METHODS AND APPARATUS FOR ANALYZING SEISMIC DATA

The invention provides methods and systems for analyzing seismic data. In one method, a set of three-dimensional seismic signal traces are provided. A reference of one of the traces is compared with at least two neighboring traces to find a neighbor trace with the least or most similarity to the reference trace. This neighbor trace is defined as a target trace. The reference trace is then compared with the target trace to produce a comparison value which is saved for later output or display.
