Title: David S. Rowley - Innovator in Drilling Technology
Introduction
David S. Rowley is a notable inventor based in Salt Lake City, UT, recognized for his significant contributions to drilling technology. With a total of five patents to his name, Rowley's work has greatly influenced the efficiency and effectiveness of coring devices used in various drilling applications.
Latest Patents
Rowley's most recent innovations include a coring device with an improved core sleeve and anti-gripping collar. This advanced coring device features a nonrotatable inner barrel within the outer driving structure of the drill string, which connects to a coring bit. A woven metal mesh sleeve is mounted outside the inner barrel, designed to constrict around the core as it is drawn upward during the coring operation, effectively preventing binding or jamming.
Another significant invention by Rowley is the composite heavy metal drill collar. This device is engineered for drilling boreholes in earth formations and consists of a structural steel outer jacket, which secures an annular heavy metal core of sintered tungsten. The design ensures that the jacket carries the loads encountered during drilling while the core increases the overall density and mass of the drill collar, minimizing the risk of producing a deviated well bore.
