the Bakken is the largest continuous reservoir of oil ever found in the US; light, sweet oil
after the 2013 USGS Survey, officials double the size of the Bakken/Three Forks: 7.3 billion bbls recoverable; could be as much as 11 billion bbls recoverable one trillion bbls of original oil in place (OOIP) -- other estimates
7,000 active wells in North Dakota; 980,000 bopd; 100 bopd/well (California with about 60,000 active wells); North Dakota #2 in US production, behind Texas
185 active rigs (range 180 - 195)
high density spacing; Oasis will drill 21 wells in one 640-acre section; 42 wells/1280-acre spacing in better Bakken
Middle Bakken; four benches in the Three Forks; the Three Forks will increase the OOIP estimates by about 60% (compared to the Middle Bakken only); the Three Forks through the Bakken, but seems to extend beyond the periphery of the middle Bakken prospect;Whiting tends to refer to the upper Three Forks in its northern ops area as the Sanish; Whiting tends to refer to the upper Three Forks in its southern ops area as the Pronghorn Sand
fracking a new well improves production of a neighboring, existing well ("halo effect")
