Title: W L Lennon: Innovator in Well Drilling Technology
Introduction
W L Lennon is a notable inventor based in Corsicana, TX (US), recognized for his contributions to well drilling technology. He holds 2 patents that showcase his innovative approach to improving drilling operations.
Latest Patents
One of his latest patents is the "Whipstock Starter Mill Assembly." This invention is designed to mill a window through the casing of a well, allowing for a change in the direction of drilling. The starter mill features a bearing nose that indicates the completion of the milling process. As the milling nears completion, the bearing nose becomes wedged between the whipstock face and the casing, preventing further downhole movement. This design allows the work string to continue rotating, signaling the end of the milling operation. The cutters are strategically spaced from the bearing nose to ensure the casing window is completed effectively.
Another significant patent is the "Section Mill with Multiple Cutting Blades." This section mill is engineered to cut through well casing using multiple sets of cutting blades that can be selectively engaged. As the blades dull, a succeeding set can be utilized, ensuring continuous cutting operations. The central mandrel of the mill has offset cammed surfaces that engage the cutting blades, causing them to expand outwardly. The mandrel is displaced axially by a piston affected by hydraulic pressure, allowing for efficient operation.
