TOURMALINE OIL CORP
34% savings in
Tourmaline Oil Corp – the largest natural gas producer in Canada, is pushing to be one of the most sustainable energy enterprises in North America.
Tomax has supplied AST regulators to Tourmaline since 2020. The goal is to burn less diesel through improved drilling efficiency. The savings in specific carbon emissions was 34% in 2021 and keeps improving. The photo shows the Ensign 897 rig on a multi-well site.
The AST consists of a mechanical-hydraulic converter placed in the lower part of the drill string.
Optimized drilling process
Under normal, stable conditions, the unit will transfer torque and weight to the bit as a passive part of the Bottom Hole Assembly (BHA).
However, if the loading of the PDC bit becomes unstable, the AST regulator will apply its algorithm to stabilize the cut. The result is an optimized drilling process with less wear and vibration.
Prevents destructive vibrations
In practical terms, this means that the momentary response/closed-loop function of the AST prevents the escalation of local instabilities into destructive vibrations. The tool functions continuously, and no reset is required.
Axial excitation is how a PDC drill-bit solves overload in a conventional configuration
The AST regulator adapts the load to the available torque. This happens in less than 30 milliseconds and provides for a steady cut
Downhole tool sizes
Use of the AST requires no changes to standard drilling practices. The tool has a wide working range which eliminates the need for service personnel.
Wells operating with Tomax
In recent years, the Tomax AST has been the fastest growing new technology in deep drilling.
