ABSTRACT:
A pulling tool and method for pulling an operating tool from a downhole location in a wellbore in which an elongated tubular housing assembly is connectable to a section of reeled tubing and defines a longitudinal bore through which fluid passes from said reeled tubing. A passage extends through the housing assembly and communicates with the longitudinal bore of the housing assembly for discharging the fluid against the wall of the wellbore and the fishing neck of the operating tool to clean same. A latching assembly is disposed on the housing assembly for latching to the fishing neck of the operating tool as the housing assembly is inserted into the fishing neck to enable the fishing neck and the operating tool to be pulled from the wellbore. In the event the operating tool cannot be pulled from the wellbore, the flow of fluid through the passage of the housing assembly can be blocked to enable the fluid pressure to build up in the bore of the housing assembly, in which case the housing assembly operates to release the fishing neck to enable the housing assembly to be removed from the wellbore.
