Title: David MacFarlane: Innovator in Subsea Wellhead Technology
Introduction
David MacFarlane is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of petroleum engineering, particularly in subsea wellhead systems. His innovative approach has led to the development of a unique casing hanger system that enhances the efficiency and safety of well operations.
Latest Patents
David MacFarlane holds a patent for a "Nested stack-down casing hanger system for subsea wellheads." This wellhead system is designed for petroleum-producing wells and features a "stack-down" casing hanger configuration. In this system, the hanger for each successively smaller diameter casing string is landed or "nested" within the hanger for the next larger casing string. This design allows for the independent retrieval of the pack-off for each casing hanger, enabling fluid communication to be established with any of the casing annuli after all casing strings and hangers have been installed. Consequently, the pressure in each annulus can be monitored while the well is in production mode. He has 1 patent to his name.
