Latest Patents
One of his latest patents is the "Bi-directional annulus seal." This invention features a wellhead seal assembly that forms a metal-to-metal seal between inner and outer wellhead members. The design includes a metal seal ring with inner and outer walls separated by a slot. A lock ring is incorporated with grooves to secure the inner wellhead member to the outer wellhead member during installation. Additionally, an energizing ring with a C-ring captured on its inner surface is utilized. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages the surface of the inner wellhead member, effectively locking the seal assembly in place.
Another significant patent by Ellis is the "Flex-lock metal seal system for wellhead members." This assembly also forms a metal-to-metal seal between the inner and outer wellhead members. It features a metal seal ring with inner and outer conical walls separated by a tapered slot. The energizing ring in this design has inner and outer annular members separated by an annular cavity. As the energizing ring is moved further into the slot, the cavity width decreases, providing a preloaded radial force to the seal ring.
