Absolute’s wide range of adjustable Extreme Circulation Shoes provides a versatile circulating, drill-down or drill-in assembly to accommodate any type of fill or obstruction.
Excessive set-down force can create a bad situation for the conventional float shoe. Over 1000’s of liner installations, Absolute has gained experience in challenging situations that have lead to innovations and improvement of even a bullnose.
- Circulate-past
- Drill-down
- Drill-in
Absolute Extreme Circulation Shoes in any configuration operate by way of an adjustable spring tensioned, plunger type valve that opens at a desired circulation pressure from 0 to 200lbs. The assembly’s conical positive action valve prevents any sand from plugging the shoes no matter how dense the fill or how high the set-down weight.
Cone
A Conventional style, adjustable circulating cone that is designed to enhance fluid velocities within a chamber created by contact with the fill, provides maximum circulation in an isolated area that penetrates even the toughest obstructions.
Cutting
Turn any liner into place. For maximum penetration into compacted obstructions, sharp star fins provide an aggressive cutting surface
Cutting Star-Fin
The cutting bullnose provides a moderate cutting surface combined with specially designed channels that transfer high velocity fluid to the drill-down surface.
Bullnose
A typical push-by shoe that provides the advantages of adjustment and plug prevention by way of the assembly’s internal valve.
Bullnose Star-Fin
A dual purpose shoe, push by fill plus the option to speed up conveyance using the tough star fins to drill by hard obstructions.
