Same drill out features as stage collar. Provides significant cost savings. Type T Tag-in float collar Typically used for large diameter surface casing applications. Plugs lock apii upward movement to prevent them from being unseated while being drilled out. After landing on the bottom sleeve, it pushes both DFC sleeves ahead of the cement to the float collar below. Type Integral Casing Packers. Prevents unwanted water intrusion. Same PVTS valve internals.
Typically used when PDC bits will be employed for drill out. Can be made from steel or aluminum. Seals providing internal and external integrity are housed in the tool body and rl stationary throughout operation of the tool.
Typically used on intermediate and production casings, at times on surface casings. Single entry port for installing shear pins. Appi for all casing sizes. Available for two or three stage cementing applications. Selective placement of cement across widely separated zones of interest. Bottom cementing plug ruptures, and cement is pumped through and out of the float equipment. Drop ball-seat size is adjustable from 1. Type Down Jet Float Shoes.
External rubber swells and seals where cement performance has been poor.
Installation could remove the need for cement squeeze. Run in close tolerance applications mainly on liners.
Reduced displacement volumes of drill pipe versus casing. Davis Flotation Collar Sleeves and plug land on float collar Bottom cementing plug and sleeves land and seal on the float collar. Sleeves lock against rotation for easy drill out.
Closing sleeve held closed with internal lock ring. Manufacturing done in Ruma Transport, sand blasting, coating, compounding, rolling and vulcanising.

End collar hinges folded inward to reduce risk of collar stretch. Type Packer Stage Cementing Collar. Aoi conversion pressure from psi to psi. Casing Fill and Circulate Tools. Cement Baskets Simple, economical annular pack-off.
Type Float Shoes Rounded design of concrete nose assists in guiding string to bottom. Tapered nose for leading edge of casing string allows for effective running through tight spots, irregular well bores, previous casings that have been damaged etc Center hole in nose is designed to prevent a;i balls from potentially sealing off thereby reducing flow area. Suitable for most applications up to 35 degrees deviation. Also available in a float collar configuration.
Allows for lead cement to be apo until surface returns are seen, then tail. Ream Master Float Shoes.

Controls wellbore migration of gas and fluid. Configuration with receiver for adapter incorporated into shoe. Cast Aluminum nose material standard, easily drilled out due to numerous break points jets and shorter design.
Can remove the need for a cement squeeze. Solid Body Rigid Centralizers Centralization through positive or rigid centralization. Keeps hydrostatic head of second stage cement off of first stage cement. Casing above the DFC is filled with drilling fluid as casing run continues to desired depth.
Casing fills automatically while running. Keeps hydrostatic head of second stage cement off of pressure sensitive zones below. Eccentric Nose 110f Shoe An aid to run casing in adverse conditions with off-center nose piece.
Reliable double-valve flapper design with large inlet.
