Abstract

Simulation of a steam drive pilot in the South Belridge Diatomite, Kern County, California, indicated an increase in oil production. The upper injection hydrofracture was found to be highly dynamic and asymmetrical while undergoing steam injection. Steam flowed preferentially into the northern wing of the hydrofracture which reached a final wing length of 250 feet. To the south, hydrofracture wing length reached roughly 75 feet and diatomite heating was weak. Roughly 43 percent of the total injected steam migrated above the perforations of the injection well, but remained within the diatomite and flowed rapidly away from the fracture face due to a large increase of hydraulic diffusivity of the formation.
