US Patent 11959365 Metal seal for liner drilling
Article
Patent abstract
Systems and methods of forming a seal employ a robust metal sealing unit for tubulars used in rotary drilling. Specifically, eutectic alloy is used to seal a tubular to a wellbore after drilling. A downhole heater melts the alloy, allowing the alloy to expand and drain before it cools and solidifies between the wellbore and tubular, forming a gas tight seal.
