Reservoir ShutOff Valve
PetroQuip’s Reservoir ShutOff Valve is a flow actuated device that prevents fluid from flowing back into the formation when downhole flow is reversed. It is typically installed below an electric submersible pump (ESP) or artificial lift completion.
The Reservoir ShutOff Valve utilizes an industry standard safety valve flapper to create a fluid barrier and seal.
-
Significantly reduces kill fluid volume/cost during workover operations
Reduces rig time by maintaining static fluid level creating a down hole barrier
Reduces potential reservoir damage due to fluid loss
Less than 3 psi pressure drop at 2,000 BPD production
Normally open with all sealing surfaces protected from flow
Patent pending closing mechanism activated by reserve flow
Contingency bypass available upon request
-
Can be installed in new or existing completions
Installed above or below packer
Utilized in a SAG-D well to retain heat in the lateral
Does not hinder the use of a rupture disk for initial well suspension

How much kill fluid are you losing on every workover?
Hold your fluid level and protect the reservoir.
The Reservoir ShutOff Valve closes when flow reverses, creating a downhole barrier that reduces kill fluid volume, rig time and fluid loss to the formation. In production it stays open, with less than 3 psi pressure drop at 2,000 BPD. It fits new or existing completions, above or below the packer. Talk to our engineering team about your next workover:
