These … WebFeb 10, 2024 · However, the calculation of dip-angle gathers in three-dimensional seismic data processing is expensive, making its application difficult (Bruin et al. 1990). In the two-dimensional (2D) dip-angle gathers, reflection events are represented as concave shapes, whereas others are considered as ‘noise’ in reflection imaging (Zhang & Zhang 2014 ).

There are three types of gathers: Type 1 (Regular offset) — Gathers that have regular offsets for every CMP (Type 1 = same, same). Type 2 (Irregular offset) — Gathers that have irregular offsets, but the same irregularity for every CMP (Type 2 = different, same).

WebFeb 22, 2011 · Abstract. I present two methods for constructing angle gathers in 3-D seismic imaging by downward extrapolation. Angles in angle gathers refer to the scattering angle at the reflector and provide a natural access to analyzing migration velocity and amplitudes. In the first method, angle gathers are extracted at each downward-continuation step ...
