Abstract (en)
Apparatus for transmitting data in a borehole (10) between a downhole tool installation including one or more tools (20) (for example downhole testing tools) and a surface installation (62), wherein the downhole tool installation is connected to the surface installation by means of a tubular conduit (such as a drill string or production tubing (14), the apparatus comprising - an acoustic modem (26) associated with each tool, the modem acting to convert tool signals such as electrical tool signals into acoustic signals; and - a hub (90) forming part of the downhole installation to which the tools and tubular conduit are connected and comprising an acoustic receiver (74) and an electromagnetic transmitter (80); wherein the acoustic modems operate to generate acoustic signals in the installation representative of the tool signals, the acoustic tool signal passing along the downhole installation to be received at the acoustic receiver of the hub, the received acoustic signals being used to operate the electromagnetic transmitter to transmit electromagnetic signals to the surface for reception at the surface installation.
