Claim 0:
1. A method comprising:
providing an offshore facility comprising a gas turbine, and a gas separator;
producing a produced gas from a gas reservoir to the offshore facility;
combusting the produced gas in a gas turbine to produce power and a flue gas;
at least partially removing nitrogen from the flue gas in a gas separator to produce a carbon dioxide-enriched flue gas and a nitrogen-enriched flue gas;
reforming a portion of the produced gas to produce a stream comprising hydrogen and carbon dioxide;
at least partially separating the carbon dioxide from the stream to yield a carbon dioxide stream and a hydrogen stream;
reacting the hydrogen stream and the nitrogen-enriched flue gas to yield ammonia;
combining and compressing the carbon dioxide stream and the carbon dioxide-enriched flue gas in a gas compressor to produce a compressed gas; and
injecting the compressed gas from the gas compressor into the gas reservoir, wherein at least some of hydrocarbon in the produced gas is combusted, reformed, and/or injected into the gas reservoir.
