Abstract
Methods and assemblies that can be used to orient a second pipe with respect to a first pipe in a wellbore are disclosed. The first pipe may be a casing string that includes one or more recessed latch couplings, and the second pipe may be a tubing string that includes one more complementary radially extendable latch keys that may be received within the latch couplings. The tubing string may include one or more switches associated with the latch keys that are actuated when the latch keys are received within the latch couplings. The actuation of the switches is communicated to an operator at the surface via control lines within the tubing string.
Claims23
A system capable of being disposed in a wellbore, the system comprising:
- a first pipe having a wall a portion of which defines a target, the wall defining an inner region;
- a second pipe capable of being disposed in the inner region of the first pipe, a portion of the second pipe having a second pipe wall a portion of which defines a target;
- a device carried by at least one of the first pipe or second pipe and capable of preventing constraining relative movement of the two pipes at least rotationally or axially;
- a switch coupled to said device so as to actuate when the device is in a particular configuration;
- and
- a circuit operatively coupled between said switch and an indicator for notifying an operator of the configuration of said switch.
A method for orienting a tubing string with respect to a casing string in a wellbore, the casing string having a latch coupling and a casing string window associated with a lateral wellbore, the method comprising:
- providing a tubing string having a tubing string window and a latch key;
- disposing the tubing string into the wellbore to a position at which at least part of the tubing string window is adjacent to at least part of the casing string window and at which the latch coupling is configured to receive the latch key to prevent at least one of the group consisting of rotation and axial translation of the tubing string with respect to the casing string;
- actuating a switch by said latch key when said latch key is received in said latch coupling;
- and
- providing a signal to an operator when said switch is actuated.
A method for orienting a tubing string with respect to a casing string in a wellbore, the casing string having a first and second latch couplings and first and second casing string windows associated with first and second lateral bores, the method comprising:
- providing a tubing string having a first tubing string window and a first latch key located in a first section of said tubing string and a second tubing string window and a second latch key located in a second section of said tubing string;
- providing within said tubing string a joint that demarcates said first section from said second section and that enables movement of said second section with respect to the first section;
- disposing the tubing string into the casing string to a position at which at least part of the first tubing string window is adjacent to at least part of the first casing string window and at which the first latch coupling is configured to receive the first latch key to prevent at least one of the group consisting of rotation and axial translation of the first section of said tubing string with respect to the casing string;
- actuating a first switch by said first latch key when said first latch key is received in said first latch coupling;
- and
- providing a signal to an operator by a circuit when said first switch is actuated.
