  • Method of signaling passage of objects using tattle-tale apparatus
    Patent number: 9683437
    Abstract: An electro-mechanical indicator system for signaling when a droppable object (such as, for example, a dart, plug or ball) is released during well cementing operations. A body section has first and second chambers divided by a fluid and pressure sealing barrier. A mechanical trigger mechanism is situated in the first chamber, which is exposed to elevated pressures and harsh wellbore fluids. Less robust components, such as sensor(s), power source(s), and signal device(s) located in the second chamber, remain isolated from the wellbore environment and elevated pressures.
    Type: Grant

    Date of Patent: June 20, 2017
    Assignee: Blackhawk Specialty Tools, LLC
