The Tangsrud Wells

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.
  • 24967, 197, CLR, Tangsrud 9-1H, Hayland, middle Bakken, no frack data; t10/13; cum 68K 7/17; 
  • 24966, 52, CLR, Tangsrud 10-1H2, Hayland, t3/15; 47K 7/17;
  • 24965, 537, CLR, Tangsrud 5-1H, Hayland, t4/14; cum 63K 7/17; 2
  • 24964, 390, CLR, Tangsrud 6-1H2, Hayland, t10/13; cum 46K 7/17; 
  • 24936, 360, CLR, Tangsrud 8-1H1, Hayland, t10/13; cum 69K 7/17;
  • 24935, 216, CLR, Tangsrud 7-1H3, Hayland, t10/13; cum 40K 7/17;
  • 24934, 76, CLR, Tangsrud 4-1H3, Hayland, "the Tangsrud is an attempt in the area to establish oil production from the 3rd bench of the Three Forks (within the lower half of the formation; identified by the North Dakota Geological Survey as "Member 2")." 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;
  • 24931, 514, CLR, Tangsrud 14-1H, Hayland, t10/13; cum 50K 7/17;
  • 24930, 545, CLR, Tangsrud 13-1H2, Hayland, t2/14; cum 51K 7/17;
  • 24929, 995, CLR, Tangsrud 12-1H3, Hayland,on a 6-well Eco-Pad; TF 3; vertical depth and curve were drilled; then drilling paused for the drilling of #24928, #24966, and #24967; gas units very, very low (25 to 29) in TF3; even the geologist commented that "overall the well had very poor gas shows while drilling." 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;
  • 24928, 344, CLR, Tangsrud 11-1H1, Hayland, t2/14; cum 50K 7/17;
  • 24924, 168, CLR, Tangsrud 3-1H2, Hayland, t1/14; cum 59K 7/17;
  • 19107, 488, CLR, Tangsrud 2-1H, Dolphin, t11/10; cum 115K 7/17; 24 stages; 2.8 million lbs sand/ceramic; middle Bakken;
  • 17649, 922, CLR, Tangsrud 1-1H, Dolphin, t7/09; cum 141K 7/17;
  • 10210, 16/33, Bakken/Madison; 16/33; Condor Petroleum, Tangsrud 12-1, t12/03; t10/83; cum 24K 7/17; cum 134K 7/13; the Madison last produced in 2006; the Bakken remains barely active; a vertical well; no directional, no horizontal
