Updates
July 27, 2015: the CLR Salers Federal wells are a major topic of discussion by Micheal Filloon, this date, particularly with regard to the halo / communication effect of fracking neighboring wells.
Original Post
There is so much in the Bakken I simply cannot keep up. Hopefully, the slump in oil prices will slow things down.
Just how good are the wells and just how fast are completion strategies changing? Over at the sidebar at the right, I have a link to
oil fields in the North Dakota Bakken.
A couple days I started
updating the Antelope oil field in the reservation (NOT the Antelope Creek oil field west of Watford City). I updated a lot of the field, but there is much more left to do. In the process I came across a Continental Resources well with an example of their new completion strategy:
- 28330, 1,716, CLR, Salers Federal 3-27H, six days to vertical depth; six days to drill the lateral, target zone 11 feet to 23 feet below the top of the middle Bakken (so I assume the middle Bakken thickness in this area ranges from 20 to 40 feet), background gas was averaged about 650, though there were spikes to 2750; 50 stages; 19 million lbs; 14 days spud to TD, t10/14; cum 41K 10/14;
I don't recall the largest amount of sand EOG has used on a well, but
19 million lbs of sand/ceramic has to be a record for sand/ceramic mix. EOG uses only sand as far as I know. Almost all off the proppant used by CLR in #28330 was sand, however, I believe less than 2 million lbs ceramic;

Regular readers might be surprised at what CLR is doing.
*********************************
Here's an EOG well in the same field:
- 24337, 2,519, EOG, Hawkeye 3-2413H, 28 stages; 10 million lbs sand, t5/13; cum 452K 10/14;
- EOG says it will be utilizing "up to 4 NGL stripping skids on this pad in an effort to reduce VOC volumes. Spud date, December 16, 2012; TD, January 11, 2013. Thickness of middle Bakken appears to be about 50 feet at this location.
Yes, that's almost a half-million bbls in less than 18 months (including one month with NO production; and with three months on-line for only about 50% of the time). And, yes, it's tracked on the "
Monster Well" page.
