Nice Discussion of Three Wells Over Time -- Bakken, North Dakota, USA

For newbies, this is a nice discussion about three wells in one 1280-acre spacing unit drilled over the past three years, and the effect fracking has on results.
  • 15787, no IP reported, Angela Kaye 2-11H, Murex, West Bank, Bakken, no test date; first production September, 2005; cum 217K 10/12; 
  • 18551, 1,250, Murex, Kristi Leigh 11-2H, West Bank, Bakken, t5/10; cum 192K 10/12
  • 19196, 2,395, Murex, Ventura 11-2H, West Bank, Bakken, t11/10; cum 133K 10/12;
All three wells were horizontals in sections 2-11, T156N-R96W.

The wells are about 2.5 miles southwest of Tioga (Iroquois for "Peaceful Valley"), in the Beaver Lodge oil field, literally where the oil industry got its start in North Dakota.
The spark that ignited North Dakota's oil boom of 1951 was discovery of oil by Hess Petroleum Corporation on the Clarence Iverson farm, 8 miles south of Tioga.

Location of the Clarence Iverson #1 well: just east of Country Road 21 about eight miles south of Tioga in the SW4 SW4 section 6, T155N-R95W. "X Marks the Spot." [These links are broken; I will try to find them later.]
  • 25, Lease Name: Clarence Iverson, #1; Beaver Lodge-Devonian Unit G-307, t4/4/51 (Silurian); t12/17/51 (Madison); 9/27/59 (Devonian); all PNA now; the Devonian last produced in 1977; and was still producing over 1,000 bbls/month, better than some Bakken wells after two years of production; 
Note: for record keeping. The first well drilled in the West Bank oil field was the Stacy-Lynne.
