GEO ExPro - The Many Lives of Belridge

The original discovery pools, the Tulare Formation that contained heavy 11–15° API oil and the Monterey diatomite pool with its much lighter 25–39° crude were often completed together. This completion method would allow the light oil from the diatomite zone to dilute the heavy oil in the Tulare and allow economic production of the heavy oil.

Dec 17, 2006· Historical Production and Injection Rates (Figure 4) Depositional Environment of Diatomite (Figures 5 and 6) Diatomite is the term given to the unconventional rock composed predominantly of the biogenic siliceous deposits of diatoms. In California, this rock type is common in the Central Valley and coastal basins.

Production Process | Santa Maria Energy

Oil Production Process The Resource: Where it is and why it is there? The Sisquoc diatomite reservoir within the project area lies between 800 to 1200 feet below the surface. The formation consists of layers of diatoms, single cell marine animals which have been deposited over time in ancient sea beds.

Reasons for production decline in the diatomite, Belridge ...

This work summarized research conducted on diatomite cores from the Belridge oil field in Kern County. The study was undertaken to try to explain the rapid decline in oil production in diatomite wells. Characterization of the rock showed that the rock was composed principally of amorphous opaline ...
