Abstract
A fluid bypass tool that can be incorporated into a fishing arrangement between a fluid-operated latching tool and a fluid-operated jarring tool. The latching tool is actuated with fluid from the surface to be latched to and unlatched from a stuck tool in the wellbore. The bypass tool permits fluid flow to the latching tool to be interrupted so that the jarring tool may be operated without risk of inadvertently causing the latching tool to unlatch from the stuck tool.
