Abstract
Thermal energy delivery and oil production arrangements and methods thereof are disclosed which heat a subterranean formation, and which comprises positioning concentric tubing strings in a wellbore; heating a heat transfer fluid using a surface thermal fluid heater; flowing a liquid or feedwater downward through an extremely hot innermost tubing string that is inside and concentric to an outermost tubing string and a casing/annulus, which extends below a thermal packer positioned in the wellbore, and continually circulating the heat transfer fluid through the outermost tubing string and the casing/annulus above the thermal packer such that the liquid or feedwater flowing through the innermost tubing string is heated thereby and injected into the wellbore below the thermal packer and out of perforations to heat the subterranean formation to temperatures that allow for hydrocarbon production from the subterranean formation. Emissions may be injected into the subterranean formation with the liquid or feedwater.
