Bakken Sweet Spots Are Petering Out

November 27, 2014

Bakken Sweet Spots Are Petering Out.

The Bakken, as well as other shale oil areas, is not one homogeneous area where equal amounts of oil can be found. David Hughes in DRILLING DEEPER puts it this way, though here he is talking about gas wells, the same applies to oil wells:

All shale gas plays invariably have “core” areas or “sweet spots”, where individual well production is highest and hence the economics are best. Sweet spots are targeted and drilled off early in a play’s lifecycle, leaving lesser quality rock to be drilled as the play matures (requiring higher gas prices to be economic); thus the number of wells required to offset field decline inevitably increases with time.

However the Bakken, at least through the September North Dakota Industrial Commission production report, has given no real indication that the Bakken is even close to peaking. But a closer look at the data makes me believe that is all about to change.

Growth in Global Total Debt sustained a High Oil Price and delayed the Bakken “Red Queen” | FRACTIONAL FLOW

November 3, 2014

Growth in Global Total Debt sustained a High Oil Price and delayed the Bakken “Red Queen” | FRACTIONAL FLOW.

The saying is that hindsight (always) provides 20/20 vision.

In this post I present a retrospective look at my prediction from 2012 published on The Oil Drum (The “Red Queen” series) where I predicted that Light Tight Oil (LTO) extraction from Bakken in North Dakota would not move much above 0.7 Mb/d.

  • Profitable drilling in Bakken for LTO extraction has been, is and will continue to be dependent on an oil price above a certain threshold, now about $68/Bbl at the wellhead (or around $80/Bbl [WTI]) on a point forward basis.
    (The profitability threshold depends on the individual well’s productivity and companies’ return requirements.)
  • Complete analysis of developments to LTO extraction should encompass the resilience of the oil companies’ balance sheets and their return requirements.
