Easy to drill out with PDC or roller-cone rock bits
The Super Seal II standard float shoe attaches to the lower end of the casing string. This float shoe includes the Super Seal II backpressure valve assembly, which prevents cement in the annulus from re-entering the casing ID.
The plastic valve and stem materials are surrounded by drillable concrete, making the equipment easy to drill out with PDC or roller-cone rock bits. The high-strength, durable rounded nose safely guides the casing to the bottom of the hole.
This equipment is available in all tubing and casing sizes with API 8-rd and buttress threads. The standard casing grade is K-55 material. Customers can request any casing grade and premium thread by special order.
The Super Seal II system is now adding the universal blank
RPT reamer shoe (Figure 1), designed to cut a variety of casing
threads within a given casing size and weight range. The Super Seal
II float valve has been used in cementing operations in every part
of the globe where reliability and dependability are required.
