Interface and method for transmitting information to and from a downhole tool

Abstract

A downhole interface is disclosed that is positionable between a downhole tool, such as a wireline tool, and a wired drill string. The downhole tool communicates with the downhole interface which in turn communicates with the wired drill string to transmit information to the Earth's surface. The interface provides signal and power communication to the downhole tool.

       2 . The system of  claim 1  wherein the downhole tool is a wireline tool. 
   
   
       3 . The system of  claim 2  wherein the wireline tool is an intervention tool. 
   
   
       4 . The system of  claim 3  wherein the intervention tool is positioned within a lower completion section. 
   
   
       5 . The system of  claim 4  wherein the lower completion section is incorporated into a portion of at least one of the plurality of wired drill pipes. 
   
   
       6 . The system of  claim 4  further comprising a plurality of sensors in communication with the intervention tool. 
   
   
       7 . The system of  claim 6  further comprising an upper completion section deployable on the plurality of wired drill pipes and communicatively coupled to the lower completion section. 
   
   
       8 . The system of  claim 3  wherein the downhole interface is directly coupled to the wireline tool and one of the plurality of wired drill pipes. 
   
   
       9 . The system of  claim 8  wherein the downhole interface includes electronics providing a power interface between one of the plurality of wired drill pipes and the wireline tool. 
   
   
       10 . A system for providing communication in a borehole comprising:
 a drill string comprising at least a portion of wired drill pipes communicatively coupled;   a downhole interface communicatively coupled to one of the wired drill pipes; and   a wireline tool communicatively coupled to the downhole interface, the wireline tool deployable on the drill string.   
   
   
       11 . The system of  claim 10  wherein the wireline tool is an intervention tool. 
   
   
       12 . The system of  claim 10  wherein information from the wireline tool is transmitted to the downhole interface and then transmitted to the wired drill pipes for transmission to the Earth's surface. 
   
   
       13 . The system of  claim 12  wherein the wireline tool is controlled based on an analysis of the information from the wireline tool. 
   
   
       14 . The system of  claim 11  wherein the intervention tool is positioned in a lower completion section. 
   
   
       15 . The system of  claim 11  wherein a portion of the drill string comprises the lower completion section. 
   
   
       16 . A method for transmitting information from a wellbore below the Earth's surface comprising:
 communicatively coupling a wireline tool to a downhole interface;   communicatively coupling the downhole interface between a drill string comprising a plurality of wired drill pipes and the downhole interface, the downhole interface directly coupled to the wireline tool and the plurality of wired drill pipes;   measuring a characteristic of the wellbore with the wireline tool;   transmitting a signal related to the characteristic of the wellbore to the downhole interface; and   transmitting the signal from the downhole interface to the plurality of wired drill pipes.   
   
   
       17 . The method of  claim 16  wherein the wireline tool is an intervention tool. 
   
   
       18 . The method of  claim 16  wherein at least a portion of the plurality of wired drill pipes comprise a lower completion section.
