Abstract:

Exploration drilling increased sharply in 1968. The success in Wyoming continued to be high, but in Montana and North Dakota was rather low because many unsuccessful wells were drilled in areas of sparse control as part of multiwell stratigraphic test programs.

Twenty-six discoveries in the Muddy Sandstone in the Powder River basin of Wyoming highlighted the year. Interest was spurred in the deeper part of the Williston basin by discoveries in the Red River Formation in eastern Montana. Considerable leasing and drilling activity was in progress along the boundary between Montana and North Dakota at year end.

Although large lease blocks were taken in South Dakota in 1967 and 1968, drilling activity is still at a low level. The need to evaluate these holdings should produce considerable drilling in 1969.

There was no drilling in Idaho in 1968.
