Abstract

Methods of generating subsurface heat for treating a hydrocarbon containing formation are described herein. The methods include providing a stream that includes water to a plurality of wellbores. Fuel and oxidant is provided to one or more flameless distributed combustors positioned in at least one of the wellbores. The fuel and oxidant is mixed to form a fuel/oxidant mixture. At least a portion of the mixture is flamelessly combusted in at least one of the flameless distributed combustors to generate heat. The fuel includes at least 0.1% hydrogen sulfide by volume.

Claims13

Dependent claims

A method of treating a hydrocarbon containing formation, comprising:

providing a stream comprising water to a plurality of wellbores positioned in a hydrocarbon containing formation;
providing a fuel stream and an oxidant stream to one or more flameless distributed combustors positioned in at least one of the wellbores, wherein the fuel stream has a hydrogen sulfide content of at least 0.1% hydrogen sulfide by volume as determined by ASTM Method D2420;
mixing at least a portion of the fuel stream and at least a portion of the oxidant stream to form a fuel/oxidant mixture;
and
flamelessly combusting at least a portion of the fuel/oxidant mixture in at least one of the flameless distributed combustors to generate heat.
