How Much Drilling Is There Yet To Be Done In The Bakken? Two More Decades

From today's operational update from BEXP:

Brigham has two incremental Rough Rider Three Forks wells scheduled to be completed in the near term, both of which are located in McKenzie County, North Dakota. With continued drilling success in the Three Forks in Rough Rider, Brigham estimates that it has the opportunity to add in excess of 500 net drilling locations to its de-risked drilling inventory, which represents an incremental seven years of inventory based on its 2011 drilling pace. When combined with its already significant de-risked drilling inventory, Brigham estimates that it could have 18 years of de-risked drilling locations at its 2011 drilling pace.

That's in agreement with "Basic Analysis of the Bakken," linked at the sidebar on the right: drilling through 2030; production through 2100.
