Top Story of the Week? Bakken, North Dakota, USA

 A huge thank you to Gary for bringing this to my attention.

Go to the GIS map server and check out Tyrone field, or search for the "Clark" well in Tyrone field.

Oasis Petroleum has three wells in section 13-156-102.

18418, 1,228, Oasis, Sandaker 5602 11-13H, Wildcat, Bakken; s3/23/10; t6/2/10; 7/11 75K bbls
18567, 1,835, Oasis, Njos Federal 5602 11-13H, Tyrone Field, Bakken; s1/19/10; t6/18/10; 7/11 79K bbls
21261, 94, Oasis, Clark 5602 12-13H, came off confidential May 1, 2012; said to be economical by Oasis (personal correspondence); closed hole frack; 4 million lbs sand/ceramics; Lodgepole (not a Bakken)

Background:

Oasis was issued permits for the Njos and Sandaker back in late 2009/early 2010. Note the wildcat status for the Sandaker well.

There was no third well planned at that time. Oasis simply planned to do something standard: put two wells near each other, and drill a long horizontal north, and a long horizontal south.

As per standard procedure, the vertical portion of the well would be drilled into the Lodgepole, where the kickoff point to start angling the horizontal portion of the well would begin, with the middle Bakken as the target.

A surprising thing on the way to middle Bakken happened: promising oil show in the Lodgepole.

And so, shortly after drilling these two Bakken wells, Oasis applied for, and received another permit in the same area for a short lateral targeting Lodgepole. The two Bakken wells: 1280-acre spacing; the Lodgepole well: 640-acre spacing.

This could end up being very, very interesting.
