Positive locating feature of OptiPort
A system and method for treating a portion of a wellbore that includes a bottom hole assembly (BHA) connected to a work string. The BHA includes a packing element movable between an unset position and a set position and a locator device movable between retracted position and expanded positions. The locator device may be a locator collet. The locator collet may be expanded by a cone movable with respect to the collet. The expanded locator device is configured to engage a profile in a ported tubular within the wellbore. The engagement between the locator device and the profile selectively prevents further movement of the BHA and provides an indication of the location the BHA. The packing element may then be actuated and the wellbore treated through a port in the ported tubular. The BHA may then be moved to a different ported housing to treat another portion of the wellbore.
1. A bottom hole assembly (BHA) comprising:
one or more packing elements, the one or more packing elements movable between a retracted unset position and an expanded set position;
a locator device movable between a retracted position and an expanded position, wherein the locator device is movable from the expanded position to the retracted position while the one or more packing elements remain in the expanded set position;
a member moveable relative to the locator device, wherein the member moves the locator device to the expanded position;
a plurality of slips positioned between the one or more packing elements and the locator device; and
a plurality of drag blocks positioned between the one or more packing elements and the locator device.
2. The BHA of claim 1 , wherein the locator device comprises a locator collet.
3. The BHA of claim 2 , wherein the member further comprises a cone on a mandrel.
4. The BHA of claim 3 , wherein the cone is connected to the mandrel by a plurality of shearable devices.
5. The BHA of claim 4 , wherein the cone includes a plurality of grooves on an exterior surface.
6. The BHA of claim 5 , wherein a first force applied to the BHA moves the cone relative to the locator collet to move the locator collet to the expanded position.
7. The BHA of claim 6 , wherein a second force applied to the BHA after the application of the first force moves the one or more packing elements to the expanded set position and moves the cone from the locator collet to move the locator collet to the retracted position.
8. The BHA of claim 7 , wherein a third force applied to the BHA after the application of the second force moves the one or more packing elements to the retracted unset position.
9. The BHA of claim 8 , wherein a fourth force applied to the BHA after the application of the third force to move the one or more packing elements to the retracted unset position places the BHA in a run in hole configuration.
10. The BHA of claim 9 , wherein the application of a fifth force to the BHA when in the run in hole configuration moves the cone relative to the locator collet to move the locator collet to the expanded position.
11. The BHA of claim 10 , wherein the first, third, and fifth forces comprise tension and the second and fourth forces comprise compression.
12. The BHA of claim 11 , further comprising a j-slot track having a first position, a second position, a third position, and a fourth position along the j-slot track.
13. The BHA of claim 12 , wherein when a pin is located in the first position the locator collet is retracted and the one or more packing elements is in the retracted unset position.
14. The BHA of claim 13 , wherein when the pin is located in the second position the locator collet is expanded and the one or more packing elements is in the retracted unset position.
15. The BHA of claim 14 , wherein when the pin is located in the third position the locator collet is retracted and the one or more packing elements is in the expanded set position.
16. The BHA of claim 15 , wherein when the pin is located in the fourth position the locator collet is retracted and the one or more packing elements is in the retracted unset position.
17. The BHA of claim 16 , wherein tension is applied to the BHA to move the pin from the first position to the second position, wherein compression is applied to the BHA to move the pin from the second position to the third position, wherein tension is applied to the BHA to move the pin from the third position to the fourth position, and wherein compression is applied to the BHA to move the pin from the fourth position to the first position.
