ABSTRACT:
An apparatus and method for improving seismic resolution involving the application of scaling factors to seismic data which compensate for amplitude decay as a function of time, frequency and source-to-receiver distance (position). Each seismic trace associated with a common source-to-receiver distance is first separated into a plurality of frequency band-limited component traces. A time-variant amplitude scale factor (or its equivalent) is generated for each component trace. These scale factors are then applied to the component trace thus compensating for amplitude decay of the component trace. Upon recombination of the component traces a multidimensional amplitude scaled (MIDAS) seismic trace is recovered. The apparatus and method are particularly useful in creating a high-frequency extension of the frequency bandwidth resulting in improved resolution upon further processing or display. The method can be implemented as part of the field procedure or during subsequent computer processing.
