Interpretation of steam drive pilots in the belridge diatomite

摘要

The South Belridge Diatomite Field contains more than 2.5 billion barrels of oil-in-place. Current primary and waterflood develoment are estimated to recover only a small fraction of this oil. Despite it's low permeability, the diatomite may be a good candidate for the steam drive process, due to its thick oil column (1,000 ft), high porosity (50
