Objective
Precision under pressure
The PDC cutters rely on an accurate force-feed to deliver their unique capacity for efficiency and durability. The bottom end of a long, flexible drill-string is possibly the worst place for that.
Results
Stabilizing deep
drilling performance
Even with such an unfavorable position, PDC bits outperforms all other solutions for deep drilling. That says a lot about its potential.
Tomax put the AST (Anti Stick-slip Tool) in the string to help stabilize the bottom hole forces and harmonics.The improvements for both efficiency and distance has made AST the fastest growing new technology in drilling.
Academia has multiple methods for modeling drilling systems including the spring characteristics on the rock-cutting interface. From this the scientists have been able to prove the AST contribution and even optimize the response of the AST regulator.

About the author
Nils Reimers founded Tomax AS in 2005. The company has since led the way for downhole regulators through increasing efficiency gains and corresponding utilization. By 2022, the service industry had come up with seven (7) alternatives to the Tomax tool. But Tomax still led the way by a large margin. In 2023 Tomax had 1837 well deployments and Mr. Reimers was awarded the highest recognition from SPE Norway and the Norwegian oil industry: Industry Professional of the Year.
