Title: The Innovative Contributions of John E. Gunnells

Introduction

John E. Gunnells is a notable inventor based in Broken Arrow, OK (US). He has made significant contributions to the field of subsurface safety valves through his innovative patent. His work exemplifies the intersection of engineering and safety in the oil and gas industry.

Latest Patents

Gunnells holds a patent for a "Switching apparatus between independent control systems for a subsurface safety valve." This system allows for the switching between redundant control systems for a subsurface safety valve (SSV) while isolating the closure spring from hydrostatic pressure in the control line that is not in use. The design features two control lines connected to discrete operating pistons, which are coupled to the flow tube. Each operating piston connects to a control rod, with the rods terminating near opposed ends of a pivoting member. This innovative mechanism ensures that pushing down on one rod pushes up on the other, maintaining the necessary force for the closure spring to function effectively.
