CET™

Longer lateral sections push the torque limits of standard API connections. The CET™ connection design provides increased torque with the addition of an optimized secondary torque shoulder. The resulting balanced connection has reduced internal stress at greater torque loads than any other high torque drill pipe connection. For example, CET43 has over 31,700 ft-Ibs of torque with a 3″ ID, and 100,000 lbs of elevator capacity over the standard 4-1/2″ Slimhole assembly that has a 5 3/8″ OD connection.

5-1/2″ drill pipe with the CET54 connection has reduced drilling time through increased ROP, reduced pressure drop, increased torque, increased weight on bit (WOB), and higher flow rates. Additionally, on 5″ drill pipe the CET50 connection offers all of the features above without requiring racking board modifications while still using the rig supplied handling tools.
On 4-1/2″ drill pipe the CET43 connection provides a faster spud to TD option that eliminates the use of traditional 5″ NC50 and 4″ high torque drill string assemblies by reducing inefficiencies associated with laydown time.
These advances in drill string design further correlate to the improvements on 2-7/8″ drill pipe, where the CET24 connection achieves faster and deeper drill-outs and workovers on extended reach laterals.

The CET™ design utilizes an API thread-form that allows for deeper stabbing, maximizes landing threads and reduces costly repairs while minimizing trip time. When repairs are required, the design minimizes tool joint loss, further extending the life of the string. The simplified licensing structure of the CET™ connection reduces cost by excluding royalties, does not require proprietary machine inserts and leverages over 50 licensee shops in all major operating regions around the world.
