The Tangsrud Wells

Updates

November 27, 2021: in the original post, the name of two wells were "Dolphin." A reader suggests that "the Continental Resources 'Dolphin play'" was (one of) the original locations Harold Hamm first bought into the Bakken forty years ago to see what the Bakken might yield. 

November 27, 2021: This is a lousy well. Does CLR have something in mind for this well?

CLR's Tangsrud wells. Fourteen CLR Tangsrud wells in one 1280-spacing unit as of original post, September 20, 2013.

Up in Hayland oil field, far northwest corner of North Dakota, southeast corner of Divide County.

Later, "No oil shows were noted at the shaker while drilling the Tangsrud horizontal. Total gas reading were low (50- 60 units (100 units = 1% methane in air). No sample shows were noted while drilling the Tangsrud lateral....some very porosity was noted in the dolomite."; t1/14; cum 38K 7/17;

He continued, "The daily footage was phenomenal and averaged around 2,400 feet per day; drilling was maintained almost entirely within the target zone. The proximity throughout the well to the target zone should make for a productive fracking operation; t2/14; cum 44K 7/17;
