DURA Drill Float™

The Double Upper Reserve Activating (DURA™) Float provides operators with superior well control on a number of contingency applications.

Running the DURA, operators benefit from a dormant large bore float situated above the BHA which can be rapidly activated by pumping a dart from surface.


Superior contingency well control

Providing operators with superior well control, the DURA de-risks contingency operations, including:

  • Stuck pipe severance 
  • Drill String failure in BHA 
  • BHA leak paths 
  • Primary float failure 

 Based on the proven Self Filling Float™ technology, the dart activated DURA float is fitted with a dual flapper arrangement - providing unparalleled sealing technology and redundancy.

The Smart Choice

  • Superior double float protection providing the ultimate contingency
  • Allows Self-Filling and through bore until activated
  • Activated by a fishable Churchill smart dart
  • Large bore allows most activators to travel through safely while in dormant mode
  • Continue drilling even after the tool is activated
  • 10,000 psi working pressure
