DESCRIPTION APPLICATION
- flowing well operation;
- pumping of wells with high gas ratio;
- mixed well operation (start up with a pump and flowing operation after the pump is shut down).
ADVANTAGES
- large passage area across the valves allows the pump unit to operate in its normal mode as well as with a closed annulus;
- allows well operation in the flowing mode with the pump equipment tripped in;
- the valves generate harmonic oscillations of the bottomhole pressure and increase well flow rates;
- in combination with the ESP Unit it allows to operate wells with high gas ratio (up to several thousands of m3/m3) – an engineering calculation is required.
DESIGN FEATURES
- valve has a rotating body with a slot for the submersible electric equipment cable;
- flowing capacity doesn’t decrease in any position of its body.
TESTIMONIALS
- Under-control operation completion certificate from TPP “Uraineftegaz”
- Testimonial from “Gazpromneft-Vostok” Ltd.
