Through-tubing simultaneous gas and liquid production method and system

A system comprising:

• a production tubing extending from a wellhead at a surface into a well, the production tubing positioned in the well to form an annulus between the production tubing and the well;
• a coiled tubing extending from the wellhead at the surface into the production tubing, the coiled tubing arranged within the production tubing to form a first flow path within the coiled tubing and a second flow path between the coiled tubing and the production tubing;
• a pump disposed within the production tubing, the pump having a discharge end fluidly connected to the first flow path;
• a seal receptacle attached to a distal end of the production tubing;
• a seal adapter received within the seal receptacle, the seal adapter having a bore to receive a fluid mixture stream from a portion of the well below the production tubing;
• at least one seal element disposed between the seal receptacle and the seal adapter to isolate the second flow path from the portion of the well below the production tubing;
• and
• a gas separator positioned to receive a fluid mixture stream from the third flow path, the gas separator having a separation chamber in which the fluid mixture stream is separated into a gas stream and a liquid-rich fluid stream with a free gas content that is lower than that of the fluid mixture stream, the gas separator having at least a first passage to direct the gas stream into the second flow path and at least a second passage to direct the liquid-rich fluid stream into the pump.

A method comprising:

• disposing a first tubing in a well;
• disposing a second tubing within the first tubing to form a first flow path within the second tubing and a second flow path between the second tubing and the first tubing;
• fluidly connecting a discharge end of a pump to the first flow path;
• fluidly connecting a gas separator to the pump and the second flow path;
• isolating the second flow path from a portion of the well below the first tubing;
• receiving a fluid mixture stream from the well inside the gas separator;
• by the gas separator, separating the fluid mixture stream into a gas stream and a liquid-rich fluid stream with a free gas content that is lower than that of the fluid mixture stream;
• and
• simultaneously producing the gas stream and the liquid-rich fluid stream to the surface by directing the gas stream from the gas separator into the second flow path and directing the liquid-rich fluid stream from the gas separator into the pump while operating the pump.
