ABSTRACT:
A method for quantitatively measuring lateral continuity at a specified subsurface location from seismic data. The seismic data trace nearest to the specified location is designated as the reference trace. Next, all data traces falling within a specified distance from the reference trace are extracted from the data, and one or more statistics which measure the similarity between each trace and the reference trace are calculated. Only the portions of the traces falling within the target formation are considered. Preferably, the statistics should permit comparison of both the temporal and atemporal behaviors of the traces. The results are compared to objective significance tests to determine whether each trace is the same as or different from the reference trace.
