Selective plug and method

Abstract

A selective plug including a body; and a rotator configuration in operable communication with the body capable of causing the plug to selectively pass a number of borehole restrictions to reach and engage a target restriction and method.

1 . A selective plug comprising:
 a body;   a rotator configuration in operable communication with the body capable of causing the plug to selectively pass a number of borehole restrictions to reach and engage a target restriction.   
     
     
         2 . The selective plug as claimed in  claim 1  wherein the rotator configuration is in operable communication with a collet. 
     
     
         3 . The selective plug as claimed in  claim 2  wherein the collet includes a lug that extends into the rotator. 
     
     
         4 . The selective plug as claimed in  claim 2  wherein the rotator includes a J-Slot configuration thereon responsive to movement of the collet. 
     
     
         5 . The selective plug as claimed in  claim 1  wherein the rotator configuration further includes a key interactive with the rotator configuration to prevent rotation thereof after a selected number of increments. 
     
     
         6 . The selective plug as claimed in  claim 5  wherein the key interacts with one of a plurality of step profile teeth. 
     
     
         7 . The selective plug as claimed in  claim 1  wherein the body includes a flared end. 
     
     
         8 . The selective plug as claimed in  claim 7  wherein the flared end supports one or more collet fingers of a collet mounted at the body. 
     
     
         9 . The selective plug as claimed in  claim 1  wherein the rotator configuration includes a biasing arrangement. 
     
     
         10 . The selective plug as claimed in  claim 9  wherein biasing arrangement is a spring. 
     
     
         11 . A method for conducting borehole operations comprising:
 determining where in a borehole an operation is desired;   setting a selective plug; and   deploying the selective plug into the borehole.
