command enhanced torque connection

COMMAND ENHANCED TORQUE CONNECTION
The CET™ connection has
many advantages over API and
the competition when used for
drilling deep wells, extended
reach wells, horizontal wells,
and slim hole wells.
Least turns to make-up of any
premium connection
170%-200% of the torsional
strength API connections
Available on drill pipe and heavy-weight
drill pipe in sizes from CET™26 to CET™69
Due to the higher make-up torque of the
CET™, it is ideal for use in the extended
reach laterals found in today’s shale plays
Increased Torsional Yield Strength
The CET™ has increased torsional yield strength due to the addition of a secondary shoulder.
The secondary shoulder is a mechanical stop that reduces internal stresses in the pin and box
of the connection allowing the connection to handle more torque. As an example, a 5 1/4”
OD and 2 9/16” ID NC40 connection make-up torque would be of 16,600 ft-lbs and a CET™39
connection with 4 7/8” OD and 2 11/16” ID dimensions would have a make-up torque of
22,200 ft-lbs.
Improved Hydraulic Efficiencies
The CET™ connection has a smooth ID through the connection. The connection can be made
with smaller OD’s and larger ID’s than a standard API connection and have higher torque
capacities. The larger and smoother ID improves the hydraulic efficiency of the tool joints.
This also helps prevent cement and other items from becoming trapped in the tool joint.
When drilling smaller OD holes, CET™’s smaller OD tool joints improves hydraulic efficiency
and allows the pipe to be fished if necessary.
Lower Maintenance and Running Costs
The CET™ costs less to maintain than the competitors due to the simple maintenance facility
licensing structure that includes no royalties. Command Energy Services recommends the
use of a stabbing guide when using the CET™ connection. Doing so will reduce the amount
of repairs required to less than 1% per inspection, CET™ saves time by requiring only 5 turns
to make-up.
Increased Wear Resistance
The life of your drill pipe is extended by being able to wear to a smaller OD than API
connections while maintaining a torsional capacity greater than 80% of the drill pipe tube.
The minimum OD varies with grade and weight of the drill pipe.
