Ten (10) Wells In One 1280-Acre Spacing Unit -- The Bakken, North Dakota, USA

Slide 11 of CLR's most recent corporate presentation shows rationale for ten (10) wells in each 1280-acre spacing unit in core Bakken. Actually, one can make a case for twelve (12) or more wells in the best such spacing units.

Slide 21 suggests a cost of about $30/bbl, excluding the production tax.
