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.

Cableless seismic sensors and methods for recharging

A system and method for performing a marine seismic survey of a subsurface. The method includes deploying under water, from a deploying vessel, an autonomous underwater vehicle (AUV); recording with seismic sensors located on the AUV seismic waves generated by an acoustic source array; instructing the AUV to surface at a certain depth relative to the water surface; recovering the AUV by bringing the AUV on a recovery vessel; and transferring recorded seismic data to the recovery vessel.

Deployment and recovery of autonomous underwater vehicles for seismic survey

A method for acquiring geophysical data includes connecting a power module comprising a data transfer port and a power transfer port to a geophysical data acquisition device to provide a geophysical sensing node and deploying the geophysical sensing node. While deployed, data is transferred from the geophysical data acquisition device to the power module via the data transfer port and power is transferred from the power module to the geophysical data acquisition device via the power transfer port. The method also includes retrieving the geophysical sensing node and replacing the power module with a newly charged power module to provide a newly charged geophysical sensing node, and deploying the newly charged geophysical sensing node. Corresponding systems are also disclosed herein.

Geophysical survey node rolling method and system

According to an embodiment, a seismic receiver device is described for use in a borehole surrounded by an ambient material, e.g., rock, mud, etc. The seismic receiver device includes a pressure wave measuring device which is configured to sense pressure changes associated with received seismic waves, a coating layer disposed on the pressure wave measuring device, and an outer layer disposed on the coating layer which is made of a material that is selected to have a bulk modulus number that is substantially similar to a bulk modulus number of the ambient medium. In this way, the acoustic impedance of the device is better matched to the ambient material so that more accurate seismic acquisition may be performed.
