  • System and method for autonomously performing a downhole well operation
    Patent number: 6843317
    Abstract: An autonomous system for performing a well operation at a predetermined location in a wellbore comprises a tool string having at least one well tool, a motive device for traversing the wellbore, and a control system adapted to position the tool string near the predetermined location. The control system comprises (i) a sensing system for detecting mass irregularities in the wellbore and (ii) a processor system having a processor with memory for storing at least one well log. The processor acts under programmed instructions to compare sensor signals to the stored well log to determine a tool string position in the wellbore. The control system also contains circuits for controlling the operation of the well tool and the motive device.

  • Arrangement and method for deploying downhole tools
    Patent number: 6520264
    Abstract: A pump-through electrical conductor line includes an electrically conductive wire, an insulative coating disposed over the electrically conductive wire, and a tubing having the electrically conductive wire with the insulative coating disposed thereover loosely positioned therein so as to form a non-obstructed annulus between the insulative coating and an inner surface of the tubing. An arrangement for downhole casing collar location includes a length of the pump-through electrical conductor line, a slickline running unit configured to deliver the pump-through electrical conductor line to a downhole environment, a plugging device disposed on a downhole end of the pump-through electrical conductor line, and a casing collar locator disposed on the pump-through electrical conductor line adjacent the plugging device.
