Marker plug

Abstract

An arrangement for visually identifying cuttings from different stages in a well is provided. In aspects of the disclosure, plugs may have different markers according to their respective position in a well, thereby allowing operators to visually identify locations in a well.

What is claimed is: 
     
         1 . A method, comprising:
 placing a marker plug with identifier within a wellbore;   transferring the marker plug with the identifier to a position in a wellbore for setting;   setting the marker plug with the identifier in the position in the wellbore desired for setting;   drilling the marker plug with identifier from the wellbore such that the drilling of the marker plug releases the identifier; and   transferring at least a portion of the identifier for transfer to an uphole environment.   
     
     
         2 . The method according to  claim 1 , wherein the setting the marker plug with identifier is performed with a wireline setting tool. 
     
     
         3 . The method according to  claim 1 , wherein the setting the marker plug with identifier is performed with a coiled drilling tubing setting tool. 
     
     
         4 . The method according to  claim 1 , wherein the setting the marker plug with identifier is performed with a slick line setting tool. 
     
     
         5 . The method according to  claim 1 , wherein the setting the marker plug is with a dropped ball. 
     
     
         6 . The method according to  claim 1 , wherein the identifier is a colorant within a body of the marker plug. 
     
     
         7 . The method according to  claim 1 , wherein the identifier is a colorant packet within a body of the marker plug. 
     
     
         8 . The method according to  claim 7 , wherein the colorant packet is inserted into the body of the marker plug prior to placing the marker plug within the wellbore. 
     
     
         9 . The method according to  claim 1 , further comprising:
 identifying the portion of the identifier at the uphole identification area.   
     
     
         10 . A marker plug, comprising:
 a body configured with an opening;   an identifier one of configured with the body and within the body, wherein the identifier is one of a colorant, a packet of colorant and a material; and   an anchor attached to the body, the anchor configured to grip a side wall of a drill string tubular.   
     
     
         11 . The marker plug according to  claim 10 , wherein the opening is configured to accept a dropped ball in a drill string. 
     
     
         12 . The marker plug according to  claim 10 , wherein the material is a metal. 
     
     
         13 . The marker plug according to  claim 10 , wherein the material is a radioactive material. 
     
     
         14 . The marker plug according to  claim 10 , wherein the material is a fluorescent material.
