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

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.
