Petrel Geophysics - Advanced

The course focuses on seismic interpretation workflows, techniques and best practices. This includes how to create and use different seismic attributes like Generalized Spectral Decomposition (GSD), Consistent Dip, Consistent Curvature, Directional Blending etc., different techniques of seismic attributes blending, attributes overlay in an interpretation window, Seismic Mixer (RGB/CMY - blending, Flip/Roll, Mask), attributes map generation, interactive cross-plotting of seismic attributes, populate seismic attributes in a 3D structured grid for analysis, optical stacking, conventional & contemporary methods of faults extraction, modelling while interpreting  and workflow editor setup for automatic attributes creation.

Furthermore, the course explains Multi-Z interpretation, snapping, create triangle mesh, interactive mesh editing, convert editable triangle mesh to multi-Z interpretation, workflows for geobody interpretation using different probes, populate a geobody into a 3D grid, chair cut displays of seismic attributes & modeled properties,  RGB blending of seismic attributes, perform Principal Component Analysis (PCA) of seismic attributes, Train estimation model using Neural Networks to find correlation in seismic attributes for interpretation purposes and lithology identification. It also discusses genetic inversion for volume attributes.
