Auto-Fill Float Collar Forging Processing Type Customized ODM Service
Float shoes contain a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing.
The Auto Fill Cement Float Shoe allows the casing to fill automatically while run into the hole.
This is especially effective on liner jobs and sensitive whole conditions.
The valve is in the open position while running in allowing maximum filling of the casing as it is lowered into the well bore.
The circulation may be established at any time during or after casing is run.
From this point on like Differential Fill-up Shoe, this model Auto Fill Cement Float Shoe acts as conventional Floating Equipment.
The flapper type back pressure valve does not become operative until the drop ball is dropped or pumped down.
All Auto fill Cement Float Shoes are PDC drillable.
