Industry Experience

OilTracers LLC, Dallas, Texas:

Senior Project Geochemist. Interpretation of geochemical data in order to evaluate source rock potential and reservoir properties such as fluid quality, continuity, fluid allocation and producibility. (2004-present).

ChevronTexaco Exploration Research Technology Company, San Ramon, California: Staff Geochemist. Integrated geochemical and geological data to determine lateral and vertical reservoir continuity, oil quality, and oil producibility. Work focused primarily on West African business units. (Congo, Angola and Nigeria). Carried out in-depth studies on the quantity, solubility, and mobility of reservoir bitumen for Cabinda, Angola oil field depletion models. (2002-2003).

Chevron Nigeria LTD, Exploration, Lagos, Nigeria:

Laboratory Supervisor. Supervised geochemists, palynologist, and technicians. Maintained analytical equipment in a remote location for the analysis of oils (gas chromatography, liquid chromatography, gas chromatography-mass selective detector), and waters (titration, ion chromatography, inductively coupled plasma spectrophotometer). Mentored Nigerian geochemist. Interpreted source rock, oil, water, and gas data in order to reduce exploration and production costs, determine spill origin, and meet environmental standards. (1998-2002).

Chevron Overseas Petroleum Inc., Exploration Technology, San Ramon, California:

Senior Geochemist. Integrated geochemical and geological data in order to determine lateral and vertical reservoir continuity and oil producibility. Studies involved West Africa, United Kingdom, Kazakhstan, and South America business units. Evaluated the quantity, solubility, and mobility of reservoir bitumen in several Cabinda, Angola oil fields. Monitored steam flood production in several San Joaquin Valley oil fields. Researched the capability of oils to become overprinted when contacting immature organic matter during migration. (1990-1998).

Chevron USA, Western Region, Development Geology, San Ramon California:

Geochemical Laboratory Project Coordinator. Maintained source rock evaluation instrumentation (Rock-Eval, Leco TOC) and oil analysis equipment (gas chromatography). Supervised and trained technical personnel. Interpreted source rock and reservoir geochemistry data. Worked extensively with oils from San Joaquin Valley Antelope and diatomite reservoirs and offshore California Monterey Formation reservoirs. Carried out numerous production allocation projects in San Joaquin Valley oil fields. (1986-1990).

Chevron Oil Field Research Company, Geology Division, La Habra, California:

Research Geochemist. Interpreted source rock and reservoir geochemistry data for overseas and domestic business units. Participated with others in the development of oil correlation software, gas chromatography hardware, and prediction of oil quality in Saudi Arabian reservoirs. Trained Chevron personnel in source rock and oil correlation analysis in Saudi Arabia and Bakersfield, California. (1984-1986).

Research Technician. Operated analytical equipment and carried out wet chemical procedures associated with source rock evaluation, oil quality evaluation, and oil correlation. Participated in development of new gas chromatography columns and sulfur gas chromatography using electron capture detection. Participated in the field trial of the first Rock Eval and consulted with the US manufacture of Rock-Eval II. Participated in development of various pyrolysis techniques including hydrous pyrolysis. (1973-1984).

Additional Experience and Credentials

Society Memberships: Member of AAPG

Other: Received special recognition award for leading a team to enhance trust between Chevron Nigeria Ltd employees and junior and senior oil worker unions (NUPANG and PENGASSAN) with CNL management (2002). Brooks retired from Chevron in September-2003. He and his wife, Bobi, have spent ten months completing a new home in the foothills of Sierra Nevada Mountains.
