This phenomenon was brought to my attention by a reader about a year ago, maybe two years ago. Time flies when having fun.
The well:
- 34058, 541, BR, Kermit 8-8-32MBH, Pershing, t8/18; cum 241K 8/20; fracked 7/1/19 7/9/19; 7.1 million gallons of water; 87.7% water by mass;
Look at the rate of produced water in this well (see this post):
BR pumped 169,000 bbls of water down this well for fracking. Look how slowly BR allowed "produced water" to return to the surface. This is simply incredible. After the frack:
- month 1: 7K bbls
- month: 2: 10K
- month 3: 7K
- month 4: 6K
- month 5: 5K
- month 6: --
- month 7: --
- month 8: 3K
- month 9: 9K
- month 10: 2K
- month: 11: 5K
- month 12: 0K
Compared to what I'm seeing by most operators, this is absolutely incredible.
An unintended (positive) consequence: a lot less "craziness" with regard to taking all that produced water away in the first six months; BR "flattens that curve" over two years.
You ever hear of black walnut shells used as a separating media for produced water? I used to work for a firm that sold these separating systems to the SAGD oilfields in Canada and kern river operations in CA.
ReplyDeleteYou know, there's some irony or something there. In fact, I do remember black walnuts, or my mind is playing games with me, but I do vaguely remember that for some reason now that you bring it. But on a multiple choice exam or a matching test I never would have gotten the answer correct. LOL.
