Abstract:
A wellbore seismic receiver system (10) is disclosed which includes a system housing adapted to traverse a wellbore (11) and a sensor housing adapted to be placed in contact with a wall of the wellbore. The sensor housing has at least one seismic sensor disposed therein. A compliant chamber couples the sensor housing (26) to the system housing (12), and a controllable source of pressurized gas is coupled to an interior of the chamber.
