Latest Patents

Among his latest patents is a "Packing element with timed setting sequence." This invention discloses a packing element that includes a sealing element positioned on the outer surface of a mandrel deployed in the wellbore. The sealing element is strategically placed in an annulus between the mandrel and a portion of the wellbore. It features a first cavity on its inner surface, which is proximate to the first end of the sealing element, and a second cavity that differs in size and is located near the second end. Additionally, the packing element incorporates first and second gauge rings at both ends of the sealing element.

Another significant patent is for "Sealing annular gaps in a well." This well tool includes an elongate mandrel and a seal assembly that can transition between an unset state and an axially compressed set state. The seal assembly features an annular elastomer seal element designed to radially deform into contact with the well wall when in the set state. An anti-extrusion ring compresses the seal element, creating a containing space with a garter spring embedded in the seal element. This design prevents excessive deformation of the seal element, enhancing its reliability.
