Random Update / Example Of A BR Well In The Core Bakken -- December 16, 2018

This page won't be updated. The Anderson Ranch wells are tracked here.

In the early early days of the boom, in the core Bakken, we might have seen nice 24-hour IPs, but the wells declined quickly. The production after the initial frack might peak at about 8,000 bbls/month; quickly decline; and be lucky to hit 100,000 bbls in two or three years.

Disclaimer: I am inappropriately exuberant about the Bakken.

Now we are seeing more and more wells in the core Bakken, looking like this:
  • 32635, 476, BR, Anderson Ranch 3A-MBH, API: 33-053-07585, gas shows were very, very low, averaging 105 units but did register a hight of 8,934 units, Camel Butte, huge well, 23 stages; 9.9 million lbs sand, t5/17; cum 348K 10/18;
Note the initial production. Instead of 8,000 bbls at the peak following the initial frack we are seeing the peak at over 30,000 bbls. Instead of seeing the decline in just a few months, this well was still producing over 30,000 bbls/month  six months later. And then most importantly, in less than 18 months, cumulative at 350,000 bbls.

When the boom began, many thought that the EUR for Bakken wells would be 350,000 bbls.

This well has produced that much in 18 months, and it will go on producing for 35 years. Over its lifetime, it will undergo multiple workovers; mini-re-fracks; major re-fracks; effect of neighboring wells; better re-completion strategies; etc.

This well was off-line in July, 2018, for a workover.

And, oh, by the way, for those folks who might argue that huge amounts of expensive proppant (ceramic, for example) is being used, this used a fairly moderate/large amount of proppant but it was all white sand and mesh; no expensive ceramic. In addition, only 23 stages. Imagine the production ad the typical 50 to 60 stages been employed.
