Abstract: A pneumatic valve 300 includes flexi-seals 302 that are annular shaped with non-circular cross-section and are fitted in peripheral groves in plunger 304 of the valve such that a portion of the flexi-seal 302 projects out of the outer circumference of the plunger 304. As the plunger 304 is moved towards a valve seat 314, the projecting portion of the flexi-seal 302 rests against a flat surface of the valve seat 314 to close the passage through the valve seat. The flexi-seal design prevents plurality of bends in the flow passages of the pneumatic valve 300, results in reduced friction during the linear movement of the plunger 304, eliminates movement of seals over edges of cross holes in the plunger bore 306. Besides the flexi-seals are flexible, do not permanently deform, and do not require lubricating media.

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.
