California Well Sample Repository

 

We 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.

We are open:  
Monday: 7:30am-2:00pm
Tuesday: 7:30am-9:00am
Wednesday: 7:30am-2:00pm
Thursday: 7:30am-9:00am
Friday: closed

You can also email our curator, or call him at (661) 654-2324 for more information.

 

 

HISTORY

1975
Founding of the California Well Sample Repository on July 24, 1975 by Jim Weddle, Ed Sprotte, Jack Coash and Vic Church to save the cores of ~850 Superior Oil Company wells from being destroyed, and to preserve these cores for study by academia and industry.
 
1976
Dedication in March 1976 of a 6,000 ft2 building for the Repository on the campus of Calif. State Univ. at Bakersfield. Lawrence "Jack" Tucker hired on as curator.
 
1978
The first major event at the Repository is a Stevens Core Workshop held on May 12 & 13, 1978 with a subsequent publication. (Click at right to see photos of the event)
 
1984
Funding is obtained for construction of a second 6,000 ft2 building for the Well Sample Repository to be erected behind the original building.
 
1988
To honor Jack Tucker (1920-1987) for his 11 years of service as curator, the front of the Repository is landscaped and a memorial plaque placed bearing Jack's name. Also, curator Larry Knauer begins recruiting senior volunteers to assist at the facility.
 
1998
Jim Weddle, a founding Director and Chairman of the Advisory Committee to the Well Sample Repository, retires after serving for 23 years.
 
1999
The Repository establishes an internet presence with a website at www.wellsample.org.
The old website was crude by modern standards, but cutting edge for the time.
 
1999
Dedication on Nov. 17, 1999 of a memorial to founding Director Vic Church in recognition of his years of service to the Well Sample Repository. Vic's memorial, which stands on the southeast side of the Repository, is a 36-inch core from the footing of Friant Dam.
 
Today
The California Well Sample Repository today preserves the cores and cuttings from over 8,000 wells, and over 200,000 well logs and files.
