Dynamically Focused Gaussian Beams for Seismic Imaging

Figure 1

Computed common-shot data is shown for a shot point on the surface at a position of 40,000 ft. The receiver array is from 25,000 ft to 55,000 ft. Diffractions from 5 compact scatterers are shown each with a horizontal position of 40,000 ft and depths of 8,000, 12,000, 16,000, 20,000, and 24,000 ft.
