1. A system for producing a multiphase formation fluid utilizing an electric submersible pump, the system comprising:
a subsurface formation comprising the multiphase formation fluid;
a surface collection point;
a wellbore extending from the surface collection point to the subsurface formation;
a packer positioned within the wellbore, the packer defining a first cavity and a second cavity, both the first cavity and the second cavity extending from a top surface of the packer to a bottom surface of the packer;
the electric submersible pump (ESP) comprising an ESP inlet end and an ESP outlet end, the ESP outlet end coupled to the bottom surface of the packer at the first cavity;
a gas separator comprising a multiphase formation fluid inlet, a gaseous phase outlet, and a liquid phase outlet, the liquid phase outlet coupled to the ESP inlet end;
a first tubing string coupled to the top surface of the packer at the first cavity, wherein the first tubing string, the ESP, and the gas separator together define a first fluid pathway from the multiphase formation fluid inlet to the surface collection point; and
a second tubing string coupled to the top surface of the packer at the second cavity, the second tubing string and the packer together defining a second fluid pathway from the bottom surface of the packer to the surface collection point, and wherein
the gas separator is configured to separate a gaseous phase of the multiphase formation fluid to produce the gaseous phase through the second tubing string to the surface collection point, and
the ESP is configured to produce a liquid phase of the multiphase formation fluid from the subsurface formation through the gas separator and the first tubing string to the surface collection point.
