Well stream compression system

A compression system for a well stream production site, the compression system operable to facilitate extracting a production fluid from a well, the compression system comprising:

• a compressor;
• a separation unit positioned upstream from the compressor, the separation unit including a pressure vessel operable to separate the production fluid, or a fluid stream derived from the production fluid, into a gas phase stream and a liquid phase stream;
• a first line configured to receive the gas phase stream from the separation unit, the first line connected to a suction line of the compressor at a junction;
• and
• a second line configured to receive the liquid phase stream from the separation unit, the second line connected to the junction such that the gas phase stream flowing through the first line mixes with the liquid phase stream flowing through the second line at the junction to form a compressible fluid stream that is directed toward the compressor via the suction line.

A method of operating a production system for a production fluid, the method comprising:

• channeling the production fluid from a well toward a compression system that includes a compressor and a separation sub-system upstream from the compressor;
• separating, via the separation sub-system, the production fluid, or a fluid stream derived from the production fluid, into a gas phase stream and a liquid phase stream;
• channeling, via a first line, the gas phase stream toward a suction line of the compressor;
• channeling, via a second line, the liquid phase stream toward the suction line of the compressor, wherein the gas phase stream and the liquid phase stream are mixed at or upstream from the suction line into a compressible fluid stream;
• and
• controlling flow of the gas phase stream in the first line and the liquid phase stream in the second line toward the suction line to thereby control a gas-to-liquid ratio of the compressible fluid stream.
