Abstract

Interpreting seismic data requires inferences to be made from the geometry, character, and spatial association of seismic re-flections. Seismic attributes that highlight such associations are essential for understanding basin-fill histories. In this arti-cle, we describe two novel attributes obtained from an auto-matic full-volume-flattening algorithm and apply them to a synthetic seismic volume of experimental strata. The stratal convergence attribute colors reflections according to their de-gree of convergence, which is commonly high in areas where strata thin because of erosion or nondeposition. The instanta-neous isochron attribute measures thickness between reflec-tions and is therefore generally proportional to sediment accumulation rate. These attributes distinguish bounding sur-faces and depocenter migration in well-constrained experimental strata. By showing the diagnostic value of each attribute, our study motivates field-based applications of full-volume flat-tening and attribute co-rendering for seismic stratigraphie interpretation.
