Random Note On Documentation (Or Lack Thereof) -- May 18, 2019

Every once in awhile I come across a well that, based on a huge jump in crude oil production and produced water, the well just had to have been re-fracked even though neither the NDIC has a sundry form documenting a re-frack nor FracFocus has any record of a re-frack.

But some of the jumps in production are so great, it's hard to suggest that a re-frack was not responsible. In addition, increased production from neighboring wells near these wells under discussion also suggest there was a neighboring frack.

Just a random comment for what it's worth.

For newbies: when I see production greater than 20,000 bbls in a month, I assume it was recently fracked or very, very near a neighboring well that was just fracked.

For jumps in production from 1,000 bbls/month to 10,000 bbls/month, it's more likely due to "parent-well-uplift" and not due to a re-frack. A re-frack should get a better well than just 10,000 bbls/month (although that does happen, again, depending on the field [location]).
