Non Rotating Float Collar ( Single/Double Valve )

The Non-rotating Float Collar is attached to the end of the casing string and they are used to stop slurry from flowing back. Material inside is easily drillable; the anti-rotation mechanism on the top improves drill-out performance. The valve consists of rubber and polymer materials with high tensile strength. Single or double valves are available.

These are available in 2 7/8" to 30 "sizes + any special size on customer demand

This design contains an internal taper on the bottom to ensure trouble-free entry of drilling tools back into the casing string after drill out and during drilling operation. All Guide Shoes and internal components are fully PDC drillable.

It reduces problems associated with hitting rock ledges therefore reducing chances of sidewell cave-in. These are available with Butt-welded, slip on and threaded end and from sizes 2 7/8” to 30” sizes + any special size on customer demand

Reamer Shoe ( Single/Double Valve )

COS's Reamer Shoe is designed with blade cutting structure and diamond shaped faces which ensures safe passage of casing and liners thus facilitating rotating and reciprocating applications. It effectively negotiates around ledges, swelling shale, mud cake build-up on porous formations, or sand bridges occurring in the wellbore.

The aluminium eccentric guide nose climbs ledges and negotiates obstructions while the cutting structure reams out tight spots or obstruction in the wellbore. Compatible with all casing and liner hanger assemblies, our Reamer Shoe provides highly effective protection- against unexpected or anticipated casing and liner running problems, the high strength profiled alloy nose will anchor even in uncured cement to facilitate ease of drill out. The aluminium eccentric nose is easily drilled with both PDC and Rock bits. The chip breaker holes in the nose assembly are designed to create small aluminium chips to avoid “bird nesting” on the bit.

These are available in 4 1/2" to 30 "sizes + any special size on customer demand.
