Applications: Field Results

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

Through its patented Anti Stick-slip Tool (AST), Tomax provides a stable, safe drilling environment, free from stick-slip vibrations produced in the process of cutting through problematic underground formations. The suppression of stick-slip vibrations will also release energy for faster rates of penetration (ROP). As a result, the use of AST will always add significant value where the drilling operation faces risk from stick-slip vibrations.
