Systems and methods are provided to correct seismic data for the undesired effects caused by near surface velocity variations. In one embodiment, a method includes receiving travel time data for a near surface region and estimating an initial velocity model for the near surface region using the travel time data. The method can include updating the velocity model by performing an inversion iteration of including inversion of travel times to estimate slowness. The process can also include calculating at least one long-wavelength static for the near surface region. The long-wavelength statics may be used to correct for undesired effects caused by near surface velocity variations.

Certain implementations of a three-dimensional elastic frequency domain iterative solver for full waveform inversion can be implemented as a method in which frequency domain numerical simulation of elastic waves is performed in three-dimensional (3D) media.
