Abstract
A method can include receiving seismic data that has an associated bandwidth; for a number of frequency bands, for a number of frequency bands, iteratively filtering and adjusting the seismic data by applying band-pass filters to extract information associated with each of the frequency bands where the adjusting the seismic data includes, after each iteration, subtracting extracted information from the seismic data prior to a subsequent iteration; balancing the extracted information to generate spectrally balanced seismic data; and outputting the spectrally balanced seismic data.
Claims20
A method (1500) comprising:
- receiving seismic data that comprises an associated bandwidth (1510);
- for a number of frequency bands, iteratively filtering and adjusting the seismic data by applying band-pass filters to extract information associated with each of the frequency bands wherein the adjusting the seismic data comprises, after each iteration, subtracting extracted information from the seismic data prior to a subsequent iteration (1520);
- balancing the extracted information to generate spectrally balanced seismic data (1530);
- and
- outputting the spectrally balanced seismic data (1540).
A system (250) comprising:
- a processor (256);
- memory operatively coupled to the processor (258);
- and
- processor-executable instructions (270) stored in the memory to instruct the system wherein the instructions comprise instructions to
- receive seismic data that comprises an associated bandwidth (1511);
- for a number of frequency bands, iteratively filter and adjust the seismic data by application of band-pass filters to extract information associated with each of the frequency bands wherein to adjust the seismic data comprises, after each iteration, to subtract extracted information from the seismic data prior to a subsequent iteration (1521);
- balance the extracted information to generate spectrally balanced seismic data (1531);
- and
- output the spectrally balanced seismic data (1541).
One or more computer-readable storage media comprising computer-executable instructions to instruct a computer wherein the instructions comprise instructions to
- receive seismic data that comprises an associated bandwidth (1511);
- for a number of frequency bands, iteratively filter and adjust the seismic data by application of band-pass filters to extract information associated with each of the frequency bands wherein to adjust the seismic data comprises, after each iteration, to subtract extracted information from the seismic data prior to a subsequent iteration (1521);
- balance the extracted information to generate spectrally balanced seismic data (1531);
- and
- output the spectrally balanced seismic data (1541).
