to recover oil from the Bakken. But the industry believes it’s only recovering about 5 to 15 percent of the oil available, Kringstad said. More than 140 wells in the Bakken have been refractured, […]
