Round Prairie -- Very Active -- Bakken, North Dakota, USA

Updates

August 15, 2013:
Round Prairie is about a 20-section oil field west of Williston, right on the Montana state line. It is all prairie. It looks like the field is owned by EOG. The wells are mediocre but they were probably completed before EOG started using newer completion techniques. They should all hit 100,000 bbls in three or four years (some already have); some might take a bit longer. But they should all pay for themselves, and are all good enough to ensure more drilling in this area.  With the exception of one well, they are all producing between 1,000 and 6,000 bbls/month.

I think these are all middle Bakken, and Three Forks might be better in this area.

February 26, 2013: all but two sections are now held by production. All horizontals are long horizontals, except for two short laterals. There are no rigs in the field at this time.

February 26, 2013: Nick H over at Teegue's Bakken Shale Discussion Group has noted that EOG has a great Short Prairie well:

The Round Prairie oil field is very, very active right now: four rigs on site in this small field, about 20 sections. It is "owned" by EOG. The field is directly west of Williston, North Dakota, and abuts the Montana border. In fact, the sections along the border are only about half the size of a "normal" section.

There are currently four rigs on site:
