Wide Ranges of Sizes and Configurations of Cement Float Shoe & collar

Double Valve Cement Float Shoe & Collar

FSC-02-DV

Double valve type of cement float shoe and collar is the advanced configuration of single valve type. It acts as an extra back pressure calve sealing against pressure from below when floating in a linear or casing.

Performance Features

• Fast Drill-out
• Valve parts will not damage PDC Bits.
• Double valve acts as an extra back pressure valve.
• All materials are PDC Drillable.

Options

• Available from sizes 4-1/2" till 36"+ any sizes configurations.
• Special sizes and configurations are available as request.
• Available with shoes with cement nose, aluminum nose or bladed nose.

Down Jet / Up Jet Cement Float Shoe

FSC-03-DUJ

Down jet or up jet cement float shoe make it easy to circulate through down-jets or center of the shoe while running in the hole. This provides a means of washing casing/liner to seat if required. Once converted, has the ability for the cement to be pumped through up-jets for optimum cement placement. Parts force circulation flow in a downward jetting action.

The down-jets/up-jets cement float shoe is also available with double valve for extra back pressure, valve sealing against pressure from below when floating in a liner or casing.

Performance features

• Circulate through down-jets or center of the shoe.
• Fast drill-out
• All materials are PDC drillable.
• Cost effective

Options

• Available in sizes 9-5/8" to 30" configurations.
• Also available with double valve

Stab-In Cement Float Shoe & Collar

FSC-04-SI

Stab-in cement float shoe and collar is widely used for cementing large diameter casing, lowered on the drill pipe. The string presents special cementing consideration due to high displacement volume of large diameter casing.

The drill pipe is tabbed directly into the float shoe or collar and cement is pumped through the drill pipe until it returns to reach the surface. Then the cement is displaced to the bottom of the drill pipe, a wiper dart can be use. The drill pipe is then picked up, circulated and pulled out of the hole.

Performance features

• Improves displacement accuracy
• Get better cementing quality
• Reduces cement volume
• Reduce rig time
• Protect casing.

Options

• Available from sizes 9-5/8" to 30"
• Available with double valve

Duplex Cement Float Shoe & Collar

FSC-05-DC

Duplex cement float shoe and collar are furnished with heavy duty duplex connection. These heavy duty connections have 4" O.D. left-hand threads, 3-1/4" to 1" bores and are capable of carrying 100,000 lbs with a minimum safety factor of 2. special accessories are available for using with large duplex equipment. The tubing seal nipple has field-proven Chevron seals for positive sealing of the nipple in the seal bore.

Duplex cement float shoe and collar has an expandable left-hand latch mechanism which allows the nipple to be "stabbed" into the duplex connection and when up-strain is applied the latch is expanded to provide full engagement in the duplex assembly. The nipple is released by rotating to the right, unscrewing the latch mechanism of the duplex connection. Left-hand square thread subs with 4" O.D., left-hand threads are also available for use with large duplex equipment.

Performance features

• Is supplied with plunger valve in most of the application
• Material is seamless casing grade steel.
• PDC drillable.
• Reduce rig time.
• Protect casing.

Options

• Available from sizes 9-5/8" to 30".
• Also available with double valve.

Butt Weld Cement Float Shoe and Collar

FSC-06-BW

Butt weld cement float shoe and collars are designed with non-thread structure, which have beveled upper end, which is convenient for directly welding onto the casing pipe. The O.D. of butt weld casing collar matches with the casing O.D.

Performance features

• Same performance with other types of cement collar and shoes.
• Upper end is beveled and not recessed for directly welding to the casing pipe.

Options

Available from sizes 5-1/2" to 20" sizes configurations.

Auto-Fill Cement Float Shoe and Collar

FSC-07-AF

Auto Fill Cement Float Shoe & Collar permits the casing to fill automatically while being run in the hole. The valve is always in the open position 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. 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 shoe is activated by the same ball. From this point on, like differential fill-up shoe, this model Auto Fill Cement Float Shoe acts as conventional floating equipment. All Auto Fill Cement Float Shoes & Collar are PDC drillable. This is especially effective on liner job and sensitive hole conditions.

Performance features

• Auto-fill-up and pump-out sleeves are available to convert into an automatic fill-up unit.
• Withstand various differential pressures.
• Is installed in short 8 round API casing couplings in sallow well applications.

Options

• Available in sizes 9-5/8" to 30".
• Non-rotating auto fill float collar is also available.
• Available with double valve.

Non-Rotational Cement Float Collar

FSC-08-NC

Non-rotational cement float Collar is Non-Rotational type pressure and cementing plug activated. The latch down type anti-rotational feature of the plug which is compatible with the Float Collar eliminates rotation during drilling. The Cement Float Collar is also available with double valve for extra back pressure valve sealing against pressure from below when floating in a liner or casing.

Performance features

• Match with non-rotational cementing plugs.
• Eliminates rotation during drilling.
• Operator-controlled buoyancy-regulated by filling casing at surface.
• Manufactured to withstand various differential pressures.
• Float equipment's are PDC drillable

Options

• Available in sizes 9-5/8" to 30".
• Withstand various differential pressure.
