Abstract
A method and system allows periodic access the wrong way through one or more one-way valves installed in a fluid flow stream. Fluid can flow through the bypassed valves or through the tools used to bypass the valves such as those of a reciprocating production pump. A stab tool cooperates with a valve to unseat a ball from a ball seat so as to bypass the ball and pass through the ball seat. The stab tool can be conveyed by tubing for discharge of fluid through ports in the stab tool. In another aspect of the invention, a rod installed within a pump between a reciprocating uphole valve and a downhole valve is arranged so that when the pump is closed, the stab tool at the rod's lower end passes through the downhole valve and a projection at the rod's upper end passed though the uphole valve the pump is partially closed. Fluid can be pumped in reverse through the pump fluidize debris.
