... in the North Sea. In South Belridge field the Belridge diatomite member of the late Miocene Reef Ridge Shale has proven prone to compaction during production. The reservoir, a high porosity, low permeability, highly compressive rock composed largely of diatomite and mudstone, is about 1000 ft thick and lies...

The first experiment is a complex multilayer example which closely models materials found in the extensive diatomite reservoir of Belridge field. For this numerical experiment, porosity changes dynamically due...

... decreases due to the increased abundance of nonopaline minerals, was espoused by Schwartz (1988) to explain similar trends in diatomites of the South Belridge field in the San Joaquin Valley. Mechanical compaction of rock can also act to reduce porosity. For example, smooth changes in porosity...

..., the central basin portion of the Reef Ridge Member contains thick sections of diatomite and diatomaceous shales, commonly referred to as the Belridge Diatomite Member. These diatomites are included as a facies in the Reef Ridge Member in this paper ( Figure 5 ), following Bandy and Arnal (1969) and Dibblee...

... diatomite zones ( Dale et al., 1996 ). As oil is removed, water commonly comes in to fill the void, and it is common for water–oil ratios (WORs) to increase over the life of an oil field. In the Belridge oil fields, the WOR increased from 0.09 in 1931 to approximately 14 in 2016, and in Lost Hills...

However, since this diatomite facies has not as yet been clearly differentiated from the typical Reef Ridge shale lithology into which it grades laterally, this diatomite and a similar one...

as upper Mohnian Delmontian Belridge Member ( Dibblee, 1973 , Figure 9 ), it is clear that there is no time significance to this diagenetic boundary in Temblor Range. Instead, uplift along San Andreas fault has prevented parts of section from being buried deeply enough for diagenetic conversion to take
