This is a great example of how operators "extend" the lives of their Bakken wells. See production profile at this link.
The well:
- 16646, 257, CLR, Ryden 21-24H, Jim Creek, t7/07; cum 246K 8/18
- this well was never all that great during its first year of life
- this was was never re-fracked; it was drilled, stimulated, and the operator moved on
- the well may have had any number of work-over rigs over the years; that I do not know
- after the initial stimulation, the well produced a maximum of 7,176 bbls (1st month) and 6,736 bbls (4th month); after that it declined and plateaued at about 2,000 bbls/month; becoming a "steady Eddy"; nothing remarkable
- first production 8/07
- peaked 11/07 (4 months later)
- plateaued by 4/08 to about 2,000 bbls/month
- second plateau by 5/10 to about 1,500 bbls/month
- continued to decline slowly and then, all of a sudden, 3/15, jumped to 2,600 bbls/month (from 1,000 bbls/month previously) -- probably a work-over rig or neighboring well activity
- off-line for a couple of months, no doubt due to neighboring well activity
- 11/15: jump to 5,600 bbls/month
- some volatility between then and now but still at 3,400 bbls/month -- much better and lasting much longer than the production after it was initially drilled back in 2007
- this well will most likely be re-fracked two or three more times in it's 35+ year life
