Biological Markers in Sediments and Petroleum by J.M. Moldowan, , available at Book Depository with free delivery worldwide. Biomarkers are individual organic constituents of sediments, sedimentary rocks and petroleums which derive from biological by: They are common in petroleum and recent to ancient sediments and are composed mainly of carbon and hydrogen but can include other elements, such as sulfur, nitrogen, vanadium, or nickel. Biomarkers are useful in petroleum exploration and production (Peters et al. ) as well as environmental forensics (Wang et al. ). The text is broken down into 4 chapters: (1) introduction to biological markers, (2) description of the fundamentals of biomarker separation analysis, (3) guidelines for interpretation, and (4.
Biological markers and organic petrology study of organic matter in the Lower Cretaceous Abu Gabra sediments (Muglad Basin, Sudan): origin, type and palaeoenvironmental conditions. ABSTRACT: Regular steranes occur ubiquitously in petroleum and hydrocarbon source rocks as an important composition part of biological markers. Abnormal regular sterane distribution occurring in hydrocarbon source rocks and crude oils has been widely reported in recent years, but their origin and genetic mechanism are unclear. In book: Analytical Advances Biological markers in the sedimentary record., Methods in Geochemistry. and Geophysics 24 Elsevier, Amsterdam, Petroleum and Ancient Sediments . Following important advances in identification of biological markers in sediments and crude oils, these markers are used for oil-source rock correlation, and proposed for reconstruction of depositional environment and subsequent thermal evolution.
Biomarkers or biological markers are the complex organic compounds which are comprised of carbon, hydrogen, and other elements. Biomarkers are usually found in oil, bitumen, rocks, and sediments, and they usually show little changes in terms of molecule structure from their parent organic molecules in living organisms. Petroleum. Petroleum source rocks represent uncommon paleoenvironrnents. Their organic content is a function of biological productivity, oxygenation in the water column and in near-bottom sediments (preservation), and mineral supply (dilution). Biological input varies from hydrogen-rich algal/bacterial constituents to hydrogen-poor woody fragments. The book comprises two parts: the first discusses the origins of various classes of biomarkers and how they can be applied to petroleum exploration problems. A number of examples of distributions from different types of crude oils and source rocks are provided, plus a summary of all the biomarker parameters used in exploration studies. An evaluation of the molecular analysis of the thermal history of sediments is also discussed in the book. Concepts such as the biological marker compounds, stereochemical conversion, and lower Toarcian sediments are covered in detail. Analysis of organic matters, such as acyclic isoprenoids, steranes, hopanes, and porphyrins, is highlighted.
