Two-layer velocity models, which sum the vertical time in the weathering layer and the vertical time from base of weathering to datum, produce an initial basis for 3D seismic near-surface static corrections in Saudi Arabia. The thickness and velocity of the weathering layer are highly variable so the near-surface modeling is extended with delay times calculated by the plus-minus and the generalized reciprocal method (GRM) technique.
