ROTZ-1 & ROTZ-2 Lock Mandrel Sub-Assembly
Rebco ROTZ-1 & ROTZ-2 is a Bottom No-Go, Non Flowing Lock. Lock Mandrel Sub-Assembly has Locks (Dogs) facing up which prevent upward movement, but depends on accessory No-Go shoulder to prevent the Lock Mandrel from downward movement. The Lock Mandrel can be used in a Bottom No-Go type Nipple only.
Product Code: 10
Applications
Bottom No-Go, non-flowing lock applications where depth control is referenced from below by the accessory's No-Go shoulder
Completions using Bottom No-Go type nipples only; the ROTZ cannot be used in a Top No-Go nipple
Nominal tubing sizes from 1.660" through 4.50", with seal bore coverage from 1.18" to 3.81"
Key Benefits
The Bottom No-Go design complements the ROTW Top No-Go offering, giving operators a choice of No-Go orientation to suit the nipple type already installed in the completion string.
Upward-facing Dogs provide secure resistance against upward displacement once the lock is set.
The No-Go function is built into the accessory rather than the lock body, allowing the same sub-assembly to be paired with different accessories while maintaining correct depth positioning.
Available in a variety of materials for downhole service conditions.
NOTE: Required Running and Pulling Tools with appropriate Probes are shown in ENGINEERING DATA for Type of Accessories attached to the Lock Mandrel Sub-Assembly.
Rebco ROTZ-1 & ROTZ-2 Lock Mandrel Sub-Assemblies are available in variety of Materials, suitable for down-hole conditions.
