... Abstract Organic-rich shale characterization in Bakken shales is complex due to the heterogeneity and ambiguity of rock properties, including mineral composition and petrophysical properties such as porosities and fluid saturations. In addition, the dependence of the reservoir properties...

... Abstract Analysis of well interference tests from an extensive data acquisition project in the Bakken shale has shown that wells completed in the Middle Bakken (MB) and Three Forks (TF) can be fully communicated as the result of enhanced fracturing treatments and well spacing designs...

... magnetic logs and pulsed neutron logs help delineate productive zones in the Three Forks Formation. Mineralogy is assessed with logs, XRD, and XRF data. Source rock maturity of the lower Bakken shale also helps define the Three Forks producing fairway. Results/Observations/Conclusions: The Bakken-Three...

... Abstract Researchers from both industry and academia have studied the tight oil resources intensively in the past decade since the successfully development of Bakken Shale and Eagle Ford Shale and made tremendous progress. It has been recognized that locating the sweet spots in the regionally...

... permeation in Bakken rock samples. Static extraction tests were performed on rock samples representative of the Bakken reservoir (siltstone) and source rocks (Upper and Lower Bakken shales). A dynamic CO 2 injectivity test was also performed on an unfractured Bakken shale sample that was confined...

... for understanding rock behavior in the field. The pore size distribution and connectivity, mineralogy, total organic carbon of cores from the Bakken shale play were investigated from two locations and depths. Multimodal characterization techniques including carbon analysis (TOC), X-ray diffraction (XRD), computed...

... (e.g., 5000 psi and 230°F). Results from 20 samples showed that supercritical CO2 enables extraction of a considerable portion (15%– 65%) of the hydrocarbons from the Bakken shales within 24 hours. The results may be used to improve modeling and forecasting the effects of CO2 enhanced oil recovery (EOR...

... Abstract The marine oil-prone lower and upper Bakken shales are world class source rocks in the Williston Basin, which are a significant element for the Bakken Petroleum System (BPS) and sourcing reservoirs in the middle Bakken, upper Three Forks, and lower Lodgepole formations. A good...

The Upper Bakken Shale in North Dakota is the focus area of this study. 112 wells from five of the main producing counties in North Dakota; namely Burke, Mountrail, McKenzie, Dunn, and Williams, are analyzed. Shear wave velocity is first...

... to develop fracture networks. We investigate the mineralogy-based and elastic property-based brittleness index of the Bakken Formation. The results exhibit excellent correlation between two methods. It also indicates that the black organic-rich Upper and Lower Bakken Shale typically appears to be more...

... Abstract 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). 10 to 400 billion barrels of oil have...

The principal source bed for the Three Forks is the Lower Bakken Shale (LBS). Source rock maturity is a primary control on the extent of Three Forks production across the basin. Poor...

... Bench of the Three Forks reservoir may contribute to some minor extent but typically exhibits properties characteristic of much lower reservoir quality. Geochemical data collected from cuttings in the Lower Bakken Shale, directly above the upper bench of the Three Forks suggest that the shale...

This paper focuses on examining the efficacy of fracturing stages in Bakken Shale formations based on the field production data. We observe that as the number of stages increases, the efficacy of incremental stages decreases...

... Abstract The impact of petroleum-expulsion fractures on productivity of the Bakken shales were investigated by integrating epifluorescence petrography, pressure transient analysis and analysis of petroleum-expulsion fracturing. In early exploration vertical wells, drilling breaks from ten...

... The Upper and Lower Bakken shales are the source beds for the Bakken Petroleum System of the Williston Basin. Reservoirs for this system include the shales, the lower Lodgepole, Middle Bakken silty dolostones, Pronghorn dolostones, and Three Forks silty dolostones. The Upper Shale was a drilling...

In order to better identify and characterize these relationships a series of "Hydrocarbon Yield" maps were created for the Upper and Lower Bakken shales using a method recently described by Ruble and Lewan (2013). The method computes a volume...
