Features:
The Auto Fill Cement Float Collar permits the casing to fill automatically while being run into the hole.
The valve is always in the open position allowing maximum filling of the casing as it is lowered into the well bore.
This is especially effective on liner jobs and sensitive hole conditions.
The circulation may be established at any time during or after casing is run.
The flapper type back pressure valve does not become operative until the drop ball is dropped or pumped down.
Like Differential Fill-up Equipment, the Collar is activated by the same ball.
From this point on, 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
