Ten (10) New Permits -- The Williston Basin, North Dakota, USA; XTO Reports A Nice Well

Active rigs: 185 (steady)

Ten (10) new permits --
  • Operators: Abraxas (4), Triangle (3), OXY USA, Stephens Production, EOG,
  • Fields: Manning (Dunn), Parshall (Mountrail), Pershing (McKenzie), Antelope Creek (McKenzie),
  • Comments: This is Stephens' first well in North Dakota; the well will be about 12 miles almost directly north of Minot, a wildcat: Matson 3-1.
The results of the wells I had coming off the confidential list today were not posted for some reason.

Two producing wells were completed:
  • 23287, 844, Hess, AN-Bohmbach 153-94-2734H-2, Antelope, Three Forks/Sanish, t4/13; cum-
  • 23470, 1,551, XTO, Lawlar 41-15SH, North Tobacco Garden, t4/13; cum --
It's interesting Hess refers to the Bohmbach well as a "Sanish" well. I've generally considered the "Sanish" limited to Whiting's wells in the Sanish oil field. The "Sanish" in this area is closely associated with the Three Forks.  The USGS 2013 Survey states: "The Pronghorn Member (formerly known as "Sanish sand")"; and, "The Pronghorn Member of the Bakken Formation, although geologically and stratigraphically defined as part of the Bakken Formation (LeFever and others, 2011), is assessed with the Three Forks Formation. Where present, the Pronghorn Member is in fluid communication with the underlying Three Forks reservoirs." [Again, note the plurality of "Three Forks reservoirs."]

The file report for the Hess AN-Bohmbach well is confusing (for me). The summary clearly states at the very beginning: "...a horizontal extended-reach lateral meant to test the production potential of the Middle Bakken formations (sic) in the Antelope area."

Then specifically, "the top of the Middle Bakken came in one foot higher than expected at 10,778 TVD.... the curve portion of the well was finished approximately 21 vertical feet into the Middle Bakken Formation at a measured depth of 11,275' and TVD of 10,798."

Then: "North-South Three Forks Lateral  11,275' -- 20,457' MD"

Continuing: "The AN-Bohmbach-153-94-2734H-2 Middle Bakken lateral was started on November 15, 2012, .... total depth .. was called because of a MWD tool failure ... on November 12, 2012, with a MDof 20,458' MD and TVD 10,793 TVD (sic). This was the cessation of drilling....North to South, Three Forks lateral."

The completion data was not there; if it was, I missed it.
