Interactive Seismic Modeling
WesternGeco GeoSolutions prestack seismic modeling capabilities are comprised of integrated ray tracing and illumination software and workflows which deliver fast and accurate modeling.
At a user-specified location, the workflow can determine which horizon dip is illuminated and which horizon dip cannot be illuminated as well as the illumination strength of each dip component. Input requirements to the illumination calculation are simply a velocity model and the seismic acquisition geometry. There is no need for input horizons. Once the radar display for the location has been output (see the graphic above), the user can click on the radar display for interactive ray tracing in the image domain.
Using as input either a pure gridded velocity model, a horizon-based model, or a hybrid velocity model, the reflection or diffraction ray-tracing modeling capability provides users with a fast and integrated method of determining the energy and spatial distribution for a particular acquisition geometry. Coupled with the illumination spectrum, users can quickly determine which horizon dip is illuminated and which horizon dip cannot be illuminated. The functionality is geared to facilitating interpreters’ work processes: one click of the mouse button anywhere in the image volume will yield the reflection or diffraction rays.
Alternatively, for illumination studies, users can determine all illuminated structure at a particular spatial location.
