December 1, 2017: from comments below, from a reader --
The operators are routinely tight lipped about the details of completion practices, but info from third parties can often be pieced together to get a sense of what is going on.
The recent introduction of Microproppants seems to be opening up vastly more area of the rock - Stimulated Reservoir Volume (SRV) is the often used term - that is able to be propped.
Some engineers claim the increase in area can be tenfold from earlier fracturing.
In addition, both the near wellbore and far field diversion products have enabled WAY more complete rubbilization of the rock and to effectively control its spread both vertically and laterally.
Based on two recently fracked DUCs, it appears that CLR is keeping number of stages in a moderate range (about 40) but significantly increasing the amount of proppant, using more of the latter in the middle Bakken compared to what is used in the Three Forks:
- 28998, 1,880, CLR, Radermecher 4-22H2, Camel Butte, 39 stages; 11 million lbs, t2/17; cum 244K 10/17;
- 28991, 2,120, CLR, Radermecher 2-22H1, Camel Butte, 39 stages; 17 million lbs, t2/17; cum 270K 10/17;
