QUALITY CONTROL OF 3D HORIZON AUTO-TRACKING IN SEISMIC VOLUME

摘要

Seismic interpretation includes obtaining a seismic volume of a subterranean formation of a field. Through the seismic volume based on a similarity criterion of seismic values in the set of seismic traces, an estimated horizon is generated based on a selected seed while maintaining tracking data tracking the generating of the estimated horizon. A first selection of a selected point in the estimated horizon is received, and, from the tracking data, an ancestral path from the selected point to the selected seed is extracted. A subset of the set of seismic traces is selected based on the subset comprising points along the ancestral path, and displayed, within a graphic window on a physical display, the subset of the set of seismic traces.

1. A method for seismic interpretation, comprising:
obtaining a seismic volume of a subterranean formation of a field, wherein the seismic volume comprises a set of seismic traces of the subterranean formation; generating, through the seismic volume based on a similarity criterion of seismic values in the set of seismic traces, an estimated horizon based on a selected seed while maintaining tracking data tracking the generating of the estimated horizon; receiving a first selection of a selected point in the estimated horizon; extracting, from the tracking data, an ancestral path from the selected point to the selected seed, wherein the ancestral path comprises a sequence of derived points that are recursively derived from the selected seed based on the similarity criterion; selecting a subset of the set of seismic traces based on the subset comprising points along the ancestral path; and displaying, within a graphic window on a physical display, the subset of the set of seismic traces, wherein the subset of the set of seismic traces is annotated with the ancestral path.
