ABSTRACT:
A process to recover oil is provided wherein an oil containing subterranean formation is heated by conductive heat transfer from heat injectors operating at temperatures above 900.degree. C. The high temperature levels of this process result in high recoveries of initial oil in place, and recovery of the oil within a short time period. This process is particularly applicable to diatomite formations that have low permeabilities.
