The prevention of torsional vibrations or stick-slip is essential in the process of drilling exploration and production wells for oil and gas.

Through the patented Anti Stick-slip Tool (AST) Tomax can provide a stable, safe drilling environment free from stick-slip vibrations produced in the process of cutting hole through problematic underground formations. The suppression of the stick-slip vibrations will at the same time release energy for faster rates of penetration (ROP). This way the use of AST will always add significant value where the drilling operation faces risk from stick-slip vibrations.

Please contact us or use this web site to help configure the AST products into your plans.
