A METHHOD FOR PROCESSING NATURAL GAS WHICH COMPRISES (A) TRANSMITTING NATURAL GAS THROUGH A GAS TRANSMISSION LINE FROM A GAS PRODUCING AREA TO A GAS MARKETING AREA; (B) WITHDRAWING A PORTION OF THE GAS PASSING THROUGH SAID TRANSMISSION LINE AT AN INTERMEDIATE POINT BETWEEN SAID GAS PRODUCING AREA AND SAID GAS MARKETING AREA AND EXTRACTING ETHANE AND HIGHER HYDROCARBONS FROM THE GAS WITHDRAWN FROM SAID TRANSMISSION LINE; (C) PASSING THE ETHANE AND HIGHER HYDROCARBONS EXTRACTED FROM THE GAS WITHDRAWN FROM SAID TRANSMISSION LINE TO AN OIL FIELD FOR USE IN AN OIL RECOVERY OPERATION; (D) COMPRESSING THE DRY GAS REMAINING AFTER ETHANE AND HIGHER HYDROCARBONS HAVE BEEN EXTRACTED FROM THE GAS WITHDRAWN FROM SAID TRANSMISSION LINE AND INJECTING SAID DRY GAS INTO A GAS STORAGE RESERVOIR DURING PERIODS OF LOW DEMAND FOR GAS; (E) RECOVERING COMPRESSOR COMBUSTION GASES PRODUCED IN THE COMPRESSION OF SAID DRY GAS, EXTRACTING CARBON DIOXIDE AND HYROGEN SULFIDE FROM SAID COMBUSTION GASES, AND PASSING THE EXTRACTED CARBON DIOXIDE AND HYDROGEN SULFIDE TO SAID OIL FIELD FOR USE IN SAID OIL RECOVERY OPERATION DURING PERIODS OF LOW MARKET DEMAND FOR GAS; (F) RETURNING THE DRY GAS REMAINING AFTER ETHANE AND HIGHER HYDROCARBONS HAVE BEEN EXTRACTED FROM THE GAS WITHDRAWN FROM SAID TRANSMISSION LINE TO SAID TRANSMISSION DURING PERIODS OF HIGH MARKET DEMAND FOR GAS; (G) WITHDRAWING GAS FROM SAID GAS STORAGE RESERVOIR, COMPRESSING THE GAS WITHDRAWN FROM SAID RESERVOIR, TREATING THE GAS WITHDRAWN FROM SAID RESERVOIR FOR THE EXTRACTION OF CARBON DIOXIDE AND HYDROGEN SULFIDE, AND PASSING THE TREATED GAS TO SAID GAS MARKETING AREA DURING PERIODS OF HIGH MARKET DEMAND FOR GAS; AND (H) RECOVERING COMPRESSOR COMBUSTION GASES PRODUCED IN THE COMPRESSION OF SAID GAS WITHDRAWN FROM SAID STORAGE RESERVOIR, EXTRACTING CARBON DIOXIDE AND HYDROGEN SULFIDE FROM THE RECOVERED COMBUSTION GASES, AND PASSING THE EXTRACTED CARBON DIOXIDE AND HYDROGEN, TOGETHER WITH CARBON DIOXIDE AND HYDROGEN SULFIDE EXTRACTED FROM SAID GAS WITHDRAWN FROM SAID GAS STORAGE RESERVOIR, TO SAID OIL FIELD FOR USE IN SAID OIL RECOVERY OPERATION DURING PERIODS OF HIGH MARKET DEMAND FOR GAS.
