“No Squeeze” Tornado Up-Jet Centralized Float Shoes And Collars

Design

The new patented solid blade Stand-Off Float Shoe and Float Collar have been designed and developed to completely eliminate secondary cement squeezing of the casing shoe seats. The solid straight blades of the float equipment will give the casing a bob sled ride into the wellbore: no turning, no dragging, no scraping, and no clogging between blades. The unique tornado design of the jets between each set of blades in the float shoe plus a downward jet will assure complete cement coverage around the shoe, even on the narrow side. Forcing cement up the narrow side of the pipe is the solution to getting 100% cement coverage.

Drillable Materials

A Superior back-pressure valve assembly is totally made of recommended PDC bit drillable phenolic material bonded to the U-type grooves in the steel housing with special high-strength concrete.

Tests

ROTCO Stand-Off Float Equipment design and material have successfully endured the maximum API RP1OF 24-hour flow durability test and 5000 psi differential pressure tests.

Usage

The ROTCO Stand-Off Float Equipment is recommended on all casing shoe joints where rock solid shoe seats are essential. That is, these new deep water wells where rig time is very expensive, horizontal wells with open hole completions, explatory wells with heavy mud programs, and close tolerance drilling liners where casing centralization and successful cementing has been a problem.

Success

This unique Float Shoe made the “No Squeeze System™” possible and our phrase, “If the cement has set up, there will be no reason to squeeze.”

Less Cost

With the usage of the Centralized Float equipment and the unique up-jet system between blades, less expensive mud/cement spacer can be used and still get good cement around the shoe joints.
