The Upper Red River Formation (Ordovician) In Western North Dakota, Harlan K. Friestad

Theses and Dissertations

The upper Red River Formation in Western North Dakota consists of cyclic sedimentary rocks having four main porosity zones which contain most of the oil and gas found in the formation. It was divided into three distinct units that were traced throughout western North Dakota on mechanical logs. In ascending order these are the P, R, and F intervals which consist of alternating sequences of dolomites, limestones, and anhydrites. Facies changes, occur within the P interval both on a regional and a local scale, typically from dense limestones to porous dolomites.

Lower Paleozoic Chitinozoans And Scolecodents From North Dakota, Douglass H. Morgan

Theses and Dissertations

Chips from cores of the Red River and Stony Mountain Formations of Ordovician age and the Dawson Bay Formation of Devonian age in North Dakota were taken at three-foot intervals, dissolved in acid, and the residue examined for insoluble, pseudochitinous microfossils. Chitinozoa, an extinct order of rhizopod protozoans, were found in abundance along with lesser numbers of scolecodonts, the mouth parts of polychaete worms. Because the study was restricted to the core available at the North Dakota Geological Survey, which rarely included complete sections of the formations, a complete picture of the distribution of these forms must await the more …

The Micropaleontology And Stratigraphy Of The Subsurface "Heath" Formation (Mississippian-Pennsylvanian) Of Western North Dakota, Harold C. Ziebarth

Theses and Dissertations

The thesis here abstracted was written under the direction of F. D. Holland, Jr., and approved by Wilson M. Laird and Walter L. Moore as members of the examining committee, of which Dr. Holland was chairman.

The “Heath” Formation, between the underlying Otter and the overlying Amsden(?) Formations in the subsurface of southwestern North Dakota, is a source of petroleum in the Scoria-Fryburg, Rocky Ridge and Dickinson oil fields. Cores, cut from the interval under study, of twenty wells in this area, were the source of fossil and lithologic samples studied. Changes in lithology in these cores compared with changes …
