Introduction

John Mitchel Cobb is a notable inventor based in Humble, TX (US). He has made significant contributions to the field of hydraulic technology, holding a total of 3 patents. His work primarily focuses on innovations that enhance drilling assembly and reservoir control systems.

Latest Patents

Cobb's latest patents include a hydraulic jar and an overpressure relief mechanism designed for drilling assemblies. This hydraulic jar features a tubular housing, a mandrel within the housing, and an annulus that separates the mandrel from the housing. A key aspect of this invention is the pressure relief mechanism, which divides the annulus into two portions. This mechanism includes first and second annular members that engage when the pressure in the second annulus portion is below a predetermined value. The fluid flow path between the two portions varies in size based on the pressure, allowing for efficient operation under varying conditions. Another significant patent involves interventionless reservoir control systems. These systems provide a method for positively closing off a section of a wellbore, thereby enabling effective reservoir control. The design allows for selective closure of the wellbore completion section, which can be reopened upon reconnection of the upper and lower completion sections.
