SEISMIC SIGNAL PROCESSING METHOD AND APPARATUS FOR GENERATING CORRELATION SPECTRAL VOLUMES TO DETERMINE GEOLOGIC FEATURES

摘要

A seismic signal processing method (74) to analyse a set of seismic data (80)and determine a set of geologic characteristics of the earth formation (94)using a cross correlation technique with steps of a first data set with two ormore traces having known geological characteristics is cross correlated (88)with a second data set and generating and output record of correlationspectral volume with display and of the unknown geological characteristics ofthe second data set (92) substantially matches one ore more of the knowngeological characteristics of the first data set.
