ABSTRACT:
Methods of compressing sonic data acquired as the result of well logging procedures are disclosed. Samples of each digitized formation wave component are characterized as a vector. Eigenvectors based on the formation wave component vectors are obtained, and selected wave components are correlated to the eigenvectors to obtain scaler correlation factors. The eigenvectors and correlation factors together provide a compressed representation of the selected formation wave component, particularly since only a few eigenvectors and correlation factors are required to provide an excellent reconstruction of the formation wave component.
