Real-time methods of tracking fluids

Abstract

A method of tracking an intelligent fluid in a well bore, comprising: providing an intelligent fluid; introducing the intelligent fluid into the well bore; sensing one or more well bore characteristics with the intelligent fluid; and wirelessly relaying data on the one or more well characteristics to the surface.

What is claimed is: 
     
         1 . A method of tracking an intelligent fluid in a well bore, comprising:
 providing an intelligent fluid;   introducing the intelligent fluid into the well bore;   sensing one or more well bore characteristics with the intelligent fluid; and   wirelessly relaying data on the one or more well characteristics to the surface.   
     
     
         2 . The method of  claim 1 , wherein the intelligent fluid comprises a well fluid and a sensor. 
     
     
         3 . The method of  claim 2 , wherein the well fluid comprises a cement, a cement spacer, a drilling mud, a completion fluid, a fracturing fluid, an acidizing fluid, a treatment fluid, or a chemical wash. 
     
     
         4 . The method of  claim 2 , wherein the sensor comprises a micro or nano sensor. 
     
     
         5 . The method of  claim 2 , wherein the sensor has an internal power source. 
     
     
         6 . The method of  claim 2 , wherein the sensor has an external power source. 
     
     
         7 . The method of  claim 1 , wherein the intelligent fluid has tacking capability. 
     
     
         8 . The method of  claim 1 , further comprising using the data for real-time data collection. 
     
     
         9 . A method of tracking a fluid in a well bore, comprising:
 providing a fluid;   introducing the fluid into the well bore;   introducing an intelligent wiper plug into the wellbore;   sensing one or more well bore characteristics with the intelligent wiper plug; and   wirelessly relaying data on the one or more well characteristics to the surface.   
     
     
         10 . The method of  claim 2 , wherein the fluid comprises an intelligent fluid. 
     
     
         11 . The method of  claim 3 , further comprising sensing one or more well bore characteristics with the intelligent fluid. 
     
     
         12 . A method of tracking fluid in a well bore, comprising:
 providing a fluid;   introducing the fluid into the well bore;   sensing one or more well bore characteristics with a sensor device disposed in the well bore; and   relaying data on the one or more well characteristics to the surface.   
     
     
         13 . The method of  claim 7 , wherein the sensor comprises an intelligent centralizer. 
     
     
         14 . The method of  claim 7 , wherein the sensor comprises an intelligent coupling.
