Well Construction · Liner Accessories

Seal it, float it, land it, tie it back — one string, no surprises.

The supporting string — seals at the top, floats and collars at the bottom, and the tools that run and release it — designed and manufactured together as one integrated system.

The benefit to the operator is simple: no stitching together mismatched imports, no interface guesswork, one package that runs, seals and lands predictably. Flow-assisted sealing controls annular gas migration after cementing; drillable floats and collars mean fast, trouble-free drill-out; and running tools release cleanly even on long, heavy, extended-reach strings — so nothing is left downhole and nothing needs a second trip.
