ABSTRACT:
Systems and processes are provided for facilitating transfer of downhole devices through a reversibly sealable wellhead fixture capping a well under pressure, without jeopardizing operators, equipment, or the well itself. An open ended pressurizable vessel is provided that is sized and shaped to accommodate a substantial portion of a particular downhole device, such as a logging tool. The vessel includes a mating flange for coupling its open end to a reversibly sealable wellhead fixture. A pressure can be equalized between an internal cavity of the pressurizable vessel and the wellbore. Once the pressure has been equalized, a channel can be opened between the pressurizable vessel and the wellbore, allowing for transfer of the downhole device in a preferred direction, either into or out of the wellbore. One or more robotic systems can be provided to further expedite manipulation of at least one of the tool and the vessel.
