    Rock Physics and Statistical Rock Physics for Seismic Reservoir Characterization and Quantitative Interpretation

    This course covers fundamentals of Rock Physics and Statistical Rock Physics, ranging from basic laboratory and theoretical results to practical “recipes” that can be immediately applied in the field.  We will present qualitative and quantitative tools for understanding and predicting the effects of lithology, pore fluid types and saturation, stress and pore pressure, and temperature on seismic velocity. We will present case studies and strategies for quantitative seismic interpretation and, suggestions for more effectively employing seismic-to-rock properties transforms in reservoir characterization, with emphasis on seismic interpretation for lithology and subsurface fluid detection.
