No history exists for the understanding required to make predictions on how much oil will be mined from shale basins. this information is very important as the first thrust of drilling was to secure mineral rights, this was done with very long laterals at single depths. Now we are moving to manufacturing phase where operators will shrink acreage, and begin tapping multiple layers of laid in resources at different depths, all from a single pad. Standards of efficiency will be set during this next phase of development. One of the first examples is contained in the below information. What this information tells the observer is that predictions about oil in place, costs to recover, and optimum rates of return on capital have been woefully inadequate due to misunderstanding the nature and practice of recovery of nucleated oil particulants from shale zones laid in at different times. Projections from agencies and even companies lacking understanding of the holistic system are worthless in the face of new facts. LHN5 offered this quote by Carl Sagan, at Ahhas thread which aptly applies to the subject of Peak oil; “One of the saddest lessons of history is this: If we've been bamboozled long enough, we tend to reject any evidence of the bamboozle. We're no longer interested in finding out the truth. The bamboozle has captured us. It is simply too painful to acknowledge - even to ourselves - that we've been so credulous. So the old bamboozles tend to persist as the new bamboozles rise.” From The June, 2013, Hearing Dockets; Highlights: CLR Considering 17 Wells On A 640-Acre Spacing Unit In the better Bakken, we are starting to see well densities from the norm of 8 wells per 1280-acre spacing unit to 10 wells. Notice the increased density on some 640-acre spacing units.
