Float Collar, Cement / Orifice / Stab-in // Size 2 7/8"-30" Material Any Drillability Yes Category IA,IIB AND IIIC Type Cement with duplex valve

Completion Oil Tools® float collar allow operator to maintain a constant fluid height inside the casing of a well as fluid is allowed to enter through the bottom of the casing.

The system maintains a constant differential pressure between the inside and outside of the casing at the floats to ensure constant fluid height within the casing. A spring-loaded valve in the fill-up unit regulates filling.

Completion Oil Tools® orifice float collar for cemented tieback applications, and the PBR seal nipple is combined with a stage collar or ported put and an orifice float collar.

The orifice float collar is designed with small diameter drilled holes through the float valve to allow fluid bypass and preventing hydraulic lock as the seal nipple stabs into the pbr after cement is in place.

A polished mill is run before to clean out PBR.

Cementing large diameter casing (up to 30”) used for conductor, surface an intermediate string presents special cementing consideration due to high displacement volume of large diameter casing.

Problems with high displacement are overcome by using stab in float collar of COT® to allow cementing through drill pipe.
