This book was released on 2016 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Upper Devonian-Lower Mississippian Bakken Formation in the Williston Basin is an important source rock for oil production in North America. The Bakken Formation is comprised of three units: Upper and Lower Bakken black shales and Middle Bakken Member. Upper and Lower Bakken shales are high quality source rocks which source reservoirs in the Middle Bakken, Upper Three Forks and lower Lodgepole Formations. The Middle Bakken Member, consisting of predominantly gray, silty and sandy dolostone, is under investigation in this study. The goals of this study are to determine the regional distribution of lithofacies and depositional environments of the Middle Bakken Member and explain diagenetic sequence and reservoir quality parameters in the Williston Basin. The reservoir quality of the Middle Bakken Member is mainly influenced by mineralogical composition and cementation resulting in low porosity and permeability and linked to lithofacies distribution in the basin. Dolomitization is pervasive throughout the unit, and also occurs as dolomite cement. Moreover, cementation occurred including quartz overgrowths, K-felspar, clay cement and pyrite as both cement and nodules. Not only dolomitization but also pyrite cementation plays an important role in reducing pore space in the reservoir. The pore types that were identified are intergranular, intragranular, fracture and moldic pores. Secondary intragranular porosity generally resulted from dissolution of biogenic fragments and dissolution of other unstable minerals including feldspar and dolomite. In this study, five lithofacies and one sandy interval within lithofacies C were described throughout the North Dakota portion of the Williston basin. The sandy interval in Lithofacies C was interpreted as bars or channel fills, which differentiates this study from previous studies in terms of core description. N-S, W-E, NE-SW, NW-SE oriented cross-sections drawn via cores suggest that the lithofacies of the Middle Bakken Member pinch out towards the edges. However, the anticlines in the basin affect their thickness distributions. Sandy interval in Lithofacies C reaches its thickest succession in the center of the basin. Lithofacies C and D consist of up to 80% of dolomite although the other lithofacies consist of relatively lower dolomite (up to 65%). While well logs indicate 4-8% of porosity, point-counting results show up to 5% of porosity. The sequence of diagenetic events in the North Dakota portion of the Williston Basin is from youngest to oldest: micritization, mechanical and chemical compaction, calcite cementation, dolomitization, pyrite cementation, microcrystalline quartz cementation, syntaxial calcite overgrowth, quartz overgrowth, K-Feldspar overgrowth, dolomite dissolution, feldspar dissolution, dedolomitization, fracturing, anhydrite cementation and hydrocarbon migration.

This book was released on 2014 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, the Pennsylvanian Tyler Formation has been targeted as a conventional reservoir consisting of barrier island and channel sand deposits in the southwestern Williston basin, North Dakota. The purpose of this study is to investigate the cyclothemic stacking patterns in the Tyler Formation near the depocenter of the basin to improve the petroleum system model. Utilizing one core located in central McKenzie County, the litho-stratigraphy of the cyclothems is characterized. Six facies were identified and described in each cyclothem. A network of six structural and stratigraphic cross sections was constructed. Structural cross sections and structural maps illustrate that the Tyler Formation dips to the northeast. The stratigraphic cross sections illustrate that the Tyler cyclothems were deposited during a period of sea level transgression and high stand. These cross sections and isopach maps also depict a discontinuous sand facies which does not occur in the core studied. New permeability and porosity data of two carbonate intervals as well as publically available data from several other intervals in the core were used to characterize the reservoir model of these cyclothems. The majority of the identified facies had less than one nanodarcy of permeability, strongly indicating this was a very tight formation. It is concluded that the overall tight-rock characteristics of the carbonate and siliciclastic rocks within the lower Tyler Formation may indicate an unconventional petroleum play. The sand facies within the upper Tyler Formation might lead to a conventional approach if hydrocarbons are present.
