Advanced materials gun and logging bots for deep saturation measurement

Abstract

A well bore logging tool for measuring a pore fluid property of a hydrocarbon reservoir that may include, a tool housing, a vessel containing a tracer, a launcher attached to the vessel that may be configured to inject a tracer into the hydrocarbon reservoir. The well bore logging too may further include a retrieval device configured to extract at least a portion of the tracer from the hydrocarbon reservoir. The well bore logging too may further include a storage canister may be configured to store a portion of the tracer extracted from the hydrocarbon reservoir, and a scanning device may be configured to read a value of at least one fluid saturation property detected by the tracer. The vessel, launcher, retrieval device, storage canister, and scanning device may be enclosed in a tool housing.

         15 . A method for making a measurement of a pore fluid property of a hydrocarbon reservoir, comprising:
 inserting a logging tool into a well bore traversing the hydrocarbon reservoir;   injecting a tracer into the hydrocarbon reservoir;   extracting at least a portion of the tracer from the hydrocarbon reservoir;   storing the portion of the tracer extracted from the hydrocarbon reservoir;   scanning a value of a fluid saturation property detected by the tracer.   
     
     
         16 . The method of  claim 15 , further comprising:
 deploying a retractable hydraulic isolation device to hydraulically isolate a first segment of the well bore from a first segment of the well bore.   
     
     
         17 . The method of  claim 15 , further comprising:
 removing the logging tool from the well bore; and analyzing the portion of the tracer extracted from the hydrocarbon reservoir to determine a value of a fluid saturation property.   
     
     
         18 . The method of  claim 15 :
 wherein the tracer comprises a chemical reactive to a pore fluid property of the hydrocarbon reservoir.   
     
     
         19 . The method of  claim 15 :
 wherein the tracer contains a plurality of nano-scale sized sensors sensitive to a pore fluid property of the hydrocarbon reservoir.   
     
     
         20 . The method of  claim 18 :
 wherein the property is a phase of the pore fluid of a hydrocarbon reservoir.
