Translations:Instantaneous attributes - book/18/en

Apparent polarity is the polarity of the real trace at the instantaneous amplitude peak. In other words, apparent polarity is defined as the sign of $x_{n}$ when $A_{n}$ has a local maximum. Apparent polarity can help interpreters to identify gas accumulations. Lateral variations in all these displays can help to localize stratigraphic changes. Seismic traces representing wave motion can be transformed into corresponding traces representing a particular set of attributes, which then are available for further analysis.
