Automated Geometry Extraction from 3D Seismic Data by Lateral Waveform Recognition

C015 AUTOMATED GEOMETRY EXTRACTION FROM 3D SEISMIC DATA BY LATERAL WAVEFORM RECOGNITION Summary 1 A novel method for extracting geometry primitives from seismic data is presented. All events in the 3D seismic cube is detected and combined into geometric primitives based on similarities in the local waveform. No assumptions of continuity in the geometric primitives are required which can therefore represent faulted reflectors. This facilitates quantification of the fault displacement. The accuracy with which the local waveform is represented is selectable implying that subtle lateral changes in the reflectivity can be detected and exploited. This characteristic enables analysis of stratigraphic
