A seismic processing method to solve an eikonal equation to determine a travel time (t) of a sound wave between a seismic source at a first set of coordinates (x2,y2, z2) and a point underground at a second set of coordinates (x,y,z), comprising determining a distance between the seismic source and the point underground; obtaining a propagation time between the seismic source and the point underground; calculating a velocity variable (v) as a ration of the distance between the seismic source and the underground point divided by the propagation time between the seismic source and the point underground; and extrapolating on the velocity variable to obtain a travel time. |
