Abstract
A technique enables anchoring of a tool in a wellbore. The technique provides traction against a well component without creating high stress concentrations that weaken the well component. An anchoring device comprises anchoring members that are selectively movable to an expanded configuration for anchoring the tool. The anchoring members have traction surfaces able to selectively engage a smooth anchoring surface of the well component at any desired location along the well component. Each traction surface is formed to facilitate traction while minimizing stress concentration.
