Float Equipment Built for the Systems Above It
When you run a Liberty liner hanger, you need float equipment that meets the same standard. Endeavor was engineered alongside Liberty — matched pressure ratings, matched temperature class, matched manufacturing standard. One source, one standard, surface to TD.
All-Metal Construction
No elastomers. No rubber elements to degrade at temperature. Endeavor uses all-metal sealing technology — engineered for the 400°F HPHT conditions where conventional float equipment fails.
Shatter Glass Technology
Endeavor’s flotation collar uses precision Shatter Glass Technology for clean, pressure-activated opening. Predictable timing. Zero debris. No surprises at 12,000 feet.
Matched to Liberty
Designed to work with Liberty liner hangers — same pressure class, same temperature rating, same manufacturing standard. One source of accountability from hanger to shoe.
HPHT 15K Flotation Equipment
All-metal float equipment rated to 15,000 PSI and 400°F — the matched shoe, collar, and wet shoe for the production liner interval where elastomer-based tools fail.
Endeavor Float Shoe
Guides the liner to bottom and prevents backflow during cement displacement. An all-metal check valve with an eccentric cast-iron nose, built for HPHT service where elastomers fail.

Tomahawk™ Wet Shoe
Delivers reliable toe initiation while simplifying operations on location. A fully engineered toe-initiation mechanism consolidates the shoe track, reduces connections, and provides more consistent injection than complex toe-sleeve systems — for both long string and liner applications.

Barrier Subs
Run an atmospheric flotation barrier in the horizontal to cut friction and drag — then clear it to a fullbore casing ID with no debris left behind.
Glass Disk Casing Flotation Sub
Traps an atmospheric chamber in the horizontal section to cut friction and drag, concentrating hook load in the vertical — giving the operator a better chance to reach TD. A pressure-activated glass disk shatters into fragments for a fullbore casing ID, with no junk basket required.

Plugs
Latch-in cementing plugs that cleanly separate cement from displacement fluid and confirm complete placement with a positive bump at surface.
Endeavor Wiper Plug
Latch-in dual-fin top plug separating cement from displacement fluid. An aluminum latch body with HNBR 75D wiper fins delivers a clean, positive bump confirming complete cement placement at surface.
