WebbSummary Local slope, as one of the key attributes of locally coherent events, has been a hot research issue for decades in seismic data processing. However, the estimation of local slopes for intersecting events is still challenging. In this paper, we first detail the multimodality of coherency of intersecting events in the slope domain, and then … WebbComplex seismic trace attributes were introduced around 1970 as useful displays to help interpret seismic data in a qualitative way.
