Method and system delivering a tracer to a flow

Abstract

A tracer plug including a body configured to reside in a complementary opening in a separate structure. The body includes a tracer; a through-flow passage in the body; and wherein the tracer is disposed in fluid communication with the opening. A method for identifying fluid.

1 . A tracer plug comprising:
 a body configured to reside in a complementary opening in a separate structure, the body comprising a tracer;   a through-flow passage in the body; and   wherein the tracer is disposed in fluid communication with the opening.   
     
     
         2 . The tracer plug as claimed in  claim 1  wherein the body is tubular. 
     
     
         3 . The tracer plug as claimed in  claim 1  wherein the body is cylindrical. 
     
     
         4 . The tracer plug as claimed in  claim 1  wherein the body is threaded. 
     
     
         5 . The tracer plug as claimed in  claim 1  wherein the body includes wickers. 
     
     
         6 . The tracer plug as claimed in  claim 1  wherein the body is cylindrical. 
     
     
         7 . The tracer plug as claimed in  claim 1  wherein the body is frustoconical. 
     
     
         8 . The tracer plug as claimed in  claim 1  wherein the body houses the tracer. 
     
     
         9 . The tracer plug as claimed in  claim 1  wherein the body consists of the tracer. 
     
     
         10 . The tracer plug as claimed in  claim 1  wherein the passage is one or more passages. 
     
     
         11 . The tracer plug as claimed in  claim 1  wherein the plug further includes a housing disposed about the body. 
     
     
         12 . The tracer plug as claimed in  claim 11  wherein the housing is threaded. 
     
     
         13 . The tracer plug as claimed in  claim 11  wherein the housing is wickered. 
     
     
         14 . A borehole system comprising:
 a tubular having a port therein;   a tracer plug as claimed in  claim 1  in the port.   
     
     
         15 . The borehole system as claimed in  claim 14  further comprising a screen radially outward of the tubular and tracer plug. 
     
     
         16 . The borehole system as claimed in  claim 15  wherein the screen is a metal screen. 
     
     
         17 . The borehole system as claimed in  claim 15  wherein the screen is a shape memory material. 
     
     
         18 . A method for identifying fluid comprising:
 inserting a tracer plug as claimed in  claim 1  in a tubular string;   running the string into a borehole;   flowing fluid in the string;   analyzing the flowed fluid; and   identifying a tracer in the fluid.   
     
     
         19 . The method as claimed in  claim 18  wherein the inserting is of different tracer plugs in different regions of the tubular string and recording locations for each different tracer. 
     
     
         20 . The method as claimed in  claim 18  further including determining from where the flowed fluid emanated.
