Forty-Eight Wells Per Spacing Unit -- Lynn Helms

Yesterday it was noted that Lynn Helms had said that in the better Bakken, it might take 48 wells per spacing unit. I had not seen the source for that statement.

Another reader was gracious enough to provide the link (see below). This is an incredible briefing provided back in January, 2013. I am amazed that the regional print media did not pick up on this. If any of them did, I missed it. Forty-eight wells/spacing unit in the better Bakken is simply staggering, and when this does not get a headline in the regional media it speaks volumes about local coverage of the Bakken. It really does appear that most folks are focused on that 10-minute wait for a waitress to meet and greet them at a coffee shop.

It's a very, very long presentation, and one can start anywhere to pick up on incredible / staggering data points.

Lynn Helms on the Bakken, EGC, 2013


But start at 22:40 for some interesting data points. At this point, Mr Helms is addressing fracking concerns, and shortly after that he will discuss pilot projects this summer to test 24 wells and 48 wells/spacing unit (disclaimer: there may be typos in the notes below -- listen to the video to confirm; not verbatim throughout; being provided for a couple of reasons):

".... we have essentially infinite capacity for wastewater in the Dakota formation. The only place that we have ever seen the pressure increase in the Dakota (formation) was in Glenburn  and that was after we had put in over 20 million barrels of water into a single well...

.... beneath that ... nine layers of pure salt...

... and then the Bakken ... one cannot fracture the salt formations ... physically impossible to fracture the salt formations...

... earthquakes ... our water disposable is three miles above the earthquake zone... elsewhere they were pushing water into layers at the earthquake zone ... those states (Arkansas and Ohio) learned and have quit those projects ...

.... 640-acre spacing in the Parshall ... 1% of the surface area....have gone from 10% of surface area required for vertical wells to less than one-half of 1% for horizontal wells in the Bakken

.... surface locations on east-west corridor ... using less than one-half of 1% of the landscape....

.... Sanish field...that's the future of North Dakota oil industry ....

... the pattern ...

... the future....

... five productive layers .... middle Bakken and four benches in the Three Forks....

... in "much" of the Bakken, each one of those layers needs to  have 4 to 5 wells placed in it ...

... one operator this summer, first test, two 1280-spacing units and put 24 wells in EACH spacing unit, off one pad, if possible, at most, two pads, with 24 wells on it. The busiest pad right now is a 14-well pad southwest of Williston ... imagine four rows of six wells on one pad ... 8 - 10 acre pad ...

... also the possibility, it may require 48 wells/spacing unit in some of the better Bakken ... this summer another test ... drill out two pads on a 24-well spacing unit (1280) and then go into the middle of another one and drill it out on a 48-well spacing ....

...  you easily get out to 50,000 wells and more than likely well beyond that .... at a minimum,  four to eight wells/spacing unit up to 24 wells/spacing unit, 200 rigs for 21 years....today's rig count ... a constant 190 to 210 rigs for the next 21 years ...

I will quit there; it is a long video with much information.
