California State Personnel Board Specification

  • Schematic Code: HW20
  • Class Code: 3800
  • Established: 09/24/1959
  • Revised: 08/04/1998
  • Title Changed: --


Under direction, to plan, organize, and perform subsurface geologic studies and investigations for the evaluation of petroleum production potential; to estimate volumes of oil and gas for utilization in petroleum reservoir engineering studies, reserve estimation, and equity determinations; and to do other related work.

Typical Tasks

Either as a project team leader or individually, may plan, organize, or direct the performance of subsurface petroleum geologic-reservoir engineering studies in connection with determination and location of oil and gas production potential and estimates of oil and gas in place; interprets electrical and radioactive logs, core analysis data, paleontological reports, geophysical information, petrographic information, and other geologic data; as a project team leader or individually, may perform the making of subsurface structural contour maps, thickness maps, distribution of net oil sand maps, lithofacies maps, fluid distribution maps, structural and stratigraphic cross- sections; makes studies of productive limits by structural analysis and original fluid distribution within the oil reservoirs; prepares technical reports relative to the use of subsurface geologic data for the purpose of augmenting petroleum reservoir engineering studies in primary and secondary recovery projects for reserve estimation and equity determination; makes studies and prepares reports on land subsidence; may represent the division in conferences with oil and gas producers, other State and Federal agencies, and local interests.

Minimum Qualifications

Experience: Five years of progressively responsible petroleum geologic or petroleum engineering experience, including at least two years of experience in subsurface petroleum geology for exploration or for secondary recovery projects. and Education: Equivalent to graduation from college with major work in petroleum geology, petroleum engineering, or a closely related field. (Additional qualifying experience may be substituted for the required education on a year-for-year basis.)

Knowledge and Abilities

Knowledge of: Petroleum engineering/geological methods and survey techniques; historical geology as related to development of structure and void volumes in petroleum reservoir engineering; subsurface mapping and the application of subsurface geology to petroleum engineering problems; subsurface exploration techniques and sampling and data gathering procedures; geologic literature.


Ability to: Interpret data and prepare reports; carry on independent technical work; provide leadership and direction to project teams; communicate effectively and establish and maintain cooperative relations with those contacted in the work.

Additional Desirable Qualification

Registration as a Geologist under the California Geologist and Geophysicist Act.
