• Making Up Connections

    Stabbing-in Connections 

    Ensure correct alignment prior to stabbing. Automatic stabbing systems (top-drive, iron roughneck, pipe-racking systems) must be set to ensure alignment. Using a stabbing guide:

    • Ensures correct angle of stabbing pin into box
    • Reduces chance of shoulder damage (Especially important for double shoulder connections)
    • Increases safety (removing pinch point)
    • Saves rig time (no need to stabilize string before stabbing)


    Spinning In

    Maintain proper alignment when spinning-up connections. Misalignment can damage threads. Use reduced speed for initial turns until sufficient engagement is achieved. Increase speed thereafter. Reverse rotation if cross threads for premium connections (except HT™ and GPDS™). Connection shall shoulder at end of spinning. No contact indicates an issue. Mill varnish may need to be removed if it fills up spinners/rollers and creates sliding.

    Gripping for Make-up 

    Place the tongs as low as possible on the box respecting requirements for minimum distance from sealing shoulder. Tong can be set very low on the pin tong area as long as they do not interfere with the box tool joint. One torquing grip is enough to make up the connection. The need for multiple grips indicates an issue.



    Connection break-in on the rig floor 

    Before the joints are put in service, connection must be broken in; either in a factory make-and-break or on the rig floor. For 3-cycle rig floor break in follow the below steps:

    1. Make up joints as slow as possible, to 100% of make-up torque (MUT). Break them out. If the break-out torque is less than the MUT, the connections do not have to be separated.
    2. Make up the connections again to the same torque. Break them out. Separate pin and box. Repeat.
    3. Reapply thread compound and make up joints as slow as possible again to the MUT of step 1 and they are ready to be run.

    Proper Torque Application 

    Before running pipe or BHA, make sure sufficient make-up torque (MUT) is applied to the connection.

    BHA will likely be exposed to dynamics (vibrations). Stick and slip is very damageable to connections and can induce higher-than-planned torque. Rotary shoulder connections are left vulnerable to downhole make-up if not given proper MUT before running.

    Do not hesitate to apply the maximum recommended MUT of our performance specifications.
