Standing Valves

Weatherford offers a McMurry-Macco® MP-1 pump-through standing valve, as well as the McMurry-Macco SV series.

MP-1 Pump-Through

This valve combines the downhole check capabilities of a traditional standing valve with the ability to backflow through the valve when necessary. This capability is ideal for performing downhole treatments, such as hot oiling, without having to pull the standing valve.

The MP-1 standing valve is used to prevent fluid backflow during intermittent gas-lift operations. This valve can also be used as a traditional check valve or to facilitate downhole treatment operations.

SV Series

These valves act as check valves to prevent the migration of fluid in tubing back into formation during intermittent gas-lift or plunger-lift operations. SV series valves serve as a pressure interface between production or load fluids and the formation. The SV-WE valves allow the operator to equalize the production formation pressure before pulling. The SV-WF valves are non-equalizing standing valves, designed to hold pressure from above while allowing fluids to flow from beneath the valve.
