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 ).
