  • Method for determining horizontal geophone orientation in ocean bottom cables
    Patent number: 6205403
    Abstract: Method is provided for determining the orientation or horizontal geophones used in marine seismic surveying. First-arrival signals are processed by rotating a coordinate system mathematically until the signal from the transverse receiver has minimum energy. The amount of rotation is used to calculate, from the known azimuth from the source, any misalignment of the horizontal geophone as the receiver is placed on the ocean bottom.
