>>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.
