Apparatus for detecting geophysical energy
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.

a plurality of expansible section periodically disposed in-line in the fluid conduit, each expansible section being positioned between the production tubing and an associated receiver, the expansible sections being configured to expand in response to an increase of fluid pressure within said conduit, and when expanded, to press against the production tubing and the receivers and thereby cause the receivers to be moved from first positions to second positions; and
wherein the plurality of receivers are in signal communication with the signal transport device.
10. The apparatus of claim 9 , and further comprising a plurality of receiver contacting members and a plurality of production tubing contacting members, and wherein each receiver contacting member is supported between a corresponding receiver and a corresponding expansible section by way of the corresponding receiver, and wherein each production tubing contacting member is supported between a particular expansible section and the production tubing by way of the particular expansible section, and wherein the plurality of receiver contacting members and the plurality of production tubing contacting members are configured to maintain a substantially parallel linear alignment of the plurality of receivers and the plurality of expansible sections and the production tubing as the receivers are moved from the first positions to the second positions.
11. A method of deploying a receiver in a wellbore, compromising:
placing a production tubing in the wellbore;
placing a fluid conduit in the wellbore;
placing an expansible section in-line in the fluid conduit proximate the production tubing;
placing a receiver in the wellbore proximate the expansible section; and
increasing pressure of a fluid in the fluid conduit to cause the expansible section to expand and press against the production tubing and the receiver, to thereby urge the receiver from a first position to a second position.
12. The method of claim 11 , and further comprising restricting flow of fluid in the fluid conduit to cause the increase of pressure of the fluid in the fluid conduit.
13. The method of claim 11 , and further comprising conveying a chemical through the fluid conduit.
