1. An offshore facility comprising:
a crude oil production offshore facility having a crude oil processor for refining crude oil collected from a subsea well to produce oil;
a feed gas supplier including a first compressor for compressing an associated gas separated in the process of refining the crude oil for generating a first feed gas such that the associated gas has a first target pressure; and
a gas injector including a second compressor for generating an injection gas by compressing the associated gas compressed by the first compressor such that the compressed associated gas has a second target pressure higher than the first target pressure, and an injection line for reinjecting the injection gas into a reservoir;
a liquefied natural gas production offshore facility supplied with a feed gas from the feed gas supplier including at least a part of the associated gas from the crude oil production offshore facility, and processing and liquefying the feed gas to generate a liquefied natural gas,
wherein the feed gas supplier includes:
a feed gas supply line for transferring the feed gas to the liquefied natural gas production offshore facility;
a back-flow line branched from the injection line and joined to a feed gas supply line for recovering a back-flow gas which flows backward from the reservoir and includes at least a portion of the injection gas reinjected to the reservoir by the gas injector; and
a first decompressor for decompressing the back-flow gas to generate a second feed gas, and
wherein the feed gas comprises at least one of the first feed gas, the second feed gas, a third feed gas, and combinations thereof, decompressed from the injection gas.
