Latest Patents

John Macrae holds a patent for a high-pressure casing patch. This invention features a casing patch that utilizes one or more fins which elastically flex to accommodate a casing stub. The casing stub is prepared with a dressing tool that employs a special mill to achieve the necessary finish on its outer surface before the insertion of the casing patch. The flexible fins provide a metal-to-metal seal to the outer surface of the casing patch, while a grip assembly secures the joint. In specific applications, the fins can be combined with a resilient seal, ensuring that the wall thickness of the joint can be maintained at thicker values compared to previous designs. This innovation guarantees a pressure rating for the joint that is at least equal to that of the casing stub.
