  • Methods and systems for orienting in a bore
    Patent number: 8376054
    Abstract: Assemblies that can be disposed in a subterranean bore are described. Certain assemblies can be used to orient a second pipe with respect to a first pipe in a bore. A second pipe can be rotationally oriented without breaking one or more control lines that may be associated or included with the second pipe by using a tool that orients the second pipe as the second pipe is moved toward a surface of the bore. In some embodiments, assemblies can be used to orient multiple portions of the second pipe with respect to multiple windows of the first pipe. The first pipe may be a casing string and the second pipe may be a tubing string.
