May 16, 2012: a reader noticed that Nomac 312 is no longer on the active drilling list which suggests that CHK has completed drilling the two wells on the Grenz pad. See below. Remember: McLendon said he was going to test a new formation (other than the Bakken / Three Forks); maybe this is what he was referring to.
Original Post
According to the NDIC active rig list, Chesapeake is moving rig NOMAC 312 from Hutzenbiler 9-137-99 A 1H to Grenz 26-138-98 A 2H about 9 miles to the northeast.
According to the well file, the Three Forks is the target of the Hutzenbiler.
Note: Chesapeake has two wells on one pad in this area, each apparently targeting a different formation:
- 22153, loc, Grenz 26-138-08 A 2H, Mission Canyon Pool; wildcat;
- 22185, conf, Grenz 26-138-98 A 1H (already drilled), wildcat, Bakken/Three Forks Pool
*********************
The Madison group is composed of the Charles, Mission Canyon, and Lodgepole formations.
Prior to the current Bakken Boom, 60% of all oil produced in North Dakota had come from the Charles and the Mission Canyon.
Note: many wells I have mentioned in earlier posts are "Madison" wells -- without additional information, one would not know if Charles, Mission Canyon, or Lodgepole. I don't recall seeing any "Mission Canyon" wells in the past; I have always seen Madison wells (of the three in this discussion).
The Lodgepole and Mission Canyon are carbonates and have porosity; the Charles Formation is dominated by [salts] and lacks permeability.
They previously drilled on that section in January. Will they be re-entering the same hole?
ReplyDeleteNo, Chesapeake will have two wells on one pad in that section:
Delete22153, loc, Grenz 26-138-08 A 2H, Mission Canyon Pool; wildcat;
22185, conf, Grenz 26-138-98 A 1H (already drilled), wildcat, Bakken/Three Forks Pool, this must be the one that was previously drilled that you are referring to.
Notice the different pools; and note that 22153 is "loc" which means that they have not started drilling.
So, no, they are not re-entering the same hole. Second hole on same pad.
Mission Canyon is "above" the Bakken.
Has there been any activity near the Regent area? My family owns mineral rights southwest of there. There are dry wildcat holes from the 1960's and 70's that dot the area but of course they were using "old technology" then. Thanks
ReplyDeleteUnfortunately not. Nothing in the immediate area. There is one rig about 35 miles northwest of Regent, but that's about it.
DeleteI know the people who have minerals under the Grenz wells. They were told the rig (Nomac 312) was moving north for about 6 months and would be back for Chesapeake after the 6 months.
ReplyDeleteThe timing (6 months) makes sense.
