Title: Steve Johnstone: Innovator in Hydraulic Technology

Introduction

Steve Johnstone is a notable inventor based in Aberdeen, GB. He has made significant contributions to the field of hydraulic technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges. His work primarily focuses on enhancing the efficiency and functionality of hydraulic systems.

Latest Patents

One of Johnstone's latest patents is an "Alternative packer setting method." This invention involves delivering fluid setting pressure to a hydraulically set well packer through an external conduit strapped to the exterior of a well workstring above the packer assembly. The design allows for the continuity of the external conduit to extend past the packer assembly, following a flow channel along the mandrel sleeve thickness. This external conduit may also serve other well functions, such as chemical delivery. A calibrated rupture element in the external conduit initially obstructs flow, ensuring that fluid pressure is first directed to the packer setting pressure chamber. After the packer is set, the fluid pressure in the external conduit is increased to rupture the calibrated element, allowing for additional well service functions.

Another significant patent by Johnstone is the "Pressure control system for a wet connect/disconnect hydraulic control line connector." This system includes a reservoir and a piston that is biased by hydrostatic pressure or an atmospheric chamber. The pressure in the hydraulic line is controllable based on the existence or placement of the atmospheric chamber. The method for controlling pressure involves running the control system and biasing the piston to manage pressure effectively.
