Abstract

A disclosed pulsed-power drill bit includes a bit body, an electrode coupled to the bit body and having a distal portion, a ground ring coupled to the bit body and having a distal portion for engaging with sidewall surfaces of a wellbore and defining an outer diameter of the ground ring, and actuatable, electrically conductive fins each coupled to the ground ring such that the fin and the distal portion of the ground ring are electrically continuous. Each fin is positioned such that when actuated, a distal portion of the fin is extended in a direction away from the bit body, increasing the effective outer diameter of the ground ring, or is retracted, decreasing the effective outer diameter of the ground ring. The fins may be spring loaded within a track, channel, or slot between fluid flow ports and may be actuated individually or collectively.
