From The Bismarck Tribune, nothing new for regular readers of the blog: new technology could recover more oil from early Bakken wells. Data points:
- re-fracks
- targeting wells drilled between 2008 and 2010
- industry says currently recovery 5 to 15% of OOIP
- 140 wells in the Bakken have already been re-fracked
- generally, to be economical, re-fracking needs to produce an additional 200K to 250K of crude oil
- not all areas amenable to re-fracking
Comments:
- about 2,500 wells drilled per year back in 2008 - 2010
- economical at what price? $25/bbl? $50/bbl? $100/bbl?
- when we first started blogging, the "word on the street" was that Bakken operators were recovering 1 - 3%; then Whiting made headlines when they suggested as much as 8%, and said they were targeting a much higher rate of recover
- I've never seen a figure as high as a 15% recovery rate in the Bakken
- Lynn Helms has said, in the past, what each 1% increase in recovery means in the Bakken
- if primary recovery rate goes from 3% to 6% -- that is a doubling of production
