Statics: from imaging to interpretation pitfalls and an efficient way to overcome them
The only purpose of static correction is to compensate for wave propagation heterogeneities in the near-surface. Significant progress has been made in seismic imaging and velocity model building, e.g. surface wave inversion, and one might think that problems related to statics were now behind us. In this paper, we will first describe key remaining statics-related issues, and then we will present, through a 2D seismic line case study, a reliable and efficient way to solve those issues. We will detail a statics method computation strongly supported by geological modelling for primary statics and geophysical tools for residual statics.
