Abstract
A method for heat injection into a subterranean diatomite formation is provided. A heater is placed in a wellbore within the diatomite formation, and the heater is then operated at a temperature above that which the heater could be operated at long term in order to better sinter the formation in the vicinity of the wellbore. The improved sintering of the diatomite significantly improves the heat transfer coefficient of the diatomite and thereby increases the rate at which heat can be injected from a constant limited long term heater temperature.
