With regard to this subject (Lodgeple reefs) I welcome any comments from those in the oil industry who can add more information or correct me where I am wrong.
Earlier this morning (or overnight) a reader asked what percent of Lodgepole wells are successful in the area southwest of Dickinson, ND?
This had to do with this well:
33997, dry, Freedom Energy Operating, LLC, Freedom Energy ND 1-15, Heart River, pool: Lodgepole; spud 10/2/17; from the permit, estimated TD = 9,950 TVD;From the geologist's report: this well was targeting a Lodgepole reef:
Oasis Petroleum Freedom ND #1-15 [SE SE Sec. 15, T139N-R97W] is located ~6 miles West of Dickinson, North Dakota. Freedom ND #1-15 is situated within the Heart River Field in Stark County. A vertical hole targeting the porous Reef of the Lodgepole formation.It was a steep learning curve for me when I first learned about Lodgepole reefs. I discuss Lodgepole reefs at this post and that's where I will continue to track them.
I don't know what the percentage is, but anecdotally (based on casual observations or indications rather than rigorous or scientific analysis), these are my thoughts:
- there is a difference between the Lodgepole formation and Lodgepole reefs
- to date, it appears that operators in North Dakota have only been successful hitting the Lodgepole reefs immediately west, southwest, and south of Dickinson, ND and inside city limits
- the farther one gets from Dickinson, ND, the less likely one will hit a reef
- some operators have targeted the Lodgepole formation north of Williston (I forget now how those have turned out)
- once you leave the area west and southwest of Dickinson the likelihood of hitting a Lodgepole reef is pretty unlikely
- even in the area of the Lodgepole reefs it appears to be a real "hit or miss" (no pun intended) outcome
- Lodgepole reef wells are vertical (or directional/vertical) wells and are not fracked; very, very low expense to drill
- I am not quite sure what to think about horizontal wells (if there are any) that target the Lodgepole in the Dickinson area
- Looking at the "Lodgepole wells" west and southwest of Dickinson: I have only looked at a few of these wells; I assume they are all Lodgepole reef wells but my assumption could be wrong
As a "case study," I looked at one Lodgepole well in the Dickinson area, #14213. I have blogged about this well on numerous occasions. From this post: "Denbury Onshore, LCC, may have the most productive well in North Dakota," posted March 27, 2011. This Lodgepole reef well is inside Dickinson city limits.
- 14213, 3,357, Denbury, Dinsdale 2-4, Lodgepole, Stadium, t12/96, cum 4.95 million bbls 9/17; it was shut in all of 10/17; full production profile is at this post.
