Embodiment Construction

[0033] The present application relates to autonomous downhole tools that are moved at least a partial length along a well bore via an external force. In an embodiment, the autonomous downhole tool is moved along substantially the entire length of the well bore via an external force. In various embodiments, the external force is provided by a cable, by hydraulic pressure, by force of gravity, or by a combination thereof. In an embodiment, the autonomous downhole tool is not self-transportable via an onboard power supply. In an embodiment, the autonomous downhole tool is non-robotic. In an embodiment, the autonomous downhole tool does not provide its own locomotion. In an embodiment, the autonomous downhole tool is not self-propelling. In an embodiment, the autonomous downhole tool does not move within the well bore under its own power. In an embodiment, the autonomous downhole tool does not move within the well bore via traction with the well bore wall. In an embodiment, the autonomo...

Abstract

An autonomous downhole tool for use in a well bore is moved along at least a partial length of the well bore via an external force, and the tool is self-operable to perform one or more functions at one or more locations within the well bore.. A method for operating a downhole tool within a well bore comprises deploying the tool along at least a partial length of the well bore via an external force, and self-activating one or more functions of the tool, wherein the tool does not receive command communications from the surface.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application Ser. No. 60 / 567,743 filed May 3, 2004 and entitled “Autonomous Navigation for a Downhole Tool,” by Wesley Jay Burris II, et al, which is incorporated herein by reference for all purposes.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. REFERENCE TO A MICROFICHE APPENDIX [0003] Not applicable. FIELD OF THE INVENTION [0004] The present application relates to autonomous downhole tools that are moved in a well bore via an external force, and methods of servicing a well bore using such tools. The present application also relates to autonomous downhole tools that are self-navigating without receiving location communications from an external source, such as from the surface or another downhole component. The present application further relates to autonomous downhole tools that are self-activating without rec...
