Downhole Separation Efficiency Technology to Produce Wells Through a Single String

A system for producing hydrocarbons from a subterranean well, the system comprising:

• a combined product tubular extending into the well and through a packer that fluidly seals across a casing of the well;
• a gas production tubular in fluid communication with the combined product tubular;
• a fluid production tubular in fluid communication with the combined product tubular;
• an electrical submersible pump in fluid communication with the fluid production tubular;
• a cyclone separator within the well, the cyclone separator having:
• a rotating screw with thread surfaces open to an inner diameter surface of the casing, the thread surfaces angled to direct a liquid stream radially outward towards the inner diameter surface of the casing and to direct a gas stream radially inward relative to the liquid stream;
• and wherein
• the thread surfaces of the rotating screw are angled to direct the gas stream towards a lower end of the gas production tubular;
• and
• a jet pump located at a junction of the gas production tubular, the fluid production tubular, and the combined product tubular, the jet pump powered by the liquid stream and oriented to inject the gas stream into the liquid stream.

A method for producing hydrocarbons from a subterranean well, the method comprising:

• extending a combined product tubular into the well;
• extending a gas production tubular and a fluid production tubular into the well, each of the gas production tubular and the fluid production tubular being in fluid communication with the combined product tubular;
• locating a jet pump at a junction of the gas production tubular, the fluid production tubular, and the combined product tubular;
• providing an electrical submersible pump in fluid communication with the fluid production tubular;
• providing a cyclone separator within the well, the cyclone separator having a rotating screw with thread surfaces open to an inner diameter surface of the well;
• and
• operating the cyclone separator so that the thread surfaces direct a liquid stream axially downward and radially outward towards the inner diameter surface of the well and direct a gas stream to a lower end of the gas production tubular.
