Tectonic subsidence analysis of the Williston Basin
The Williston Basin is one of a number of North American intracratonic basins whose subsidence is poorly understood. The Basin is circular in shape and contains nearly 5 km of preserved sedimentary rocks at its center; ranging from Cambrian to Tertiary in age. The Basin's subsidence is investigated …

Thermal history model of the Williston Basin
… the subsurface temperature of a sedimentary basin were investigated by empirical and analytical methods. A review of thermal-mechanical models suggests that the Williston Basin was formed by more than one mechanism. The Williston Basin may have been initiated by a thermal event followed by …

Ordovician corals of the Williston Basin periphery
… indicate that the cratonic platform east of the Williston Basin was e:x:posed for part or all of the time the evaporitic "upper Red River11 was being deposited in the Basin. The paraconformity occupies the same stratigraphic position as the Fort Garry Member, the "upper Red River" and an …

Geothermal regime of the Williston Basin in North Dakota
… the thermal regime of a large intracontinental basin such as the Williston Basin can be enhanced by analysis of the relationships among radiogenic heat production, surface heat flow, formation temperatures, and gravity and magnetic anomaly patterns. Digital processing of the spatial and causal …

Geomechanics and elastic anisotropy of the Bakken Formation, Williston Basin
… yet least characterized sedimentary rocks in the Williston Basin of North Dakota. They are significant sources of hydrocarbon unconventional resources in this basin. This dissertation aims to fulfill an investigation of anisotropy in this rock type in several different facets through exploiting of …

The Newcastle formation in the Williston Basin of North Dakota
… in eastern Wyoming into the subsurface of the Williston Basin. In the Basin, the Newcastle Formation is a very fine to medium grained, gray to white, quartzose sandstone, which overlies the Skull Creek Shale and underlies the Mowry Shale. In area where the Newcastle is absent the overlying and …

Depositional environments and diagenesis, Interlake Formation (Silurian), Williston Basin, North Dakota
… carbonates of large areal extent found in the Williston Basin. The Interlake attains a maximum thickness of about 1,100 feet in western North Dakota and thins to an erosional edge in eastern North Dakota, </p><p> The main purpose of this study was to interpret the depositional and diagenetic …

The Spearfish Formation in the Williston Basin of western North Dakota
… of the Black Hills has been traced into the Williston Basin of western North Dakota. In the basin, the formation can be divided into three members. In ascending order these are: (1) a lower gray shale and red siltstone unit herein named the Belfield Member, (2) a middle salt unit, the Pine …

Reservoir characterization of the Deadwood formation western North Dakota, Williston Basin
… Cambro-Ordovician-aged Deadwood Formation in the Williston Basin was studied by many researchers for oil and gas exploration and alternative energy production. The previous Deadwood Formation published literature documents surface and subsurface research, with the only outcrops exposed in the …

Discontinuities in the Icebox Formation (Ordovician), Williston Basin, North Dakota and Montana
<p>The Ordovician Winnipeg Group is composed of three formations; in ascending order, the Black Island Formation, the Icebox Formation, and the Roughlock Formation. The Icebox Formation is largely composed of shale. This work shows that discontinuities and coarser facies exist within the Icebox …

Conodonts of the Bakken Formation (Devonian and Mississippian), Williston Basin, North Dakota
… elastic unit in the subsurface of the Williston Basin in the United States and Canada. The formation consists of two, mostly non-calcareous, grayish-black to brownish-black shales separated by light to dark gray, calcareous and dolomitic siltstone and fine-grained sandstone. The …

Depositional environments and diagenesis, Winnipegosis Formation (Middle Devonian), Williston Basin, North Dakota
<p>In the Williston Basin, the Winnipegosis Formation is the major carbonate unit of the initial transgressive-regressive pulse of the Kaskaskia sequence. Twenty-two lithofacies were identified by well-log, core, and thin-section studies of Winnipegosis rocks; these belong to seven environments of …

Depositional environments and history of the Winnipeg Group (Ordovician), Williston Basin, North Dakota
<p>The Winnipeg Group (Ordovician) in the Williston Basin, North Dakota, contains three formations. They are, in ascending order, the Black Island Formation, herein informally divided into lower and upper members, the Icebox Formation, and the Roughlock Formation. Strata of the Winnipeg Group …

Sedimentary Depositional Cyclicity, Mission Canyon and Charles Formations (Mississippian), Williston Basin, North Dakota
<p> 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 …

Diagenesis of the middle member of the Bakken Formation, Williston Basin, North Dakota
… concentrated in multiple fields throughout the Williston Basin, there has been no definitive way to determine a well’s potential productivity. This study used core samples, point counting, and petrography to determine the diagenetic traits common to the Middle Member of the Bakken Formation and …
