A plume of combined gases are infused into hydrocarbon-bearing formations, “inert” as the major gas and “reactive” as the minor gas, where the minor gas reacts with hydrocarbons to fully saturate hydrocarbons with supercritical fluid, which migrate hydrocarbons out of formations, even at great distances from the regulated fuel cell source. Coal, tar sands, petroleum-contaminated soil, and / or oil wells that have lost gas pressure can also be desorbed by this in-situ method.
