Abstract:
1. An apparatus for acquiring seismic data used in characterizing a subsurface formation, comprising: a) a sensor unit configured to be coupled to the earth's surface to sense seismic energy, the sensor unit configured to sense seismic energy imparted into the subsurface formation and to provide a signal indicative of seismic energy reflected from the subsurface formation and suitable for imaging the subsurface formation; b) an acquisition device co-located with the sensor unit and coupled thereto, the acquisition device being configured to receive the signal; c) a memory unit disposed in the acquisition device, the memory unit being configured to receive a location parameter when the acquisition device enters a wake state; and d) a communication device configured to provide direct wireless bi-directional communication between the acquisition device and a remotely-located central controller.
