California Well Sample Repository


click the photo for a larger imageWe are the only facility in California providing permanent storage and public use of cores, sidewall samples, drill cuttings, outcrop samples, microfaunal slides, foundation borings, and mineral suites. Our collection, started in 1975, is housed in two 6,000 ft2 buildings on the campus of the California State University at Bakersfield (CSUB).

Our catalog lists tens of thousands of core, cuttings, well logs, and paleontology samples that are available for view from the thousands of California oil, gas, water and core wells stored in our collection. This catalog, which is in Microsoft Excel (.XLS) format, is available for download from this website. You may also visit us in person, and you will find us on the west side of Roadrunner Drive, which is reached by entering the south gate of the CSUB campus from Camino Media Drive in Bakersfield.

Tuesday: 7:30am-9:00am
Wednesday: 7:30am-2:00pm
Thursday: 7:30am-9:00am

The day-to-day operation of the Repository is carried out by the curator, with volunteers and student employees. The Project Director, a member of the CSUB faculty, acts under guidelines and advice from the Advisory Committee, which supervises the facility. Grants, contracts, donations, gifts and other funds received in support of the Repository are administered by the California State University Bakersfield solely for the benefit of the Repository. The Foundation is a non-profit corporation established in 1969 to beneficially support projects and services of the State University, which are not provided through state university funding.

The Advisory Committee of the Repository establishes operating policies and procedures, and directs, advises, guides, and authorizes the general operation of the Repository. Membership on the committee has broad representation of those interested in use of the facility. Members currently include representatives from the California State University, California Division of Oil and Gas, State Lands Division, Division of Mines and Geology, Bureau of Land Management, major oil companies, independent oil companies, petroleum service companies, independent geologists and paleontologists, and engineers.
