Petroleum System Geochemist

Job Description

Petroleum System Geochemist This role is for an early to mid-career petroleum geochemist to work alongside earth scientists and petroleum engineers to assess petroleum source rock presence, quality, and quantity. The position also involves characterizing and predicting hydrocarbon fluid phase and composition through integrated geochemical data analysis and interpretation. The insights gained will support exploration, asset development, and field optimization decisions. Responsibilities: Provide geochemistry expertise for exploration and development projects, including regional and prospect-scale assessments. Support well operations during exploration and development phases by analyzing geochemical data. Collaborate with internal and external laboratories to collect, process, and interpret geochemical data. Integrate geochemical findings with other subsurface datasets and present results for project reviews. Participate in research and technology development projects and contribute to knowledge-sharing through training sessions when needed. Travel to business units or third-party locations for consultations and technical work, as required. Work in cross-functional teams under tight timelines to deliver creative solutions across multiple projects. Required Qualifications: Masters or Ph.D. in Geochemistry or a related Geology sub-discipline with a focus on geochemistry. Strong background in sedimentology and organic chemistry. Solid understanding of petroleum source rock development in sedimentary basins, including oil and gas generation, migration, and alteration processes. Experience in analyzing and interpreting geochemical data in at least two of the following areas: Source rock evaluation (TOC, Rock-Eval, vitrinite reflectance, etc.). Gas data analysis (composition and isotopic data for hydrocarbon and non-hydrocarbon gases). Oil geochemistry data (API gravity, GOR, sulfur content, biomarkers, and isotopic composition). Ability to integrate geochemical data with geological and engineering datasets such as petrophysical data, seismic data, and PVT data. Demonstrated ability to learn quickly, think analytically, and apply learnings effectively. Strong collaboration skills with a proven ability to work under tight deadlines and manage multiple projects simultaneously.
