Abstract
A multilateral reference point sleeve includes a tubular member configured to be received in a tubing string of a wellbore. The tubular member has an uphole end and a downhole end. The uphole end is angled to define an orientation profile, and the orientation profile has an orientation slot extending therefrom. A method for orienting a tool in a wellbore includes running the multilateral reference point sleeve into the casing in the wellbore, anchoring the sleeve to an inner surface of the casing, running the tool into the tubing string, causing a pin on the tool to engage the orientation profile on the sleeve, and causing the pin on the tool to engage the orientation slot on the orientation profile.
Claims15
A multilateral orientation device comprising:
- a non-diverter tubular sleeve composed of a single piece of material at least a portion of which is circumferentially closed, said sleeve having a wall thickness selected to minimize restriction of a borehole in which the sleeve is installable, said thickness being insufficient to divert a tool and sufficient to orient a tool;
- an expandable section of the sleeve, said section being radially expandable to assume a larger circumferential dimension such that an interference fit with a wellbore in which the device is to be deployed is achievable;
- and
- an rotational orientation profile disposed at an axial end of said sleeve.
A method for orienting a tool in a wellbore, comprising:
- running a multilateral orientation device comprising a circumferentially closed single piece sleeve, said sleeve having a material thickness insufficient to divert another tool and sufficient to orient a tool, the sleeve further including at least a portion thereof configured to expand radially into interference contact with said wellbore;
- expanding said multilateral orientation device to achieve an interference fit with an inner surface of said wellbore to permanently anchor said multilateral orientation device in said wellbore;
- running said tool into said wellbore;
- causing a pin on said tool to engage an orientation profile on said multilateral orientation device sleeve such that said tool is oriented by an interaction between said pin and said orientation profile.
A multilateral orientation device comprising:
- a non-diverter tubular sleeve composed of a single piece of material at least a portion of which is circumferentially closed, said sleeve having a wall thickness selected to minimize restriction of a borehole in which the sleeve is installable, said thickness being insufficient to divert a tool and sufficient to orient a tool;
- an expandable section of the sleeve, said section being radially expandable to assume a larger circumferential dimension such that an interference fit with a welibore in which the device is to be deployed is achievable, said section of the sleeve being at a downhole end of the sleeve and having a lesser thickness than an uphole end of the sleeve;
- and
- an orientation profile disposed at an axial end of said sleeve.
A multilateral reference point sleeve, comprising:
- a tubular member at least a portion of which is circumferentially closed, said member having a wall thickness selected to minimize restriction of a borehole in which said sleeve is installable, said member installable subsequent to installation of a casing in a wellbore to be received in direct contact with the casing of the wellbore, said tubular member having an uphole end and a downhole end, said uphole end defining an orientation profile configured to cause a pin on a separate tool to ride along said orientation profile causing said separate tool to orientate.
