Random Update Of An Old EOG Short Lateral In Parshall Oil Field -- March 30, 2018

For newbies: Some folks keep talking about newer wells in the Bakken affecting older wells in a negative manner. That's possible. I don't know. I just see a lot of these examples, where there is a jump in production in an older well when neighboring wells are fracked.

In the production profile below, between early 2015 and early 2013, just two years:
  • a jump in production from 2,000 bbls/month to 7,000 bbls/month, November, 2013
  • a jump in production from 5,000 bbls/month to 8,000 bbls/month in October, 2014
Not only is there a jump in production for a month or two, but the affect lasts several months, extending the period in which there is higher production, affecting a) the decline rate; and, b) the EUR.

Note: prior to neighboring wells being fracked, this well (#16543) was down to 2,000 bbls/month, arguably a very mediocre well. That was back in March, 2013. After neighboring wells were completed, not only was there a significant jump in production on two occasions, but the baseline production was up to 4,000 bbls/month.

A Bakken trope/meme (I don't know if it's a myth): new wells will result in less production from older wells. Example after example proves this is not the case.

The well, a single section EOG well in Parshall oil field:
  • 16543, 1,015, EOG, Florence 1-04H, Parshall, t7/07; cum 511K 1/18;

The neighboring wells and the test dates of those wells:
  • 25254, EOG, t11/13;
  • 27042, EOG, t8/14
Remember, the index well is a short lateral. Had this been a long lateral, one can argue that total production would have been double what we see here.
