API Single Valve Float Shoes Concentric Nose PDC Drillable Slip On Connection
Features:
The Auto Fill Cement Float shoe & Collar permits the casing to fill automatically while being run into the hole.
The valve is always in the open side position allowing maximum filling of the casing as it is lowered into the well bore.
This is especially suitable for liner jobs and sensitive hole conditions.
The circulation may be established at any times during casing running.
The flapper type back pressure valve does not be operated until the drop ball is dropped or pumped down.
Like Differential Fill-up Equipment type, the Collar is activated by the same ball.
From this point, like Differential Fill-up Collar, this Auto Fill Cement Float Collar acts as conventional Floating Equipment.
All Auto Fill Cement Float Collars are PDC drillable
