  • System and method for communicating between a drill string and a logging instrument
    Patent number: 9347277
    Abstract: A wireline configurable well logging instrument is connected to a drill pipe carrier and movable from a retracted position to an extended position. The drill pipe carrier is positioned on a pipe string that may comprise a portion of wired pipes communicatively coupled at each joint. Communication between the drill pipe carrier and the well logging instrument includes the use of inductive couplers, wires and combinations thereof.

  • Power systems for wireline well service using wired pipe string
    Patent number: 8544534
    Abstract: A wellbore instrument system includes a pipe string extending from earth's surface to a selected depth in a wellbore. The pipe string includes at least one of an electrical conductor and an optical fiber signal channel. A power sub including an electric power source is coupled proximate a lower end of the pipe string. At least one electrically powered wireline configurable wellbore instrument is coupled to the power source in the sub.
