About Tomax AS
Tomax: Enhancing Drilling Efficiency Through Innovative Technology Founded in Norway in 2005, Tomax is a company dedicated to developing cutting-edge technologies that systematically improve drilling efficiency. This includes extending drill bit longevity and enhancing operational reliability. Tomax has a global presence with subsidiaries in key oil and gas hubs, including Houston, Aberdeen, Dubai, Dammam, and Kuala Lumpur.
The Value of Tomax Technology
Traditional deep drilling methods often struggle to balance efficiency with risk. Conventional approaches to reduce risk, like using swept-back PDC cutters and limiting drilling parameters, inadvertently hinder efficiency. And these methods do not change the likelihood self-excitation, or "chatter," at the bit-rock interface. This chatter leads to slower drilling speeds and accelerated wear on the cutters, ultimately reducing the footage drilled. The Tomax Anti Stick-slip Tool (AST) directly addresses this problem. The AST counteracts the self-excitation caused by cutter projection, allowing for significant increases in drilling efficiency while simultaneously boosting drill bit footage from reduced PDC wear. The increase in the system efficiency also mitigates the risk associated with vibrations: With a more effective drilling process, less energy can be transformed into destructive vibrations, such as High Frequency Torsional Oscillations or HFTO. Tomax's latest generation of AST tools are highly versatile, utilized in over 1,400 advanced wells annually. They are designed to meet a wide range of downhole challenges with a practically unlimited operational range, eliminating the need for field adaptations or on-site support.
Principle of Operation
The Tomax AST is engineered to counteract torsional sticking and axial self-excitation at the bottom of a long drill-string. These instabilities are a common and often unavoidable challenge in deep drilling, where the axial force (WOB) is generated from an unsuspended portion of a drill-string that is otherwise under tension and in contact with the wellbore walls. The AST system works by producing a linear counteraction through its hydro-mechanical design. The operational constant of the reactive algorithm is worked out through computer supported mathematical modelling.
