Wireline Retrievable DHSV SwellStack
Downhole safety valves become corroded or damaged due to wireline activity. Standard chevron stacks in insert valves are unable to effectively seal in this damage and result in a leak path for hydrocarbons to migrate up the control line.
SwellStack, a swellable sealing solution with multiple chevron seals, is installed in place of an existing chevron stack.
This patented technology regains well integrity, effectively providing a seal of 10,000psi in liquid and gas.
