THE METHOD OF OBTAINING DESIRABLE LIQUEFIABLE PETROLEUM HYDROCARBON FROM A PRODUCING FORMATION INCLUDING FLOWING THE GAS UNDER PRESSURE FROM THE FORMATION, COOLING THE GASE AT SUBSTANTIALLY THE PRESSURE OF THE FLOW FROM SAID FORMATION TO STRIP THE GAS BY CONDENSATION OF THE DESIRABLE LIQUEFLABLE HYDROCARBONS, REMOVING THE CONDENSATE FROM THE STRIPPED GAS, EXPANDING THE STRIPPED GAS TO A SUBSTANTIALLY LOWER PRESSURE, REFRIGERATING THE STRIPPED GAS TO EFFECT LIQUEFACTION OF THE STRIPPED GAS AND PUMPING THE STRIPPED LIQUEFIED GAS TO THE FORMATION AT A PRESSURE HIGHER
