1. An in situ heat treatment system for producing hydrocarbons from a subsurface formation, comprising:
- a plurality of wellbores in the formation;
at least one heater positioned in at least two of the wellbores; and
a self-regulating nuclear reactor configured to provide energy to at least one of the heaters to heat the temperature of the formation to temperatures that allow for hydrocarbon production from the formation, wherein a temperature of the self-regulating nuclear reactor is controlled by controlling a pressure of hydrogen supplied to the self-regulating nuclear reactor, and wherein the pressure is regulated based upon formation conditions.

Abstract
An in situ heat treatment system for producing hydrocarbons from a subsurface formation includes a plurality of wellbores in the formation. At least one heater is positioned in at least two of the wellbores. A self-regulating nuclear reactor provides energy to at least one of the heaters to heat the temperature of the formation to temperatures that allow for hydrocarbon production from the formation. A temperature of the self-regulating nuclear reactor is controlled by controlling a pressure of hydrogen supplied to the self-regulating nuclear reactor, and wherein the pressure is regulated based upon formation conditions.
