Abstract:
1. A method for operating a downhole tool comprising steps of: providing a conduit having a bore for passage of fluid therethrough, the conduit comprising at least one reader, wherein the at least one reader has a bore for the passage of fluid therethrough, the at least one reader including a conductor coiled around a substantially cylindrical liner, the at least one reader is on an inner surface of the conduit so as to be exposed to the bore of the conduit, the liner being substantially non-conducting, wherein the at least one reader is adapted to read data, the conduit including an electronics pack adapted to process the data read by the at least one reader, the electronics pack is housed within an internal recess in a wall of the conduit; providing a coupling between the electronics pack in the internal recess and the at least one reader to transmit the data from the at least one reader to the electronics pack in the internal recess, wherein an inner diameter of the bore of the at least one reader is no narrower than an inner diameter of the bore of the conduit; coupling the downhole tool to the conduit and making a coupling between the downhole tool and the electronics pack in the internal recess; providing a tag containing first data; moving the tag within the conduit and at least partially through the bore of the at least one reader, such that the at least one reader reads the first data from the tag when the tag is within the bore of the at least one reader; transmitting the first data from the at least one reader to the electronics pack in the internal recess through the coupling between the at least one reader and the electronics pack; processing the first data read from the tag in the electronics pack; generating an instruction corresponding to the processed first data, and passing the instruction from the electronics pack to the downhole tool through the coupling between the electronics pack in the internal recess and the downhole tool to operate the downhole tool.
