Abstract

Static correction has been a major challenge for seismic exploration particularly in geologically complex areas having boulder beds and mountains . Such areas are characterized by lateral velocity variation in the weathered zone . It has been observed from the first breaks of seismic monitor records showing distinct features of bending events of near offsets. Therefore, assuming equivalent medium with quadratic velocity variation in depth, an attempt has been made to derive proper static correction in order to apply on the seismic data acquired in Pasighat areas of Arunachal Pradesh.
