DRILL PIPE SWIVEL

SMART, SIMPLE & LOCKABLE SWIVEL TECHNOLOGY

#RedefineTRS™

LOCKABLE SWIVEL – SELECTIVE ROTATION DEVICE

The Deep Casing Tools Drill Pipe Swivel allows drill pipe above the liner hanger and packer tools to be rotated independently below it. The ability to rotate the drill pipe above the liner in an ERD well reduces drag, redistributes friction and mitigates helical buckling of the work-string.

The result of rotating the drill string above the liner is increased weight available at the tool to push the liner string, often sand control screens, into the well to TD.

FEATURES

Heading #3
Heading #3
Increases available weight to push liners to TD in ERD wells
Eliminates or reduces need for heavy weight drill pipe or drill collars
Single tool reduces the HSE risk compared to multiple roller bearing subs
Enables mechanical release of setting tools when required
Protects items below from potential harmful torque
100% simple mechanical action to lock the tool
Immediate locking when required
Reduces HSE risk, saves time
No need for ball or dart to lock tool, time saved
No need for pressure to flow to lock
