Dynamically allocating different numbers of bits to windows of a series representing a seismic trace

摘要

To process seismic data, a set of data values representing a seismic trace is received, and amplitudes of data values associated with plural groups in the set are analyzed. Different numbers of bits are dynamically allocated to at least some of the groups of the set according to the analyzing.

1. A method of processing seismic data, comprising:
receiving, by a system having a processor, a set of data values representing a seismic trace; determining, by the system, maximum absolute amplitudes of data values in corresponding plural groups in the set, wherein the determining includes identifying, for at least one of the plural groups, the corresponding maximum absolute amplitude from among data values in the respective group; computing, by the system, an aggregate of the maximum absolute amplitudes to produce aggregate values; dynamically allocating, by the system, different numbers of bits to at least some of the groups of the set according to the determined maximum absolute amplitudes and the aggregate values; using the dynamically allocated numbers of bits to store data values in the corresponding groups: and identifying, by the system using the stored data values, a subterranean element in a subterranean structure.
