WebImagine that you have a seismic survey which corresponds to the geometry and prop-agation velocity of Figures 1 and 2. What is the maximum angle of propagation that can be observed from a reflection point at two way travel time depth τ = 0.3s and horizontal position x = 640m? How about travel time depth τ = 0.6s and horizontal position x = 640m? WebRTM has a proven track record for generating final images and is increasingly used for refining structural boundaries during velocity model building.
