Llithostratigraphic Investigation And Components Of A Complete Petroleum System Within An Upper Devonian Carbonate-Evaporite Sequence : The Birdbear Formation, Williston Basin, North Dakota, Benjamin L. Engleman
Llithostratigraphic Investigation And Components Of A Complete Petroleum System Within An Upper Devonian Carbonate-Evaporite Sequence : The Birdbear Formation, Williston Basin, North Dakota, Benjamin L. Engleman
Theses and Dissertations
The Birdbear Formation of the Williston Basin of southwestern North Dakota represents one carbonate-evaporite sequence of the Late Devonian. The formation was deposited during regression on a broad, shallow epeiric shelf and is composed principally of dolomite, limestone and anhydrite. The Birdbear Formation is conformable with the Duperow Formation below and the Three Forks Formation above. The designations of 17 lithofacies form the context for describing hydrocarbon generation, migration and accumulation. Rock-Eval 6 and total organic carbon of 42 samples were used to identify the quality of source rocks present in the formation. Good and excellent source rocks were identified …
Reservoir Analysis Of The Birdbear Formation (Devonian) In Northwestern North Dakota, Mitchell V. Sigler
Reservoir Analysis Of The Birdbear Formation (Devonian) In Northwestern North Dakota, Mitchell V. Sigler
Theses and Dissertations
The Birdbear Formation of northwestern North Dakota is a carbonate-evaporite unit deposited on a rimmed carbonate platform during the Late Devonian. The upper and lower contacts are conformable and the formation has been previously divided into two informal upper and lower members. Analyses of core intervals, thin sections, total organic carbon, and wire line logs have allowed for the identification of three informal units that are divided based on lithologic changes, depositional settings, and reservoir characteristics of the formation. Each unit is identified and mapped across the study area using core to log correlations. The units are recognized and named …
Interplay Of Porous Media And Fracture Stimulation In Sedimentary Enhanced Geothermal Systems : Red River Formation, Williston Basin, North Dakota, Caitlyn M. Hartig
Interplay Of Porous Media And Fracture Stimulation In Sedimentary Enhanced Geothermal Systems : Red River Formation, Williston Basin, North Dakota, Caitlyn M. Hartig
Theses and Dissertations
Fracture stimulated enhanced geothermal systems (EGS) can be installed in both crystalline rocks and sedimentary basins. The Red River Formation (Ordovician), which lies between 3.6 and 4.2 km depth in the Williston Basin, is a viable site for installation of sedimentary EGS (SEGS). SEGS is possible there because temperatures in the formation surpass 140° Celsius and the permeability is 0.1-38 mD; fracture stimulation can be utilized to improve performance. The main objectives of this project were 1) to determine the spatial variation of the intrinsic properties of the Red River Formation across the study area, and 2) to understand the …
Geothermal Regime Of The Williston Basin In North Dakota, Faye N. Ricker
Geothermal Regime Of The Williston Basin In North Dakota, Faye N. Ricker
Theses and Dissertations
Understanding 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 relationships gives insight into the effect of basement heat production on the thermal state of the basement rocks and the overlying sedimentary successions. These relationships provide valuable insight on the radioactive heat contribution to heat flow, heat flow from the lower crust, composition of the upper crust, and the potential for geothermal power generation. The specific …
