There's a lot of history in the Williston Basin and operators can made educated guesses: the general consensus is that the average EUR for a Bakken well will be 603,000 bbls. Folks also suggest a Bakken well will produce for 25 to 35 years.
Every once in awhile it's fun to stumble upon an old well that almost defies imagination:
- 2079, 33, Amerada/Hess, Newburg-Spearfish-Charles Unit M-711, s1958
- Still producing; on pump
- Pool: Spearfish/Charles
- Cumulative: 809,610 bbls to date. It is currently producing about 75 bbls/month. For most of it's history it produced between 500 and 1,200 bbls / month, although for a short time in the 1980s, they got it up to over 3,000 bbls/month. Unlike the Bakken, it had no steep decline curve
I might come back to this field later.
