  • Externally guided and directed field induction resistivity tool
    Patent number: 8072221
    Abstract: An induction resistivity tool incorporated into a downhole tool string comprises an outer wall of a downhole component having an outer surface, and at least one induction transmitter assembly disposed along the outer surface. The transmitter assembly includes at least one induction transmitter coil which is wound about one or more transmitter cores. The transmitter assembly is adapted to create electromagnetic fields that originate the induction signal from outside the outer wall while substantially preventing the induction signal from entering the outer wall.
    Type: Grant

    Date of Patent: December 6, 2011
    Assignee: Schlumberger Technology Corporation
    Inventors: Harold L. Snyder, Jr., Paula Turner
  • Induction Resistivity Tool that Generates Directed Induced Fields
    Publication number: 20110227578
    Abstract: In one aspect of the present invention, an induction resistivity tool includes an induction transmitter and an induction receiver located along the length of the tool. The transmitter is located adjacent at least one induction bucking coils of the tool. When activated the bucking coils are configured to direct a field transmitted by the induction transmitter away from the tool at an angle from the central axis of the tool.
    Type: Application

  • Externally guided and directed field induction resistivity tool
    Patent number: 7982463
    Abstract: In one aspect an induction resistivity tool incorporated into a downhole tool string comprises an outer wall of a downhole component comprising an outer diameter and at least one induction transmitter assembly disposed along the outer diameter. The at least one transmitter assembly comprises at least one induction transmitter coil wound about at least one core. The at least one transmitter coil is adapted to project an induction signal outward from the outer wall when the at least one transmitter coil is carrying an electrical current. The transmitter assembly is adapted to create electromagnetic fields that originate the induction signal from outside the outer wall and substantially prevent the signal from entering the outer wall.
