Permanent or removable positioning apparatus and method for downhole tool operations
First Claim
1. A tool positioning apparatus for positioning a downhole tool within a wellbore, comprising:
- an anchor assembly inserted within an interior surface of the wellbore and comprising an inner diameter having a selected profile comprising a plurality of grooves formed therein for selective engagement with a discrete complementary profile of the downhole tool, wherein the discrete complementary profile comprises one or more protruding members for selective engagement with the selected profile when the downhole tool is inserted into the anchor assembly, wherein each of the grooves of the plurality of grooves comprises a no-go shoulder configured to prevent movement of the downhole tool in one direction and permit movement of the downhole tool in a second direction, wherein the selected profile comprises a biased member configured to clock the complementary profile in a selective azimuthal direction and position;
one or more slips configured to engage the interior surface of the wellbore or a conduit after completion processes have taken place within the wellbore; and
a mandrel engaged with the anchor assembly, wherein the mandrel comprises a plurality of cones extending therefrom, wherein the plurality of cones comprises a first cone facing a first end of the tool positioning apparatus and a second cone facing a second end of the tool positioning apparatus to force the one or more slips against the interior surface in response to a compression force, and wherein the tool positioning apparatus is removable from the interior surface of the wellbore or the conduit.

Abstract
A system and method for positioning a tool within a wellbore, wherein the interior surface of a positioning apparatus includes one or more pluralities of grooves, each defining a selected profile. A tool is lowered into the positioning apparatus, having a blade in communication therewith. The blade includes a plurality of protruding members, which define a profile complementary to at least one of the selected profiles formed by one of the pluralities of positioning apparatus grooves. A biasing member, in communication with the blade, can continually bias the blade toward the interior surface of the positioning apparatus to cause the profile of the blade to engage within the corresponding complementary profile of the positioning apparatus. Positioning a tool in this manner is advantageous for locating cutting tools at a precise location to sever a joint, perforate casing or stack multiple tool operations at a fixed, targeted point within a wellbore.

11. A method for positioning a tool positioning apparatus, comprising the steps of:
-
lowering the tool positioning apparatus within an interior surface of a wellbore or a conduit after completion processes have taken place within the wellbore, wherein the tool positioning apparatus comprises an anchor assembly and a mandrel having a plurality of cones extending therefrom, wherein the plurality of cones comprises a first cone and a second cone, wherein the anchor assembly further comprises an inner diameter having a selected profile comprising a plurality of grooves formed therein for selective engagement with a discrete complementary profile comprising one or more protruding members of a tool, wherein each of the grooves in the plurality of grooves comprises a no-go shoulder configured to prevent movement of the tool in one direction and permit movement of the tool in a second direction; compressing one or more slips with the plurality of cones to cause the one or more slips to engage the interior surface of the wellbore or the conduit; lowering the tool into the tool positioning apparatus and clocking the tool into a selective azimuthal direction and position using a biased member of the anchor assembly for selective engagement of the discrete complementary profile of the tool with the selected profile of the anchor assembly; and removing the tool positioning apparatus from the interior surface of the wellbore or the conduit. - View Dependent Claims (12, 13, 14, 15, 16, 17)
