Single valve float shoe with free-rotating eccentric aluminum guide nose Type 255 and modifications

Designed for equipping bottom of the casing string to direct it in the wellbore and protect from damages during oil and gas well casing. It provides optimal conditions for running a pipe string into the well, ensuring target depth reach. It prevents reverse flow of the cement slurry from the annulus into the pipe string during cementing.

Available sizes: 101.60 mm (4'') to 339.72 mm (13 3/ 8'').

Thread connections: OTTM, OTTG, BTC, TMK UP™, VAM TOP®, NEW VAM, VAsuperior®, VAGT®, JFEBear®.

Application:

  • Vertical, directional, horizontal and ERD wells.

Features:

  • Reliable and time-proven Real Seal II™ float valve, incorporated in the shoe, withstands high back pressure and continuous flushing with high sand content fluid;
  • Auto fill-up mechanism provides automatic casing string fill-up with fluid while running into the well;
  • Safe Lock™ non-rotation mechanism prevents the cementing plug from rotating in the process of drilling out;
  • Duralumin guide nose withstands high axial and radial loads;
  • Guide nose rotates to direct the shoe while running in the well, allowing it to overcome obstacles and providing continuous running of casing or liner to the target depth;
  • Eccentric form of the guide nose facilitates the process of casing running in the well;
  • Design of the shoe allows its use in wellbore of any curvature;
  • Design of the shoe is adjusted for drilling out with PDC bit.
