As we rewrite the Previous HitseismicNext Hit Previous HitdataNext Hit Previous HitprocessingNext Hit and interpretation programs to account for the true vector nature of the Previous HitseismicNext Hit Previous HitdataNext Hit, we are able to extract more types of Previous HitdataNext Hit and see further into the background noise. Examples of the extra types of Previous HitdataNext Hit have been published by many authors: Amplitude vs. Offset (AVO) Technology and Shear Wave Splitting. Since others are covering the other types of Previous HitdataNext Hit such as splitting shear waves and AVO, this paper will discuss the enhanced ability to define and extract Previous HitseismicNext Hit signals using patented vector Previous HitprocessingNext Hit technology.

Previous HitSeismicNext Hit Previous HitprocessingNext Hit in a vector mode leads to the following conclusions: (1) Previous HitseismicNext Hit information (extractable by cross-correlation or semblance type analysis) is carried in the direction cosines not in either the vector or the component (i.e., vertical) amplitudes. (2) By vector bandpass filtering Previous HitseismicNext Hit Previous HitdataNext Hit, the signal-to-random-noise ratios can be improved by at least 12 db (a factor of four) over conventional scalar Previous HitprocessingTop.
