Hybrid Stratigraphic Seismic Attribute for Multi-purposes

Seismic horizons correspond with isochrones, which group a set of points in (X, Y, Z) corresponding if possible to a same geological age, a same moment of deposit. These surfaces are then distorted and faulted by tectonic events, until obtaining the final surface picked by the interpreter. So each chosen picked horizon corresponds with a specific geological age. Each fault corresponds to a 3D surface that is a lateral discontinuity in this geological age.

Structural Layer Cube (SLC) gives a consistent pseudo-geological age for each sample in the seismic cube. By reading it, the interpreter is able to understand its relative position to the seismic horizons. Looking at this SLC cube allows following spatial organization of deposits in 3D at a very detailed level, and checking 3D consistency with key geological rules. Combined with well data, it can be used to create very detailed earth models for seismic modelling or a-priori models seismic inversions.
