Double / Single valve jet swirl is designed for running and cementing linerassemblies with the contingent ability to be set on bottom in the event theliner does not hang. Specifically, there are features not present in moreconventional primary cementing shoes.Internal components are constructed of cement, thermo-plastic, andrubber, compatible for fast and easy PDC drillable. The float assembliesare tested and rated to API recommended practice 10F. The uniquedesign of the molded rubber seal prevents impingement and erosion of theseals by the circulating fluids, ensuring a positive seal at conclusion of theliner installation.The body of the jet swirl is manufactured of material matching the grade ofthe liner casing, which provides performance equal to or greater than thatof the liner casing.

Double / Single valve bottom set jet swirl shoe is designed for running and cementing liner assemblies with the contingent ability to be set on bottom in the event the liner does not hang. Specifically, there are features not present in more conventional primary cementing shoes. These features include:

Spade nose with anti-rotation fins which allow the liner to remain stationary while the work string is rotated to release from the liner assembly. Since and down circulation ports. In many cases, the liner is set close to the bottom of the hole and may encounter cuttings and other well debris. The side and down ports aid in the flow of cement in these debris filled applications. This is of particular importance when the liner is set on bottom. Internal components are constructed of cement, thermo-plastic, and rubber, compatible for fast and easy PDC drillable. The float assembliesare tested and rated to API recommended practice 10F. The unique design of the molded rubber seal prevents impingement and erosion of the seals by the circulating fluids, ensuring a positive seal at conclusion of the liner installation.The body of the jet swirl is manufactured of material matching the grade of the liner casing, which provides performance equal to or greater than that of the liner casing.

Stab-In cementing is an improved method for cementing large diameter casing. Conventional methods require excessive amounts of cement to ensure cement circulation to surface because of open hole volume, losses to the formation, or mud displacement efficiency that cannot be determined with sufficient accuracy. In addition, large plugs must be used to separate the cement from the mud and have to be drilled out, along with any cement in the casing. With stab-in cementing, the Drill Pipe is stabbed directly into the Float Shoe or Collar and cement is pumped through the drill pipe until returns reach surface. Cement is then displaced to the bottom of the Drill Pipe — a wiper dart can be used. The drill pipe is then picked up, circulated, and pulled out of the hole.

Use : The WELLCARE Stab In Float Equipments are used for cementing large diameter casings lowered on drill pipe. The string presents special cementing consideration due to high displacement volume of large diameter casing. Problem with high displacement are overcome by using Stab in Cementing Equipment to allow cementing through drill pipe.

Features :

• Small diameter inner string off drill pipe is used to displace cement which minimizes displacement volume behind cement and there by reduces contamination and save time.
• Drill out of cement inside large casing is minimized by controlling cement top with displacement fluid in drill pipe and Poppet valve in Stab in Shoe.

Advantages :

• Improve displacement accuracy — cement mixing and pumping continues until cement returns reach surface.
• Get better cement quality — the reduced cement/mud interface area and high velocity of flow in the Drill Pipe minimize cement contamination while the short pumping time eliminates the need for cement retarders.
• Reduce cement volume — conventional displacement requires calculation of excess cement factor, whereas with stab-in methods excess cement need be no greater than the volume of the drill pipe.
• No large plugs are needed.
• Reduce net rig time — circulating, pumping, and drill-out times are minimized.
• Protect casing — cementing pressures are confined to the drill pipe as in a squeeze job.

This Shoe is used to provide turbulent flow at the shoe and where obstructions are expected while running in, the Down-Jet Swirl ports allow operator to “wash” casing down.

Cement/Poppet-type Float equipment offers dependable performance for all classes oil and gas wells. The valves prevent cement backflow, provide casing buoyancy during run in, and act as internal BOPs during the process of running and cementing the casing. Float equipment is manufactured to match customer casing specification. All ball type cement float collars are PDC drillable. Butt-Weld Casing Collar O.D. matches with the casing O.D. and upper end is only beveled, not recessed for directly welding to the Casing pipe.

Duplex Shoes and Collars sizes 6 5/8” to 30” are furnished with heavy

duty duplex connection. These heavy duty connections have 4” OD left

hand threads and 3¼” seal bores and are capable of carrying 100, 000 lbs.

with a minimum safety factor 2. Special accessory products are available

for use with this large Duplex Equipment. The Tubing Seal Nipple has

field proven Chevron Seals for positive sealing of the nipple in the seal

bore. It features an expandable left hand latch mechanism, allow the

nipple to be “stabbed” into the duplex connection, and when up-strain is

applied the latch is expanded to provide full engagement in 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” OD left hand threads are also available for use with Large Duplex

Equipment

This Cement Guide Shoe may be used in combination with any type of collar. It efficiently guides casing past sidewall irregularities.

Differential Fill-up Float Equipment allows 90 per cent casing fill-up during run-in, reducing surge pressures caused by the piston effect of running casing in restricted IDs. Use of Differential Collar with Shoe provides additional buoyancy by allowing only 81 per cent casing fill-up further enhancing draw works efficiency. Circulation can be established at any time while running in. Dropping a ball converts the Differential Valve to a regular Back-Pressure Valve. When Collar and Shoe are run together, dropping one ball converts both units.

The Auto Fill Cement Float Shoe permits the casing to fill automatically while being run into the hole. The valve is in the open position while running in allowing maximum filling of the casing as it is lowered into the well bore. This is especially effective on liner jobs and sensitive whole conditions. 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. 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 are PDC drillable.
