Vacancy for a research geochemist (petroleum geochemist)

Vacancy for a research geochemist (petroleum geochemist) with the USGS Energy Resources Program in Denver, Colorado USA.

U.S. Geological Survey (USGS)
Position Available
Research Geologist/Research Chemist (Petroleum Geochemist)
The USGS Central Energy Resources Science Center in Lakewood, Colorado is soliciting interest from qualified individuals for a Research Geologist or Research Chemist with comprehensive experience in organic geochemistry and petroleum geology as applied to the integration of geochemical and geological data in qualitative and quantitative assessments of conventional and unconventional petroleum resources, both domestically and around the world. Successful applicants must meet qualifying education requirements and have demonstrated expertise and substantial experience in organic geochemistry and petroleum geology to formulate and conduct research of fundamental interest and applicability to the Energy Resources Program goals. This work will lead to new hypotheses, concepts, analytical techniques, and a better understanding of geological and geochemical factors that control petroleum generation, migration, entrapment, and alteration. The incumbent is expected to manage an independent research program in one or more of the following areas: 1) controls on deposition and diagenesis of organic-rich rocks as related to petroleum source-rock generation and unconventional reservoir formation; 2) theoretical and experimental studies of the kinetics of petroleum generation; 3) petroleum expulsion, migration, and accumulation; 4) development and application of organic geochemical techniques for petroleum correlation studies (e.g., oil-oil, oil-source, etc.); 5) controls on the molecular and stable isotopic composition of hydrocarbon and non-hydrocarbon gases; 6) secondary alteration of petroleum (biodegradation, thermochemical sulfate reduction, etc.); and 7) applications of organic geochemistry in petroleum systems modeling and basin analysis. The research will likely require proficiency in conducting field and laboratory-based studies, as well as an in-depth understanding of the theoretical foundation of petroleum geochemistry. The position is supported by the research facilities of the Energy Resources Geochemistry laboratories that include: organic extraction and fractionation equipment; gas-chromatography and mass-spectroscopy instrumentation; elemental analysis and source rock pyrolysis (i.e., Rock-Eval); C, H, and N stable isotopic analysis of solids, liquids, and gases; and large-scale (hydrous pyrolysis) and small-scale (sealed tube) pyrolysis laboratories for experimental studies of high temperature and pressure reactions. Candidates must be able to work as part of a multidisciplinary team of geologists, geochemists, geophysicists, and engineers, and to contribute to petroleum resource assessment activities. Excellent writing and oral presentation skills are also required because candidates are expected to publish results of scientific studies in technical journals and USGS publications.
