Auto Back Flow Preventer Valve

Auto Back Flow Preventer is a spring loaded check valve designed for use in salt water disposal wells, water floods, and supercritical CO2 injection. Deployed downhole on the tubing string below the annular packer, the Auto Back Flow Preventer keeps previously disposed of fluid from entering the tubing string when the injection is ceased. This offers isolation downhole and prevents high pressure downhole fluid from returning to the surface.


This is a cost-effective solution that has been deployed countless times across numerous different basins. It is strongly recommended to run a knockout drain above the ABFP to prevent from pulling the tubing string wet.
