- 25093, 745, EOG, Wayzetta 150-1509H, Parshall, 52 stages, 14.3 million lbs, t8/13; cum 662K 12/16; just an incredible well, still producing about 6,000 bbls of oil per month, along with 12,000 MCF natural gas / month (2,000 boe). Who wudda guessed that a non-descript middle Bakken well would have produced over 600,000 bbls in just 3.5 years? And as as early as 2013, EOG was using 14 million lbs of sand, and 50+ stages. Truly amazing.
Now an oldie, a "senior well," celebrating its 60th year; fracked 53 years ago:
- 1509, 248, CLR, Kate Hopkins 1, Antelope field, target, the Sanish oil pool; t12/57; cum 594K 12/16; this well was drilled in 1957. Then in 1964, a sundry form reported the operator planned to "fracture this well using 10,000 gallons of gelled water and 3,000 pounds of glass beads." (The original intent was to use 3,000 pounds of glass beads; but the work report said that 10,000 pounds of glass beads were used.)
I've been following this well almost from the beginning of the blog. A few years ago I noted (and blogged) that production was dropping more and more every month, down to less than 20 bbls/month.
Now all of a sudden, a noticeable increase; no sundry form in the file report to suggest why.

This well was shut in from December, 1997, to March, 2000 (over two years).
What did the production profile look like back in June, 1964, when they fracked the well with 10,000 lbs of water and a similar amount of glass beads?

It's hard to say that fracking made that much of a difference. Perhaps flattened out the decline rate.
