Abstract
A technique for facilitating the movement of multi-phase fluids. The technique utilizes a compressor pump and a production pump. The compressor pump compresses a fluid to remove vapor phase and then discharges the pressurized fluid to a production pump. The production pump produces the pressurized fluid to a desired location with greater efficiency due to reduction of the vapor phase.
Claims40
A production system designed for use in a wellbore to produce a fluid, comprising:
- a modular electric submersible pumping system having:
- a submersible motor;
- a submersible pump powered by the submersible motor;
- and
- a helico-axial compressor pump independent from the submersible pump, the helico-axial compressor pump being positioned upstream from the submersible pump.
A pumping system, comprising:
- a centrifugal pump having a centrifugal pump housing;
- and
- a helico-axial compressor pump having a helico-axial compressor pump housing, wherein the centrifugal pump housing and the helico-axial compressor pump housing are removably coupled together.
A production system disposed in a wellbore to produce a fluid, comprising:
- a submersible motor;
- a submersible production pump powered by the submersible motor;
- and
- a compressor pump positioned to pressurize a wellbore fluid to be produced by the submersible production pump, wherein the compressor pump generates less head than the submersible production pump.
A method of facilitating the production of a relatively high gas-to-liquid ratio fluid from a subterranean environment, comprising:
- drawing a wellbore fluid through a pump intake;
- pressurizing the wellbore fluid in a helico-axial pump;
- discharging the wellbore fluid to a separate production pump following pressurizing;
- and
- producing the wellbore fluid to a collection point.
A system of facilitating the production of a relatively high gas-to-liquid ratio fluid from a subterranean environment, comprising:
- means for drawing a wellbore fluid through a pump intake;
- means for pressurizing the wellbore fluid in a compressor pump;
- and
- means for discharging the wellbore fluid to a separate production pump following pressurizing.
