Claim 1
Independent Claim
164 words
THE METHOD OF PRODUCTION OF HYDROCARBON MATERIALS FROM A FORMATION CONTAINING HIGH VISCOSITY, HIGH BOILING POINT PETROLEUM HYDROCARBONS DEPOSITS, WHICH FORMATION IS PENETRATED BY AT LEAST TWO WELLS, COMPRISING: INJECTING THROUGH ONE OF SAID WELLS INTO ONLY A PORTION OF SAID FORMATION NEAREST THAT WELL LOW VISCOISTY HYDROCARBONS HAVING AS MAJOR CONTENTS (A) HYDROCARBONS HAVING A BOILING RANGE OF APPROXIMATELY 350* F. TO 650* F. AT THE OPERATING ELEVATED PRESSURE OF A CONDENSATION ZONE IN CONTEMPLATED LATER BURNING OF THE FORMATION AND (B) LOW VISCOSITY HYDROCARBONS HAVING A BOILING RANGE OF APPROXIMATELY 100* F. TO 350* F. AT THE OPERATING ELEVATED PRESSURE OF A CONDENSATION ZONE IN CONTEMPLATED LATER BURNING OF THE FORMATION; AND THEREAFTER INJECTING INTO SAID WELL AN OXYGEN-C0NTAINING GAS AND SUPPORTING THEREBY COMBUSTION OF CARBONANACEOUS MATERIAL IN SAID FORMATION WITH CONTINUOUS PROGRESSION OF THE COMBUSTION TOWARDS THE OTHER OF SAID WELLS AND REMOVAL OF PRODUCTS FROM THE LATTER, SAID COMBUSTION BEING CARRIED OUT UNDER SAID ELEVATED PRESSURE CONDITIONS IN THE FORMATION.
