Per Avseth (Norwegian University of Science and Technology) discusses Rock Physics and Seismic Reservoir Prediction Constrained by Depositional and Burial Trends. Outline: 1. Rock physics background and motivation. 2. Using compactional depth trends to improve lithology and fluid classification from AVO - a demonstration from the Alvheim field, North Sea. 3. How burial history and associated variation in rock stiffness affects 4-D time shifts - An example from the Troll East field, North Sea. This is a compact version of Per Avseth's Distinguished Lecture Programme presentation.
