Abstract

OCO rays are lines associated with trajectories described by image points in a simulated common-offset section when several velocity fields are used for offset continuation (OCO) transformation. We present a methodology which makes use of OCO rays to find RMS velocity field using only two common-offset sections, which are referred as take-off and target sections, respectively. The main idea of this approach consists of looking for the best correlation between a selected reflection event in the take-off section and the corresponding one in the target section, being the search carried out along the appropriated OCO rays. We successfully apply the methodology in a deep water field dataset obtaining a geologically consistent time interval velocity model.
