Abstract
Oil sands and like host materials are leached with a selected leachant to render pumpable the oil (including heavy oil, bitumen or kerogen and asphaltenes) as leachate. In a preferred embodiment, natural deposits are in situ leached and the leachate recovered and removed for treatment. The leachant is separated and recycled. The leachant is selected to be biodegradable and to not precipate asphaltenes, and to comprise monoterpenes of the formula CH. The overall process allows environmentally acceptable resource development and contaminated site remediation.
