Abstract:
The present invention provides an adaptive filtering method for substantially eliminating ground roll noise encountered during seismic data acquisition. An apparatus for acquiring seismic data is provided that includes an adaptive filtering circuit coupled to a multi-axis sensor device.
Abstract:
The present invention provides a method and apparatus of acquiring and processing seismic data. One or more controllers are each coupled to seismic sensors and to each other to form a network of data acquisition units. A main controller is coupled to a crossline unit via a cable comprising a synchronizing conductor and one or more power/data conductors. Commands and data are packaged such that multiple routings are possible without affecting final calculations. Each crossline unit is capable of accepting a fiber optic input, a wire input or a combination.
