Abstract
A method for treating a volume of porous contaminated material is described. A combustible mixture (24) comprising a porous matrix and a distributed combustible contaminant is conveyed to a reaction vessel (12) having an ignition system (16). The ignition system is activated to initiate a smoldering combustion process in the reaction vessel and an oxidizer is distributed into the reaction vessel to sustain the smoldering combustion process. The porous matrix may comprise drill cuttings (324) with residual drilling fluid.
