Anti stick-slip tool
The Anti Stick-slip Tool (AST) from Tomax ensures stable loading of PDC bits in all kinds of rock. This allows the cutters to cross boundaries with minimal waste of energy and low risk from vibrations.
12,000+
Tomax has contributed to more effective drilling in more than 12,000 wells around the world.
Autonomous regulation of the drill-bit interface has proven useful for drillers aiming for continuous improvement of operational efficiency.
The millisecond response of the AST reduces losses to friction at the rock interface. This leaves more energy available to cut rock faster and at the same time reduces cutter heat and, consequently, wear.
Product development
Tomax Patents – Numbers and Validity
The Tomax AST is continuously improved through engineering, performance studies, and scientific research. Inventive elements producing improved effects are patented. Several patents apply to the current product.
Placement in BHA
The standard placement of the AST tool is on top of the non-magnetic portion of the BHA. This is the same for rotary steerable systems, downhole motors and rotary assemblies.
BHA configuration examples for RSS/Under Reamer BHA RSS/LWD BHA and motor BHA. For hard rock and high friction formations, a roller reamer above the AST is recommended.
Downhole
tool sizes
Use of the AST requires no changes to standard drilling practices. Each size has a wide working range which covers all practical drilling parameters including operation with Under-Reamers. Special TT-AST tools are available for Thru Tubing services.
