1. A method for increasing recovery of hydrocarbon-containing organic matter from a production well coupled to a hydrocarbon-containing sub-surface formation, the subsurface formation comprising hydrocarbon-containing material, the method comprising the steps of extracting the hydrocarbon-containing organic matter by a process comprising:
- providing an injection well, said injection being in fluid communication with the sub-surface formation;
providing a substantially surfactant-free first liquid comprising non-aqueous hydrocarbon-extracting turpentine liquid;
injecting the non-aqueous hydrocarbon-extracting turpentine liquid through the injection well and into the formation, wherein the non-aqueous hydrocarbon-extracting turpentine liquid and the hydrocarbon-containing organic matter from the hydrocarbon containing sub-surface formation form an extraction mixture comprising at least a portion of the hydrocarbon-containing organic matter extracted into the non-aqueous hydrocarbon-extracting turpentine liquid;
recovering the extraction mixture from the formation through the production well; and
separating the extraction mixture to produce a hydrocarbon product stream and a hydrocarbon-extracting liquid stream.

Abstract
A method of extracting hydrocarbon-containing organic matter from a hydrocarbon-containing material includes the steps of providing a first liquid comprising a turpentine liquid; contacting the hydrocarbon-containing material with the turpentine liquid to form an extraction mixture; extracting the hydrocarbon material into the turpentine liquid; and separating the extracted hydrocarbon material from a residual material not extracted.
