Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Utica Shale is an Ordovician age rock unit found throughout most of Ohio and much of the Northeastern United States. Recently, the Utica's potential as a source and reservoir for hydrocarbons (oil and natural gas) has become an important topic in Ohio. If the Utica contains large amounts producible of oil and gas, the economic impact on the state could be very significant. Due to its hydrocarbon generating potential, there is a great amount of ongoing research focusing on the Utica. Most of this investigation targets the Utica in Eastern Ohio since geologic factors in the area (history of oil and gas production, the unit resides within a window of ideal formation depth below the surface) and preliminary explorations indicate a high likelihood that producible amounts of hydrocarbon reside in the formation in that part of the state. Similar factors (though not as ideal) may exist in the Northwestern portion of the state, however little research has considered this area. The purpose of this study was to investigate the hydrocarbon potential of the Utica Shale in Northwestern Ohio by measuring TOC values of rock samples from the area, and investigating how these values vary throughout the area. Total Organic Carbon, more commonly referred to as TOC, is one important indicator of a geologic units potential as a source rock. It is a measurement of the concentration of organic material in a rock which is necessary for the generation of hydrocarbons. TOC measurements from the Utica in Northwest Ohio were obtained by acidifying rock samples from the Utica in the study area to remove Inorganic Carbon from the samples followed by combusting them in an Elemental Analyzer which measured the remaining, and thus organic, Carbon. 34 samples were obtained from 16 wells in 10 counties of Northwest Ohio. Results showed limited hydrocarbon potential for the area. The average TOC was 1.38% and the 34 samples ranged from 0.73 to 2.75% TOC with the majority of samples falling between 1 and 2%. No strong trends in the variability of the TOC by location were identified. Future research following the same methodology with a larger sample area or a closer-spaced sample frequency across the study area could reveal trends that were too broad or narrow to be identified by measuring the sampled wells.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas from shales is growing in importance with the development of technology that allows improved natural gas production. Devonian shales from the Appalachian Basin are recognized for their significant natural gas potential. The Marcellus Shale Formation is the lowest unit of the Devonian age from Hamilton Group and consists primarily of black shales high in organic carbon. Subunits of The Marcellus Formation have been studied to assess the abundance of the organic matter and type in the shale. The Oatka Creek Member of the Marcellus Formation was chosen for this study because of its high gamma ray log response, which corresponds to increased Uranium content, and the presence of organic carbon enrichment. Few data are available on this unit because much of the focus has been on the lower part of the Marcellus Formation (The Union Springs Member). Additionally, the distinct Kačák-Otomari bioevent is thought to have had a big influence on black shale deposition globally within the interval of Oatka Creek Member's deposition. For this study, The Bald Eagle and Bilger cores of the Oatka Creek Member were analyzed to assess the effect of The Kačák-Otomari event on sedimentation in the Appalachian Basin, and to examine the organic carbon content and the sources that affected the organic carbon deposition in the cores.Total organic carbon (TOC) content and carbon stable isotopic values of The Bald Eagle and Bilger cores from Pennsylvania were determined after crushing and decarbonation steps. Based on these analyses, TOC content in the Bald Eagle Oatka Creek Member (692 to 780 ft) varies between 1.19 and 4.65 %, whereas the TOC content of the Bilger Oatka Creek Member (160 to 250 ft) varies between 0.21 and 2.8 %. The [delta]13Corg values in the Bald Eagle core have a narrow range of -29.1 to -29.9 [per mille symbol] (PDB) whereas the [delta]13Corg values for the Bilger core have a relatively wider range of -25.6 to -29.9 [per mille symbol] (PDB). The organic carbon content in the Bald Eagle core is much higher than that in the Bilger core, and the lithofacies of the Oatka Creek Member suggest less overall dilution and/or oxygenation at the location of the Bald Eagle core. Kačák-Otomari bioevent didn't have much influence in both of the cores because of the lack of significant isotopic trend excursions. Because the [delta]13Corg pattern of Bald Eagle core is uniform and depleted in BC, this study suggests the dominance of amorphous marine organic matter at that location whereas in Bilger core marine organic matter gives way upward to increasing terrestrial organic matter input indicated by the trend towards more enriched [delta]13Corg values. This study establishes a base line for the organic carbon content and stable isotopic trends of the Bald Eagle and the Bilger cores. The comparison between these two cores helps interpretations for the general characteristics of the cores and the organic carbon enrichment throughout the whole zone.

Book Synopsis Geochemistry of the Marcellus Shale by : Thomas R. Malizia
Download or read book Geochemistry of the Marcellus Shale written by Thomas R. Malizia and published by . This book was released on 2011 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma ray (GR) spectroscopy is commonly used to map the organic-rich facies of hydrocarbon source rocks and a constant or basin-wide correlation between GR response and total organic carbon (TOC) content is often assumed. However, in the economically significant Devonian shales of the Appalachian Basin, such as the Marcellus shale, there is a notable variability in the GR response, while TOC concentrations remain fairly consistent. GR response, which is mainly due to a decrease in uranium, is appreciably reduced in the Upper Devonian shales: Dunkirk, Pipe Creek, Rhinestreet and Middlesex, compared to that in the Marcellus shale, while TOC concentrations remain consistent. This research investigates the influence of major, minor and trace element geochemistry on the GR response of these Devonian shales. It is hypothesized that GR response may be influenced by changes in ionic abundances, particularly carbonate and phosphate, which affected the solubility, sorption, and reduction of uranium. The hypothesis is tested by systematically investigating the association of uranium with mineral and organic fractions of Marcellus shale outcroppings and core samples from the western and northern edge of the Appalachian Basin. X-ray Absorption Spectroscopy (XAS) was used to attempt to identify the valency of uranium in the shale with the greatest GR response. These results should be valuable in interpreting GR response in the Appalachian Basin and in other black shale hydrocarbon deposits.

Book Synopsis Organic Matter Accumulation by : Elisabeth Lallier-Verges
Download or read book Organic Matter Accumulation written by Elisabeth Lallier-Verges and published by Springer. This book was released on 1995-06-20 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accumulation of organic matter allows inferences about a wide selection of processes in the geological past. The Kimmeridge Clay Formation (Yorkshire, U.K.) can be regarded as a model of the formation of hydrocarbon source rocks. The driving force of organic matter accumulation is the organic phytoplankton productivity, whereas oxygenation conditions seem to have played a secondary role. In Lake Bouchet (French Massif Central) organic matter appears to be a good indicator of paleoenvironmental changes occurring for over 350000 years. The book is of special interest to geologists and geochemists interested in organic matter accumulation.
Book Synopsis Chemical Biomarkers in Aquatic Ecosystems by : Thomas S. Bianchi
Download or read book Chemical Biomarkers in Aquatic Ecosystems written by Thomas S. Bianchi and published by Princeton University Press. This book was released on 2011-02-28 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way. This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists. Provides a guide to the broad diversity of chemical biomarkers in aquatic environments The first textbook to be structured around the compounds themselves Describes the structure, biochemical synthesis, analysis, and reactivity of each class of biomarkers Offers a selection of relevant applications to aquatic systems, including lakes, rivers, estuaries, oceans, and paleoenvironments Demonstrates the utility of using organic molecules as tracers of processes occurring in aquatic ecosystems, both modern and ancient
