The Biomarker Guide: Interpreting Molecular Fossils in Petroleum and Ancient Sediments
Kenneth E. Peters,J.M. Moldowan +1 more
TL;DR: In this paper, a comprehensive discussion of biomarkers and how they are used with other geochemical methods to reduce the risk associated with exploration for petroleum is provided, together with guidelines for the use of selected parameters.
Journal ArticleDOI
Effects of source, thermal maturity, and biodegradation on the distribution and isomerization of homohopanes in petroleum
Kenneth E. Peters,J.M. Moldowan +1 more
TL;DR: In this article, the C35-homohopane index decreases with increasing API gravity and thermal maturity of related oils from the Monterey Formation, offshore California, showing that identical heating conditions result in different homopane C-22 epimer ratios.
Journal ArticleDOI
Effects of hydrous pyrolysis on biomarker thermal maturity parameters: Monterey Phosphatic and Siliceous members
TL;DR: The behavior of isomerization-based biomarker ratios in these experiments is more complex than ratios based on carbon-carbon cracking or aromatization reactions as mentioned in this paper, but the results of the experiments are similar to those reported in this paper.
Journal ArticleDOI
Petroleum isotopic and biomarker composition related to source rock organic matter and depositional environment
TL;DR: A multivariate approach has been developed that separates oils derived from organic matter in non-marine shales, marine carbonates, and marine shales as mentioned in this paper, using C30-sterane and mono-aromatic steroid biomarker ratios.
Journal ArticleDOI
Origin of Beatrice Oil by Co-Sourcing from Devonian and Middle Jurassic Source Rocks, Inner Moray Firth, United Kingdom
TL;DR: In this paper, the authors demonstrate the power of a multiparameter geochemical approach in solving the difficult oil to source rock correlation problem, which can lead to the recognition of new exploration plays in previously well-explored basins.
