  • Method for disposing naturally occurring radioactive material within a subterranean formation
    Patent number: 5489739
    Abstract: A method for disposing of radioactive material in a disposal area, which is accessible from the surface through a wellbore which contains a wellbore fluid. The method comprises the steps of: encapsulating the radioactive material within a container, placing the container in the wellbore, passing the container through the wellbore to the disposal area, and equalizing the differential pressure between the wellbore pressure and internal pressure within the container as the capsule descends within the wellbore, prior to the differential pressure reaching a magnitude which would exceed a design collapse rating of the container.
