Quote.... Three Forks lower benches
DD on Continental and Halcon lower bench wells Three Forks benches 2and 3 were separated by 880 feet at depth and alternated.
The companies also had an either or situation regarding Three Forks in that they chose a bench 1, 2, or 3 but not drilling each under one another. If bench 3 was chosen they did that first and let that settle for 3 ½ to 4 months. Continental had 11 Rollefstad wells and they were about 90% of a Bakken and are over 100K BOE in 5 months (after the settle period).
SSN Bootleg 8 messed up the other wells above and they had to be cleaned out. TB skidded over Ironbank 8 well.
Now that was the bad news.
Ironbank 6 and 7 should be complete and that along with the 35 stage Bakken Billabong as in process or being FRAC’D.
Wait I ran out of fingers and toes to count these wells; might need my slide rule.
