BiSN

Engineered Sealing Solutions:
Seal Safer, Protect Forever.

BiSN’s innovative bismuth-based technologies – wel-lokTM extend the life of your well and permanently solve downhole flow issues so you can maximize production from all your assets.

Sealing methods that use non-permanent materials alone such as cement,elastomers and resins cannot solve well issues like water production and gas migration reliably for the long term.

BiSN’s unique field-proven Performance Barrier Technologies allow operators to solve unwanted downhole flow issues once and for all – sealing across the life of the well with confidence to assure uptime, improve production, extend well life and ultimately abandon safely, and forever.
