Latest Patents

Sellers holds a patent for a Multi-layered Temperature Responsive Pressure Isolation Device. This innovative sealing element comprises two distinct materials with different melting points. The outer shell material has a higher melting point than the inner core material, which can be a low melting point metal, plastic, or polymer. Positioned in the wellbore, the seal responds to heating at a selected temperature, such as the bottom hole static temperature. Upon reaching this temperature, the core material melts or softens, allowing the outer shell's elastic modulus to decrease. This change facilitates longitudinal compression and radial expansion of the sealing element. The inner material can also thermally expand, assisting in the radial expansion of the outer shell. This design enables the sealing element to provide a metal-to-metal seal with casing or tubing, promoting controlled compression, expansion, and sealing.
