Wellvene SwellStack

Developed in collaboration with TAQA, the Wellvene SwellStack is a WRSSSV proven to seal in gas up to 10,000psi within damaged seal bores having a wire tracked groove up to 1.65mm in depth.

Building on TAQA’s patented technology for swellable O-rings, the SwellStack ensures production can be reinstated to wells that are closed in due to an inability to obtain a seal during the installation of a wireline insert afety valve.

DESCRIPTION

• The SwellStack design incorporates the knowledge gained from standard TAQA swellable compounds, which have been used in over 65,000 successful installations worldwide.
• Cost-effective solution to extend the life of the existing WRSSSV
• Simplified deployment option
• Maximum reliability for severely damaged and corroded sealbores
• Maintained well integrity
• Removes the requirement for WRSSSV straddles and potential workovers
