Top Drive Casing Running Tools

Tools that engage the inside diameter of the casing with an expandable internal slip/spear assembly to transmit hoist load and torque. Common for larger-diameter casing where internal engagement provides a clean external profile.

Tools that grip the outside diameter of the casing with an external slip or grapple, useful where internal access is restricted or where a float/landing collar limits internal gripping depth.

Configurations sized to handle one joint at a time or pre-assembled stands; stand-running variants increase running speed on deep strings by reducing the number of make-up cycles at the rig floor.

Top-drive-mounted systems combining gripping, torque transmission, and a fill-up/circulation tool in one assembly, allowing rotation and circulation through the casing as it is run.

Sub-assemblies with a sealing mandrel and cup or packoff that establish a pressure seal to the casing bore so the string can be filled and mud circulated during running and cementing.

TDCRT configurations adapted to run and rotate liner strings on drill pipe, integrating with the liner hanger setting sequence and allowing circulation and rotation during cementing of the liner.

Interchangeable load-bearing gripping elements sized by casing OD and weight, selected to match pipe diameter, wall thickness, and required torque and hook-load ratings.

Hydraulic actuation, torque-turn make-up monitoring, and load-sensing instrumentation that verify connection make-up and grip engagement remotely from the driller's console, supporting hands-free floor operations.
