Abstract

A double acting jar enhancer tool is disclosed capable of storing energy to enhance both upward and downward impacts delivered by a drilling jar. The enhancer stores energy in a single energy storage means (40) (typically a single stack of bellville washer springs) irrespective of which direction it is moved, obviating separate energy storage means for upward and downward blows.
