Companies fracking North Dakota wells recover more oil
June 11, 2017
BISMARCK, N.D. (AP) — Oil industry leaders say applying new hydraulic fracturing techniques to older wells in North Dakota's Bakken oil patch 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 technology advanced, The Bismarck Tribune (http://bit.ly/2rS9WAV ) reported. The energy industry uses hydraulic fracturing, or fracking, to extract oil and gas from rock by injecting high-pressure mixtures of water, sand or gravel and chemicals.
