摘要:
Methods of generating subsurface heat for treatment of a hydrocarbon containing formation are described herein. Methods include providing water through one or more wellbores to at least a portion of a hydrocarbon containing formation and combusting at least a portion of a fuel stream comprising hydrogen sulfide in the presence of an oxygen source in one or more heaters positioned in one of the wellbores to produce a combustion by-products stream. Heat from the combustion is transferred to a portion of the hydrocarbon containing formation. The combustion by-products stream includes one or more sulfur oxides. Heat of solution is released by contacting at least a portion of the combustion by-products stream with a portion of the water and/or a portion of water in the hydrocarbon containing formation.

Methods for treating a hydrocarbon containing formation are described herein. A comprising hydrogen sulfide is combusted in one or more surface facilities exterior to the hydrocarbon containing formation to produce a sulfur oxides stream. At least a portion of the sulfur oxides stream is provided to a hydrocarbon containing formation. Steam may be provided to the hydrocarbon containing formation. Mixing of the steam and/or water in the formation with the sulfur oxides generates heat of solution in the hydrocarbon containing formation for mobilizing formation fluids.

Methods of generating subsurface heat for treatment of a hydrocarbon containing formation are described herein. Methods include providing steam to at least a portion of a hydrocarbon containing formation from a plurality of locations in a wellbore. The steam is hotter than a temperature of the portion. The steam is heated in the wellbore by combusting a stream comprising hydrogen sulfide in the wellbore. Heat from the combustion transfers to the steam. The steam provided the portion at a first location in the wellbore is hotter than steam provided at a second location in the wellbore along the length of the wellbore, where the first location is further from a surface of the formation than the second location along the length of the wellbore.

A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a metal-containing non-acidic catalyst at a temperature of 375° C. to 500° C. to produce a vapor comprising a first hydrocarbon-containing product.
