ABSTRACT:
A method of determining and analyzing spatial changes in the earth's subsurface. The method includes obtaining seismic attribute data as a 3D data volume and obtaining corresponding 3D dip and azimuth as a 3D volume and obtain corresponding 3D reliability volumes or 3D censor volumes which are representative of portions of the volume within in which a reliable dip and azimuth can be determined. A focused subvolume of interest within the 3D data volume is additionally selected. An average for the plurality of vector dips is computed and a flat spot direction vector for each structural dip and a flat spot direction vector dip magnitude is determined. Sequences of distances from each reliability location is defined and interpolated onto the direction of the flat pot direction vector. The sequences of interpolated seismic attribute data is summed and the summed sequences of interpolated seismic attributed data values are stored.
