First Claim
1. PROCESS FOR PRODUCING AND MAINTAIING ELEVATED PRESSURE WITHIN AN UNDERGROUND FLUID HYDROCARBON FORMATION HAVING A GAS PHASE WHEREBY INCREASED RECOVERY OF FLUID HYDROCARBON IS OBTAINED FROM A PRODUCTION WELL, COMPRISING WITHDRAWING A GASEOUS HYDROCARBON STREAM FROM SAID UNDERGROUND FORMATION, CATALYTICALLY REACTING SAID GASEOUS HYDROCARBON STREAM WITH STEAM AT ELEVATED TEMPERATURE TO PRODUCE A HOT GASEOUS PRODUCT STEAM PRINCIPALLY COMPRISING CARBON MONOXIDE AND HYDROGEN, COOLING SAID HOT GASEOUS PRODUCT STREAM BY INDIRECT HEAT EXCHANGE WITH WATER WHEREBY STEAM IS GENERATED, COMPRESSING SAID COOLED PRODUCT STREAM IN MECHANICAL COMPRESSION MEANS TO AN ELEVATED PRESSURE, DISCHARGING SAID COMPRESSED PRODUCT STREAM INTO SAID UNDERGROUND FLUID HYDROCARBON FORMATION THROUGH AN INJECTION WELL SPACED FROM SAID PRODUCTION WELL, WHEREBY ELEVATED PRESSURE IS PRODUCED AND MAINTAINED IN SAID FORMATION, AND EXPANDING SAID GENERATED STEAM THROUGH POWER PRODUCING MEANS CONNECTED TO SAID COMPRESSION MEANS, WHEREBY SAID GENERATED STEAM PROVIDES AT LEAST A PORTION OF THE POWER REQUIREMENT OF SAID COMPRESSION MEANS.
