Title: Jon E Hed: Innovator in Subsea Technology

Introduction

Jon E Hed is a prominent inventor based in Houston, Texas, known for his significant contributions to subsea technology. With a total of 10 patents to his name, Hed has made remarkable advancements in the field of wellhead assemblies and plug installation systems.

Latest Patents

One of his latest patents is the Tubing Annulus Valve, which features a subsea wellhead assembly equipped with a tubing hanger that includes both a tubing annulus passage and a production passage. This innovative design incorporates a metal-sealing shuttle valve that effectively blocks upward flow through the tubing annulus passage. The shuttle valve is designed with a retention mechanism that prevents it from moving to the open position when fluid pressure is applied from above. After testing is completed, the running tool releases the retention mechanism, allowing the shuttle to close. Additionally, the assembly includes an engaging member that can be stroked downward into the tubing hanger annulus passage to move the shuttle valve to the open position for communication with the annulus.

Another notable patent is the Plug Installation System for Deep Water Subsea Wells. This invention utilizes a plug retrieval and installation tool designed for subsea wells that feature a production tree and a tubing hanger. The tool is equipped with a housing and connector that is lowered onto the upper end of the tree. An axially extendible stem within the housing is controlled by hydraulic fluid and is moved into the production passage of the tubing hanger. The installation and retrieval member mounted to the stem engages the plug, allowing it to be pulled upward or pushed downward for installation, all powered by a remotely operated vehicle (ROV).
