Abstract

A sensor configuration including a centralizer having a rib, a hollow defined within the rib, and a sensor positioned within the hollow. A borehole system including a borehole, a tubular string disposed within the borehole, a centralizer having a rib, and the rib defining a hollow, disposed upon the tubular string, a sensor within the hollow. A method for acquiring data in a borehole including running a sensor configuration as in any prior embodiment on a tubular string into a borehole, cementing the tubular string in the borehole, and sensing with the sensor configuration, a parameter in the borehole.

Claims

exact text as granted — not AI-modified
1 . A sensor configuration comprising
 a centralizer having a rib;   a hollow defined within the rib; and   a sensor positioned within the hollow.   
     
     
         2 . The sensor configuration as claimed in  claim 1  wherein the centralizer is a solid body centralizer. 
     
     
         3 . The sensor configuration as claimed in  claim 1  wherein the sensor is entirely contained within the hollow. 
     
     
         4 . The sensor configuration as claimed in  claim 1  wherein the sensor is sealed within the hollow. 
     
     
         5 . The sensor configuration as claimed in  claim 1  wherein the sensor is a cement integrity sensor. 
     
     
         6 . The sensor configuration as claimed in  claim 1  wherein the sensor is a temperature sensor. 
     
     
         7 . The sensor configuration as claimed in  claim 1  wherein the sensoris a pressure sensor. 
     
     
         8 . The sensor configuration as claimed in  claim 1  wherein the rib is more than one rib, at least more than one of the more than one ribs containing sensors. 
     
     
         9 . The sensor configuration as claimed in  claim 8  wherein the sensors are selected from the same type of sensor or different sensors for the more than one of the more than one rib. 
     
     
         10 . The sensor configuration as claimed in  claim 2  wherein the centralizer comprises a metallic material. 
     
     
         11 . The sensor configuration as claimed in  claim 2  wherein the centralizer comprises a polymeric material. 
     
     
         12 . A borehole system comprising:
 a borehole;   a tubular string disposed within the borehole;   a centralizer having a rib, and the rib defining a hollow, disposed upon the tubular string;   a sensor within the hollow.   
     
     
         13 . A method for acquiring data in a borehole comprising:
 running a sensor configuration as claimed in  claim 1  on a tubular string into a borehole;   cementing the tubular string in the borehole; and   sensing with the sensor configuration, a parameter in the borehole.   
     
     
         14 . The method as claimed in  claim 12  wherein the sensing is over time. 
     
     
         15 . The method as claimed in  claim 11  further including running another tool whose primary function is not sensor interrogation with an interrogator thereon. 
     
     
         16 . The method as claimed in  claim 12  wherein the tookis a drilling assembly. 
     
     
         17 . The method as claimed in  claim 12  wherein the tool is a completion string.
