Auto Fill Float Shoe and Collar

The COS Auto Fill Float Shoe and Collar are engineered to simplify casing running operations by automatically filling the casing with wellbore fluid as it descends. This smart self-filling mechanism reduces running time, minimizes surface handling, and lowers hydrostatic pressure on weak formations. Once circulation or cementing pressure is applied, the valve automatically seals, ensuring secure and reliable performance in even the most challenging well conditions.

Constructed from high-strength casing-grade steel and durable polymer components, the Auto Fill Float Shoe and Collar deliver long-lasting reliability while remaining fully PDC drillable for quick and efficient drill-out.
