Hydrogeological And Hydrogeochemical Evaluation Of A Proposed Flue Gas Cleanup Dry Waste Disposal Pit Near Beulah, North Dakota, Nathan T. Hunke Jan 1989

Hydrogeological And Hydrogeochemical Evaluation Of A Proposed Flue Gas Cleanup Dry Waste Disposal Pit Near Beulah, North Dakota, Nathan T. Hunke

Theses and Dissertations

The Coyote I electrical operating station of the Montana Dakota Utilities Company (MDU) is located near Beulah, North Dakota. Flue gas cleanup {FGC) dry waste is generated by the facility in the conversion of coal to electricity. MDU submitted a permit application to the North Dakota State Department of Health {NDSDH) to dispose of FGC dry waste in a strip-mined area 1.6 kilometres northeast of the plant.

Two disposal pits were proposed by MDU, a Phase I and Phase II pit. The objectives of the investigation were to determine the hydrogeological and hydrogeochemical suitability of the site for FGC waste …


Sedimentary Depositional Cyclicity, Mission Canyon And Charles Formations (Mississippian), Williston Basin, North Dakota, Jean L. Hoff Jan 1989

Sedimentary Depositional Cyclicity, Mission Canyon And Charles Formations (Mississippian), Williston Basin, North Dakota, Jean L. Hoff

Theses and Dissertations

Workers within the Williston Basin have repeatedly reported the presence of sedimentary cyclicity within the carbonate and evaporite succession of the Mississippian Madison Group. Descriptions of cyclicity are diverse and commonly conflict. Previous work has been exclusively qualitative. This study used a group of statistical techniques in a method designed specifically for the objective identification and evaluation of cyclicity in the lithofacies sequence of the Mission Canyon and lower Charles Formations in North Dakota.

Twelve cores were sampled at every visually distinguishable lithologic unit. Forty-six lithologic components were counted in each sample on a presence-absence basis. The phi association coefficient …


The Hydrogeology Of A Landfill Located In Fine-Grained Lacustrine Sediments In A Saline Discharge Area West Of Grand Forks, North Dakota, John T. B. Betcher Jan 1989

The Hydrogeology Of A Landfill Located In Fine-Grained Lacustrine Sediments In A Saline Discharge Area West Of Grand Forks, North Dakota, John T. B. Betcher

Theses and Dissertations

The Grand Forks Municipal Landfill, located in the Red River Valley of eastern North Dakota, accepts household refuse from the city of Grand Forks and from surrounding rural communities including several towns in northwestern Minnesota. The landfill occupies 160 acres (64.8 hectars) and another 160 acres (64.8 hectars) is available for expansion. The trench method of disposal is used at the landfill.

A geologic and hydrogeologic investigation was undertaken at the landfill to determine the characteristics of the shallow, saturated, fine-grained lacustrine sediments for solid waste disposal. Test holes were drilled to collect core samples for textural analysis, clay mineralogy …


Depositional Environments And Diagenesis Of The Lower Duperow Formation (Devonian), Billings Anticline, North Dakota, Randolph B. Burke Jan 1989

Depositional Environments And Diagenesis Of The Lower Duperow Formation (Devonian), Billings Anticline, North Dakota, Randolph B. Burke

Theses and Dissertations

The Duperow Formation is an Upper Devonian (Frasnian) subsurface unit in the Williston Basin in the north-central United States and south-central Canada. Despite its economic importance for hydrocarbons, no detailed accounts have been published on the Duperow Formation that integrate depositional environments, lithology, diagenesis, and pore studies on either a regional or local scale. It was the purpose of this study to construct a model of the depositional environments and diagenesis of the lower Duperow Formation in the Billings Anticline of west-central North Dakota, based on detailed analysis of 17 cores (225 m, 739 ft) and associated wireline logs and …


Foraminiferida Of The Madison Group (Mississippian) Of The Williston Basin, North Dakota, Kurt E. Eylands Jan 1989

Foraminiferida Of The Madison Group (Mississippian) Of The Williston Basin, North Dakota, Kurt E. Eylands

Theses and Dissertations

More than 1500 thin-sections from 73 wells in the North Dakota part of the Williston Basin were searched for their foraminiferal content. This thin-section survey of the Bottineau, Tilston, Frobisher-Alida, and Ratcliffe intervals yielded more than 700 identifiable foraminifers assigned to 26 species.

Most of the Madison foraminifers of the Williston Basin can be placed in one of two superfamilies, the Tournayellac1a and the Endothyracea. The Bottineau and T11ston intervals yielded more specimens from the superfamily Tournayellacea while the Frobisher-Alida and Ratcliffe intervals yielded more specimens from the superfamily Endothyracea.

The foraminifers occurred in irregular stratigraphic zones The Bottineau and …
