Abstract
An electrical submersible pump (ESP) completion is used in a reservoir. The ESP completion includes an ESP and a static mixer placed below an intake of the ESP within the reservoir. A two-phase (liquid-gas) mixture flows from the reservoir through a tubing-casing annulus to the static mixer. The static mixer conditions and homogenizes the two phase (liquid-gas) mixture. The mixture flows to a tubing-casing annulus through perforated joints to enter the intake of the pump.
Claims18
An electrical submersible pump (ESP) completion for use in a reservoir, the ESP completion comprising:
- an ESP disposed in the ESP completion, the ESP comprising a pump intake hydraulically connected to the ESP and a tubing-casing annulus;
- a static mixer disposed downhole from the pump intake configured to condition and homogenize a two-phase mixture from the reservoir to the ESP,
- wherein the two-phase mixture comprises liquid and gas flowing from the reservoir through the tubing-casing annulus into the static mixer;
- and
- a perforated joint disposed between the static mixer and the pump intake configured to hydraulically connect the static mixer to the tubing-casing annulus, such that the conditioned and homogenized two-phase mixture flows inside the tubing-casing annulus.
A method of using an electrical submersible pump (ESP) completion in a reservoir, the method comprising:
- placing a static mixer below a pump intake of an ESP in the ESP completion within a tubing-casing annulus;
- flowing a two-phase mixture from the reservoir through the tubing-casing annulus to the static mixer, wherein the two-phase mixture comprises liquid and gas;
- conditioning and homogenizing, via the static mixer, the two-phase mixture, and
- directing the conditioned and homogenized two-phase mixture into the tubing-casing annulus through a perforated joint to enter the pump intake of the ESP, such that the conditioned and homogenized two-phase mixture flows inside the tubing-casing annulus.
