Wireless activation of wellbore tools

Abstract

Systems and methods are disclosed for a well tool. The well tool system includes a receiving tool disposed in a wellbore tubular. The receiving tool is configured to transition from an inactive state to an active state in response to a triggering signal. The well tool system further includes a transmitting tool at a surface and proximate to the receiving tool. The transmitting tool is configured to wirelessly transmit the triggering signal to the receiving tool.

What is claimed is: 
     
         1 . A well tool system comprising:
 a receiving tool disposed in a wellbore tubular, the receiving tool configured to transition from an inactive state to an active state in response to a triggering signal; and   a transmitting tool at a surface and proximate to the receiving tool, the transmitting tool configured to wirelessly transmit the triggering signal to the receiving tool.   
     
     
         2 . The system of  claim 1 , wherein:
 the receiving tool comprises a power supply and an electrical load; and   in the inactive state, a circuit is incomplete and current flow between the power supply and the electrical load is disallowed.   
     
     
         3 . The system of  claim 2 , wherein in the active state, the circuit is complete and current flow between the power supply and the electrical load is allowed. 
     
     
         4 . The system of  claim 1 , further comprising the receiving tool configured to transmit a signal indicating a status of the receiving tool. 
     
     
         5 . The system of  claim 1 , further comprising the receiving tool configured to transition from the active state to the inactive state in response to a second triggering signal. 
     
     
         6 . The system of  claim 1 , further comprising the receiving tool configured to transition from the active state to the inactive state in response to a timer. 
     
     
         7 . The system of  claim 1 , further comprising the receiving tool configured to transition from the active state to the inactive state in response to a temperature. 
     
     
         8 . The system of  claim 1 , wherein the receiving tool includes a switching system. 
     
     
         9 . The system of  claim 1 , wherein the triggering signal is electromagnetic. 
     
     
         10 . The system of  claim 9 , wherein the transmitting tool includes a magnetically permeable core. 
     
     
         11 . A tool method comprising:
 positioning a receiving tool within a wellbore tubular;   positioning a transmitting tool at a surface and proximate to the receiving tool;   transmitting a triggering signal from the transmitting tool to the receiving tool; and   transitioning the receiving tool from an inactive state to an active state in response to the triggering signal.   
     
     
         12 . The method of  claim 11 , wherein the receiving tool comprises a power supply and an electrical load; and
 wherein in the inactive state, a circuit is incomplete and current flow between the power supply and the electrical load is disallowed.   
     
     
         13 . The method of  claim 12 , wherein in the active state, the circuit is complete and current flow between the power supply and the electrical load is allowed. 
     
     
         14 . The method of  claim 11 , further comprising transmitting a signal from the receiving tool indicating a status of the receiving tool. 
     
     
         15 . The method of  claim 11 , further comprising transitioning the receiving tool from the active state to the inactive state in response to a second triggering signal. 
     
     
         16 . The method of  claim 11 , further comprising transitioning the receiving tool from the active state to the inactive state in response to a timer. 
     
     
         17 . The method of  claim 11 , further comprising transitioning the receiving tool from the active state to the inactive state in response to a temperature. 
     
     
         18 . The method of  claim 11 , wherein the receiving tool includes a switching system. 
     
     
         19 . A well tool system comprising:
 a receiving tool disposed in a housing, the receiving tool configured to transition from an inactive state to an active state in response to a triggering signal; and   a transmitting tool at a surface and proximate to the receiving tool, the transmitting tool configured to wirelessly transmit the triggering signal to the receiving tool.   
     
     
         20 . The well tool system of  claim 19 , further comprising lowering the receiving tool into a subterranean wellbore.
