Computer Analyzed Torque Monitoring

We believe that all connections should be torque monitored.

As wells are drilled to greater depths, the demands that are placed on the connections increase exponentially. This is why, at HES, we believe that all connections should be torque monitored.

HES utilizes some of the most advanced Computer Analyzed Torque Monitoring (CATM), equipment on the market. Combined with our highly qualified technicians, the results are easy to see. With this method you gain the following advantages:

  • The ability to ensure that all connections are made up properly and to manufacturing specifications
  • HES will catch any anomalies during the make up, preventing issues before they occur. Without the use of CATM and qualified staff, this would not be possible.
  • Receive detailed reports comprised of the make up of each connection, including rejected connections and detailed post jobs with comments on all aspects.
  • Record and analyze torque, turns, RPM, and (when applicable), shoulder points and delta torque on premium connections. All are factors HES uses to determine a properly made up connection.
  • The use of CATM allows us to intervene when necessary to save a connections from damage due to: Overly high RPM’s, over-torque, over-rotation, and bad alignment.

Since all torque values are only recommended under ideal conditions for proper make, it is vital to trust a company that understands this and knows how to account for real-world conditions such as:

  • Misalignment
  • Debris or containments in the threads
  • Couplings turning during make up or poor quality machining on threads

Due to the inaccuracy that hydraulic load cells have with temperature changes, HES works to eliminate any possible error. This is why all of our systems use only electronic load cells to measure torque accurately.

If requested, our CATM systems can be connected to the internet so that make up on the graphs can be monitored in real time from customers remotely.

Whether you are running an API connection, semi-premium or a premium connection, HES encourages CATM on all wells. With the amount of capital it takes to drill a well, one of the most integral steps to ensure your casing has integrity during fracturing operations, is utilizing a competent CATM company.

WinCatt is a software tool which interacts with external control hardware to provide real time monitoring and control of tubular connection power tong make-up. It has been developed jointly by FARR Canada Limited, and the Centre For Engineering Research Inc. (C-FER) or Farr's exclusive distribution. The graphical user interface and logical software structure combined with powerful control, data acquisition and presentation capabilities enable the user to easily specify make-up parameters, control the make-up process and evaluate quality.

Job reports submitted that fail to comply with the above standard creates a liability situation if there is a casing leak. Who's liable? Did the crews adhere to manufacture specification when running the casing? Was position considered during final torque? Was there a threading issue from the casing manufacture? Was the correct application of thread compounds chosen and applied?

The sole purpose of utilizing modern technology is to reduce the liability, and/or put the onus on the negligent party. Hybrid Energy Services Ltd has maintained extensive training to ensure our field operators are trained and knowledgeable running each casing connection. Connections are not simply "monitored" they are analyzed to ensure manufacture procedures and policies where attained prior to running the casing into the hole.
