Automatic 3D seismic interpretation of horizons and sequence boundaries guided by seismic flowlines

With the use of seismic flowlines as a guide, we here present a workflow for automatic identification and 3D extraction of prominent seismic horizons and sequence boundaries. Seismic flowlines represent trajectories extracted from the local dip across the seismic volume. These seismic flowlines highlight apparent unconformities as they often appear as areas of convergence from the sequence above and the sequence below. This makes seismic flowlines suitable for identifying and mapping sequence boundaries. In addition, by combining seismic flowlines, which provides spatial relationship and first-order geometries, together with a series of seismic attributes. We are able to identify and map prominent reflectors in 3D. With this work we aim towards a framework for automatic interpretation that both identifies and extracts prominent reflections and sequence boundaries in 3D, informed by the seismic data itself, and without the need for extensive manual input.
