Method and System for Treating A Subterranean Formation

Abstract

A method and apparatus to treat a subterranean formation comprising a wellbore including introducing a tool to a wellbore in a region of low permeability or damage, treating the region of low permeability or damage with a fluid, simultaneously measuring a fluid pressure drop and volume of fluid flow in a particular region, and moving the tool to another region. A method and apparatus to treat a subterranean formation comprising a wellbore including introducing to a wellbore a tool in a region of low permeability or damage, treating the region of low permeability or damage with a fluid, introducing a diversion agent, and moving the tool to another region wherein the fluid comprises a tracer.

         1 . A method to treat a subterranean formation comprising a wellbore, comprising:
 introducing a tool to a wellbore in a region of low permeability or damage;   treating the region of low permeability or damage with a fluid;   simultaneously measuring a fluid pressure drop and volume of fluid flow in a particular region;   and moving the tool to another region.   
     
     
         2 . The method of  claim 1 , further comprising calculating properties of the region of low permeability or damage using the fluid pressure drop and volume of fluid flow. 
     
     
         3 . The method of  claim 1 , wherein the treating the region of low permeability or damage comprises a matrix acid treatment, a hydraulic fracturing treatment, introducing proppant, stimulating the region, or a combination thereof. 
     
     
         4 . The method of  claim 1 , further comprising introducing a tracer with the fluid. 
     
     
         5 . The method of  claim 5 , further comprising repeating the treating and moving the tool steps. 
     
     
         6 . The method of  claim 1 , wherein the tool has dimensions to allow fluid flow through the wellbore. 
     
     
         7 . A method to treat a subterranean formation comprising a wellbore, comprising:
 introducing to a wellbore a tool in a region of low permeability or damage;   treating the region of low permeability or damage with a fluid;   introducing a diversion agent;   and moving the tool to another region   wherein the fluid comprises a tracer.   
     
     
         8 . The method of  claim 7 , wherein the diversion agent comprises a tracer. 
     
     
         9 . The method of  claim 7 , further comprising simultaneously measuring a fluid pressure drop and volume of fluid flow. 
     
     
         10 . The method of  claim 9 , further comprising calculating properties of the region of low permeability or damage using the fluid pressure drop and volume of fluid flow. 
     
     
         11 . The method of  claim 7 , wherein the treating the region of low permeability or damage comprises a matrix acid treatment, a hydraulic fracturing treatment, introducing proppant, stimulating the region, or a combination thereof. 
     
     
         12 . A method to treat a subterranean formation comprising a wellbore, comprising:
 introducing to a wellbore a tool in a region of low permeability or damage;   treating the region of low permeability or damage with a fluid;   introducing a diversion agent;   monitoring the fluid, wherein the fluid comprises a tracer; and   moving the tool to an additional region.   
     
     
         13 . The method of  claim 12 , further comprising evaluating the fluid. 
     
     
         14 . The method of  claim 13 , wherein evaluating the fluid comprises estimating the permeability of the region of low permeability or damage. 
     
     
         15 . The method of  claim 12 , wherein the monitoring comprises measuring the concentration of tracer. 
     
     
         16 . The method of  claim 15 , further comprising calculating properties of the region of low permeability or damage using the fluid pressure drop and volume of fluid flow. 
     
     
         17 . The method of  claim 12 , wherein the monitoring the fluid comprises measuring parameters to estimate diversion agent properties. 
     
     
         18 . The method of  claim 17 , wherein the diversion agent properties include effectiveness of the diversion agent.
