PSEUDO LOGS TO IMPROVE STRATIGRAPHIC CORRELATION BETWEEN SEDIMENTARY BASINS

摘要

In the invention in order to improve the tie between depositionally equivalent beds relative to two or more basins detected within a multi dimensional seismic volume of interest, pseudo logs based on the average of attributes derived from seismic impedance where the compaction trend is not present are created for each basin. The mean is taken over all available azimuths, following the structural variations of introduced micro layers. The correlation between the pseudo log relative to each basin enable a more reliable interpretation between the different basins from which sound exploration decision can be made. Such a process can be successfully applied to seismic data acquired in deep water environment.
