A method for determining surface consistent statics associated with recorded seismic trace signals is described comprising the steps of: (a) generating acoustic waves into a geological formation from acoustic wave sources; (b) recording arriving representations of acoustic waves generated from the sources at spaced receiver locations; (c) forming a common offset trace (COT) gather of recorded acoustic waves; (d) measuring the differences in arrival times of reflection signal components in the COT gathered traces; (e) normalizing the paths taken by the refraction signal components to the paths taken by the reflection signal components to correct for slant paths (angular displacements) between the refractions and reflection signal components; (f) measuring the differences in arrival times of the normalized refraction signal components in the COT gathered traces; (g) determining the source and receiver statics for the COT gathered traces; and (h) aligning the gathered traces in time by shifting each COT gathered trace by an amount corresponding to a determined source and receiver static associated therewith; and (i) determining the two way travel time from a datum to a reflection boundary.
