  • High pressure well radioisotope injection system
    Patent number: 4659925
    Abstract: This invention relates to a system for injecting radioactive tracers into a fluid line such as that of an injection oil well. The radioactive material is located in a vial within the shipping container. The vial is pierced by fluid carrying lines and the radioactive material is then transferred via the carrier fluid to a previously evacuated pressure flask. The pressure flask is then isolated from the line leading to the vial and fluid from the high pressure injection line is introduced into the pressure flask to flush the radioactive material into the high pressure line and thus into the injection well.
