HALF A MILLION FEET IN THE SHALE PLAY The AST is being used in an increasing number of applications: STRINGERS In less than two years, the patented Anti Stick-slip Tool (AST) from Tomax has passed half a million feet in the US Shale Play. The AST is used where the drilling is predicted to be challenging, and this makes the milestone particularly significant. The AST is a mechanical regulator placed downhole that simply saves the drilling system from being overloaded if the drill-bit bites too deep. By absorbing the excessive forces (torsional and/or axial), the AST also acts as an energy store that automatically feeds its energy back to the drill-bit if loading drops. The improved stability provided by the AST allows the driller to put more power into the system from surface, in order to increase the Rate of Penetration (ROP) - without increasing the risk from vibrations. The expanded operational window also permits use of more aggressive drill-bits that can yield further ROP improvements.
