Abstract

Discovery of highly productive wells at shallow depths, with good oil and gas reserves, was the bright spot of Montana oil history in 1963, and there were successful tests as deep as Ordovician Red River formations. Of 8 discoveries listed for North Dakota, one in the Madison formation in Renville County, far removed from present producing areas, shows promise of extensive development. There were no new discoveries in South Dakota, although the older Barker Dome field showed signs of renewed activity.
