Title: Dale J Castille: Innovator in Wellbore Tubular Technology
Introduction
Dale J Castille is a notable inventor based in Lafayette, LA (US), recognized for his contributions to the field of wellbore tubular technology. With a total of 6 patents to his name, Castille has developed innovative solutions that enhance the efficiency and effectiveness of drilling operations.
Latest Patents
Among his latest patents is the "Method and apparatus for repair drill pipe and other tubular goods, including threaded connections thereof." This invention features a re-facing apparatus designed for pipe threaded connections, which includes independent machining stations for both pin-end (male) and box-end (female) connections. The apparatus allows for the restoration of torque shoulders by machining the face of each shoulder using custom spindles and cross slides. This innovative design can be set up over existing pipe racks, enabling pipe sections to be rolled through for processing. It is particularly beneficial for pipe storage and inspection facilities, as it allows for the re-facing of out-of-specification pipe connections without incurring significant transportation or machine shop expenses.
Another significant patent is the "Apparatus and method for connecting wellbore tubulars." This invention discloses a control system for a power tong unit that includes a power spinner and three power jaws. The system is designed to control the grip pressure applied by the power jaws to facilitate the connection of wellbore tubulars. It allows for a reduced grip pressure when the power spinner is activated, enabling high rotation speeds with low torque. Conversely, it applies high grip pressure for final making up or initial breaking out of the tubulars, ensuring a secure connection.
