Gov. Jack Dalrymple and fellow members of the Industrial Commission will visit places this summer for possible inclusion on a list.
The effort will complement sites already identified for restrictions or conditions by state wildlife, parks and historic preservation officials.
A published report says the idea of compiling the new list came after a public uproar earlier this year when an oil company staked out an area near the site of Theodore Roosevelt's Elkhorn Ranch, part of the national park in the Badlands that bears his name.
Drilling in the Killdeer Mountains also sparked protests from ranchers and American Indians concerned about sacred or historic sites.
