An Examination of the Mineralogy and Lithology of the Bakken Shale with Implications upon the Bakken Petroleum System, Southeastern Saskatchewan
Late Devonian and Early Mississippian Bakken shales are important source rocks to the oil accumulations in southeastern Saskatchewan. However, to date there is lack of knowledge concerning the mineralogy and lithology of the Bakken shales, which may impact the source effectiveness and heterogeneity …

Geomechanics and elastic anisotropy of the Bakken Formation, Williston Basin
<p>Many of the earth’s rocks exhibit anisotropic characteristics. Anisotropy is particularly common in many sedimentary rocks, such as shales. Anisotropy is defined as the spatial alignment of mineral grains, layers, fractures and stresses which causes elastic wave velocity and other elastic …

Conodonts of the Bakken Formation (Devonian and Mississippian), Williston Basin, North Dakota
<p>The Bakken Formation is a thin (maximum 145 ft., 44 m), predominantly 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 …

Hydraulic fracturing design for horizontal wells in the Bakken formation, Williston Basin
… and performance of hydraulic fracturing in the Bakken Formation, Williston Basin, are examined. </p><p> To accomplish the above objectives, this dissertation is divided into four major sections that include: 1) basic principles of geology, lithology, and reservoir aspects of the Bakken …

Diagenesis of the middle member of the Bakken Formation, Williston Basin, North Dakota
<p> The shales of the Bakken Formation have been extensively studied since the discovery of oil, but little attention has been paid to the middle reservoir member. Successfully produced wells are concentrated in multiple fields throughout the Williston Basin, there has been no definitive way to …

DESCRIPTION OF THE BAKKEN FORMATION’S ROCK PROPERTIES OF THE WILLISTON BASIN, NORTH DAKOTA
… observed in the unconventional reservoir. The Bakken Formation is one of the main hydrocarbon-prone formations in the Williston Basin. This formation has generated approximately 200 to 400 billion barrels of oil and boasts a low permeability system. Three distinct members (the Upper Shale …

Macrofossils and biostratigraphy of the Bakken Formation (Devonian and Mississippian) in western North Dakota
<p>The Bakken Formation, up to 145 feet thick in North Dakota, is a subsurface formation in the Williston Basin that typically consists of two black shale members separated by a middle member of predominantly gray siltstone or silty limestone up to 85 feet thick.</p> <p>Well over 500 macrofossils …

Geological Effects and Petrophysical Flow Unit Model for the Middle Bakken Member, South-East Saskatchewan
The Devonian-Mississippian Bakken formation is a relatively thin heterogeneous unit that stretches across the subsurface of the Williston Basin in North Dakota, Montana, Saskatchewan, and Manitoba. In terms of oil and gas exploration, the unit is undoubtedly one of the most important and ranks high …

Analysis of petroleum source rocks of the Bakken Formation (Devonian and Mississippian) in North Dakota
<p>The Bakken Formation of North Dakota consists of upper and lower, black, organic-rich shales separated by a calcareous siltstone middle member. The formation is a relatively thin unit (maximum thickness of 145 feet) with the lower shale .attaining a maximum thickness of 50 feet and the upper …

Fracture-enhanced porosity and permeability trends in the Bakken Formation, Williston Basin, western North Dakota
… play a critical role in oil production from the Bakken Formation (Devonian and Mississippian) in the North Dakota portion of the Williston Basin. The Bakken Formation in the study area is known for its low matrix porosity and permeability, high organic content, thermal maturity, and relative …

Source rock potential of the Bakken shales in the Williston Basin, North Dakota and Montana
The lower and upper Bakken shales are world class source rocks in the Williston Basin, sourcing reservoirs in the Bakken, upper Three Forks, and lower Lodgepole formations, which comprise the economically significant Bakken Petroleum System (BPS). Lower and upper Bakken shales exhibit a wide range …

Sedimentology, ichnology, and stratigraphic architecture of the upper Devonian-lower Mississippian Bakken Formation, west-central Saskatchewan
The Upper Devonian-Lower Mississippian Bakken Formation has recently become a prolific producer of light gravity oil in southeastern Saskatchewan since the advent of horizontal drilling and multi-stage hydraulic fracture technologies, which has resulted in an increase in geological studies within …

Conodont biostratigraphy of the Bakken and lower Lodgepole Formations (Devonian and Mississippian), Williston Basin, North Dakota
… obtained were used in the biozonation of the Bakken and basal Lodgepole Formations in the Williston Basin in North Dakota. The Bakken Formation of Devonian and Mississippian age and the Lodgepole Formation, entirely of Mississippian age, are subsurface units in North Dakota. The Bakken …

Sequence Stratigraphy, Depositional Environments, and Regional Mapping of the Late Devonian Interval, Upper Three Forks Formation, Sanish Member, and Lower Bakken Shale, U.S. Portion of the Williston Basin
… Devonian upper Three Forks, Sanish, and lower Bakken units from eight wells were examined and described at the North Dakota core depository. Core descriptions, wireline log correlation and mapping, and X-ray diffraction (XRD) data were integrated to recognize seven facies: The Three Forks D and …

Seismic Characterization of Faults from 3-D Seismic Data: Fault Detection, and Characterization of the Bakken Formation
… characterize faults from 3D seismic data in the Bakken Formation. I use principal component analysis (PCA) for automatic fault detection. The PCA fault attribute indicates significantly different, and geologically more plausible, 3D fault distributions than do conventional seismic attributes, …

Imaging a Hydraulically Fractured Bakken Shale Reservoir Using 4D-Tomography and Reverse VSP Techniques with Perforation Shot Sources
… it was applied to real data acquired in the Bakken Formation of the Williston Basin (North Dakota). Using eighty shots triggered in two producer wells and recorded by six vertical wells, I calculated the P-wave fastest azimuth yielding approximately N70oE using a reverse VSP walkaround …

Effect of thermal maturity on nanomechanical properties and porosity in organic rich shales (a Bakken shale case study)
… Textural and nano-mechanical properties of Bakken Shae samples from a wide range of thermal maturity were studied at natural state and after hydrous pyrolysis using FESEM imaging, nanoindentation and nano-DMA techniques. Laminated texture of shales at low maturity levels (caused by abundance …
