The Depositional Environment Of The Kisbey Sandstone From The Madison Group (Mississippian), North-Central North Dakota, Gregory D. Waltz

Theses and Dissertations

The Kisbey Sandstone, also known as the K-2 marker, was studied to understand its depositional environment. It occurs within the Madison Group (Mississippian) of North Dakota. The Madison Group is a regressive, near-shore sequence. In descending order, this Group comprises the Charles, Mission Canyon, and Lodgepole Formations. The K-2 marker appears as well-log defined unit between the Charles and Mission Canyon Formations. Seven counties comprise the 7100 square mile study area. They include Rolette, Bottineau, Renville, McHenry, Ward, Burke, Mountrail Counties, and the southern most adjacent townships in Canada.

For this study, 1677 well-logs were examined. These data were analyzed …

A Mechanical Well Log Study Of The Popular Interval Of The Mississippian Madison Formation In North Dakota, C. W. Cook

Theses and Dissertations

The Poplar interval of interbedded evaporites and carbonates forms the uppermost part of the Mississippian Madison Forr.1ation in western North Dakota. A detailed mechanical well log study of the Poplar interval in North Dakota was conducted to interpret the Poplar's regional geology and to attempt to locate areas with potential for petroleum production. Limestone, dolomite, anhydrite and salt were differentiated using mechanical well logs.

The complex facies of the Madison are subdivided into para-time rock units (the Poplar interval is one) on the basis of extensive thin anhydrite beds which are considered time-parallel.

The base of the Poplar interval is …
