Casing Drive System

A revolutionary CDS allows casing rotation & circulation simultaneously and solves problems that are beyond conventional technology solutions.

 

Features

CDS connects to the top drive which power to rotate casing

CDS Hydraulic Power Unit ( HPU ) provides power for casing anchoring

Set slips on casing and lower top drive enable CDS to grapple enter into casing box and anchor it. The casings can be lifted, lowered, rotated, and circulated by operating the top drive

Torque monitoring system ensures the safety of casing connection

Operating pressure of 5000psi with super seal between casing and CDS to eliminate mud leaks from casing during circulation

 

Benefits

Casing makes up easily as CDS connected to TDS, eliminating using tools like tong, power, and elevator

Well control ensured and mud fill-up time reduced as casing remains connected with top drive during its running

Casing rotates and mud circulates simultaneously for wellbore cleaning

Manual stabilizing and tongs abolished safeguard the safety of the operating personnel

Co-work with reaming shoes to pass through under/over-gauged hole sections by rotating and circulating casing

Run with drilling shoes to pass through collapsing sections and cement them afterwards
