Course Description:

This course introduces the fundamentals of seismic attributes, basic information about their theory, sensitivity to noise, and interpretational applications to detail structure and stratigraphy.

In the first step, volumetric estimates of dip and azimuth, coherence, curvature, and lateral changes in amplitude and/orenergy, commonly called geometric attributes, are discussed and detailed. In the next step volumetric curvature and reflector shape are discussed. Spectral decomposition   for structural and stratigraphic feature detailing is discussed in the next stage. Structure-oriented filtering and image enhancement are discussed and their impact on structural and stratigraphic interpretation  are presented.

Prestack geometric attributes are discussed in the next phase for detailing quantitative analysis of elastic properties and mechanical strength and fluid detection. In the interpretation phase of the course, attribute expression of structural deformation is investigated followed by attribute expression of clastic and carbonate depositional environments. In the final phase attribute expression of deepwater depositional environment and reservoir heterogeneity are addressed.
