Automated Structural Interpretation Through Classification of Seismic Horizons

Abstract

A novel method for extracting geometry primitives from seismic data is presented. All events in the 3D seismic cube will be detected and can be combined into geometric primitives based on similarities in the local wave form. No assumptions of continuity in the geometric primitives are required. The geometric primitives can therefore represent faulted horizons, which furthermore facilitates quantification of the fault displacement. The accuracy with which the local waveform can be represented is defined as a user input, implying that subtle lateral changes in the reflectivity can be detected and exploited. This characteristic enables analysis of stratigraphic variations along horizons.
