  • Method and apparatus for controlling well pressure in open-ended casing
    Patent number: 7021385
    Abstract: A system and method for preventing blowouts during the deployment of a casing string into a wellbore. The system includes securing a casing coupling to a casing string and securing a retrievable check valve within the casing coupling. The retrievable check valve allows fluid from the surface to be pumped through the retrievable check valve. However, the retrievable check valve prevents upward fluid flow from the wellbore through the retrievable check valve to the surface.
    Type: Grant
