Auto Fill Cementing Float Collar

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
