ABSTRACT:
One embodiment of the invention provides for an apparatus for detecting geophysical energy. The apparatus includes a receiver configured to receive geophysical energy and to convert the geophysical energy into a signal. The apparatus further includes a signal transport device configured to accept the signal and relay the signal to a remote location. The apparatus also includes a fluid conduit configured to contain a pressurized fluid, a production tubing, and an expansible section disposed inline in the fluid conduit. The expansible section is positioned between the production tubing and the receiver, and is configured to expand in response to an increase of fluid pressure within said conduit. When expanded, the expansible section presses against the production tubing and the receiver and thereby causes the receiver to be moved from a first position to a second position.
