Why use Torque Rings for casing rotation ?


In critical situations like casing drilling or rotation it is necessary to be certain of the outcome rather than rely on hindsight, after the fact of failure.


When using a typical API connection during casing drilling it will be necessary to know the rotational torque limits and operating envelope of your casing string when in open hole and at the tool face.


A weak connection may result in "twist or back off", "washout" or similar and the resulting costs of remedial activities.


Lets take an example of how torque rings will improve the torsional capacity of a typical 9 5/8 BTC connection at 47ppf and grade L80.


​With no torque rings we can make this connection up on surface to approx 12,000 ftlbs at mid-triangle (optimum).


With MLT rings in place we can make this up to 49,451 ftlbs max.


With DTR in place we can make this up to  58,480 ftlbs max.


This increase provides a large window of additional torque with which to address planned drilling activity.


It also provides the drilling engineer with the ability to save on the costs of hi-torque premium threaded casing for a more cost effective API connection with torque rings. (This assumes the presence of hydrocarbons are not a critical factor in decision making)


Torque Rings


Torque rings provide API threaded and coupled connections (BTC,LTC,STC,EUE) with greater torsional strength and provide the following benefits:


  • ​Improved torsional capacity to connection enabling rotation of casing strings for reaming or drilling
  • Improved flow characteristics within a casing or tubing string
  • Improved connection lifecycle due to less erosion
  • Improved flow characteristics in completion tubing
  • Reduced recuts and re-threads in work strings due to reduced overtorquing

Volant Multi Lobe Torque Rings (MLT)


ERA, as distributors for Volant Products, provide sales and installation services for the Volant range of MLT rings.
