Barrons this weekendBarrons did a small update on the US Bakken plays. Commented on how they were all up close to 100% or more. They also reported that a well was drilled below the middle Bakken formation and was flowing close to 700 barrels per day.
If this well is not a fluke you can double the value of all productive Bakken areas.
Another reason to hold on to your Petrobank, Panterra, etc.
From Wikipedia -
The rock formation consists of three members: lower shale, middle dolomite, and upper shale. The shales were deposited in relatively deep marine conditions, and the dolomite was deposited as a coastal carbonate bank during a time of shallower water. The middle dolomite member is the principal oil reservoir, roughly two miles (3.2 km) below the surface. Both the upper and lower shale members are organic-rich marine shale.
