Introduction
John W Hester is an accomplished inventor based in Houma, LA (US). He holds 2 patents that showcase his expertise in drilling technology. His innovative contributions have significantly impacted the field of well bore operations.
Latest Patents
One of his latest patents is a hole opener designed for use on drill strings in well bore enlargement operations. This invention features a bore follower extension and a stabilized cutter equipped with poly crystalline diamond compact cutter elements arranged in various cutting spiral patterns. Fluid jets are directed toward the cutter arrays and also sweep the opener cut formation in groove regions between the cutter arrays. Additionally, a hard metal chip covering is present on the follower extension to open pilot hole bridges, assisted by a nose jet. Blade form vortex barriers are strategically situated at the confluence of the cutter cleaning and formation sweeping fluid jets. The follower extension is tapered to enhance the upward velocity of fluid rising past it.
Another significant patent by Hester is a method of making a drill string stabilizer, specifically a drill collar stabilizer. This method involves providing a length of drill string or drill collar as the stabilizer body. A cylindrical section of thick-walled tubing is used, with an inside diameter matching the outside diameter of the stabilizer body. A plurality of helical and elongated sections from the cylindrical tubing are cut to form spiral blades, which are then attached to the stabilizer body in a circumferentially spaced row. The cylindrical section is selected to ensure that the blades have a predetermined radial thickness when attached. Each blade may also feature a tapered end surface to facilitate the tool's operation in the well bore.
