DURA Drill Float
The Double Upper Reserve Activated (DURATM) Float is a contingency float option that provides operators with a dormant secondary dual float that can be activated on demand.
Applications include protection post stuck pipe severance (HyPR™), protection should a leak path develop in the BHA, or if the primary float should fail.
Based on the proven Self-Filling FloatTM, the dart activated large bore float is fitted with a dual flapper arrangement. This acts as a back-up to the primary float in the string and provides unparalleled sealing technology and redundancy when activated.
The float is placed at the top of the BHA and can be rapidly activated by pumping a dart from surface.
