About two years ago, Helis Oil attempted to drill at least two wells to produce simultaneously from the Bakken and Three Forks formations, The Levang (22-150-95) was completed in the TFS and then a second horizontal leg was drilled in the Middle Bakken. The well file indicates they had very high pressures and drilled only a short hole in the Bakken due to "concerns for the crew and rig". I believe this well continues to produce from both the Bakken and TFS.
The same type of completion was attemped at the Helis Linseth well (8-149-95). Again, it appears they had a series problems with this type of dual completion. I think most of the other Helis wells in this area are now being completed in the Three Forks with the Bakken awaiting another round of developement. There are numberous Bakken wells in all directions of from this field (as well as recent Three Forks discoveries). There is very little doubt that the Three Forks/Sanish produce Bakken oil. The main question is if the lower Bakken Shale acts as barrier between the reservoir rock of the Middle Bakken and the Three Forks/Sanish. If this lower shale is a strong barrier it would seem likely you could produce the Three Forks to the extent of its producive life, then plug it off and drill the Bakken leg (or vise-versa) and get full Middle Bakken potential. Wells testing this theory are being planned/ drilled and the results should be known in the not to distant future. It is very likely the results will vary by area within the basin. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Bakken Shale Discussion" group.
