Abstract:
A method for producing surfactants from accumulations of constrained organics at a subsurface site in a subsurface reservoir, said method comprising:injecting steam and an oxidant into the subsurface site containing constrained organics to form a mixture containing predetermined portions of (a) condensed water from the stream and (b) the oxidant, water from the subsurface site and the constrained organics from the reservoir; allowing hydrous pyrolysis/partial oxidation of the mixture to produce surfactants that form an oil/water emulsion with a second portion of the constrained organics and condensed water from the steam and/or water occurring naturally in the reservoir; and removing the oil/water emulsion from the subsurface reservoir.
