Abstract
A seismic data acquisition system includes a recording unit to record acquired seismic data and ground equipment containing surface units and wireless field digitizer units. Each surface unit is in communication with the recording unit and contains a first wireless communication module and a power supply mechanism transmitter coil. Each wireless field digitizing unit includes a seismic sensor unit, a second wireless communication module in communication with the seismic sensor unit and one of the first wireless communication modules to exchange digital data between the first and second wireless communication modules and a power supply mechanism receiver coil. The power supply mechanism receiver coil is magnetically coupled to the power supply mechanism transmitter coil in one of the surface units to transmit electrical energy wirelessly from the surface unit to the wireless field digitizer.
