How About 90,000 Bbls In One Month In A Short Lateral, 320-Acre Spacing, Antelope Oil Field, The Bakken, North Dakota -- December 16, 2015

Note: I track the EOG Riverview wells in the Antelope oil field at this post. It is confusing because there are also EOG Riverview wells in Clarks Creek, just to the west. I track those wells here, as well as the Antelope oil field Riverview wells.

March 7, 2017: a well of interest.

Later, 7:19 p.m. Central Time: see first comment below.

On slide 10 of EOG's 3Qtr presentation, they graphically depict the 4,000+ micro seismic events (fractures) per 1,000' that occur with these high density fracs. This is almost a tenfold increase from frac jobs of just a few years ago. 

What is more significant, however, is that they can contain the frac radius fairly close to the wellbore, thus enabling the placement of far more laterals per DSU.

EOG increased their estimated recovery Bakken wide as a consequence of the Riverview's output. 

Other operators will be sure to follow. 

This is the graphic the reader refers to:

Hold on to your hat. I can't wait to see the frack data on this well; it should be available tomorrow.

Remember: this is a short lateral. The spacing unit: 320 acres according to the permit application.

Spud date: 3/6/15
Cease drilling: 3/20/15

Total depth: 15,564 feet
Total vertical depth: 10,523 feet

Note: almost 90,000 bbls in one month -- rounding up......

We talked about this well several months ago. See this post. Also here. And in a meandering note.

At the links, note the location of this well, and its relationship to Clarks Creek. 

By the way, this is another good example of a well being on the confidential list, then coming off the confidential list and going to SI/NC list, and then going back on confidential list before being fracked. Some years ago, T----- stated that wells don't come on and off and then back on the confidential list.

30286, 1,974, EOG, Riverview 102-32H, Antelope, 23 stages, 12.8 million lbs in a short lateral:

It's going to be interesting to see the frack/completion data tomorrow.

From FracFocus (link here): 

• it was fracked between 5/10/15 and 6/14/15 (inclusive)
• total volume water: 6,437,764 gallons = 53,725,744 pounds of water or about 54 million lbs of water
• by weight, the water + sand: 80.64% was water; 19.23% was sand

Working backwards, I get about 12 million lbs of sand. The most sand I recall used by EOG for a frack was 14 million lbs, although deep in the recesses of my mind, I vaguely recall there might have been a 19-million-lb frack. Ah, yes, it was 19 million lbs; here are some "monster wells" with upwards of 19 million lbs.

By the way look at the halo effect on the earlier well on the same pad. The names of these wells suggest the first well (#19247) is a middle Bakken well, and the newer well (#30286) is a Three Forks well:

• 19247, 1,692, EOG, Riverview 01-32H, Antelope, off-line much of 2015, short lateral, 320-acre spacing; 15 stages, 9.2 million lbs; t11/10; cum 207K 10/15;  

The halo effect may not be much, but there was a slight increase in the production (although, again, it could have been due to other factors than the fracking of neighboring well):
