Elastic module, Seismic types of waves. Seismic reflection, Reflection coefficients. Time-depth conversion: (Synthetic seismograms, Check-shot, VSP) Seismic resolution, Primary and multiples events, CPM method. Seismic data acquisition of the 2-D and 3-D seismic (Energy Sources, Detectors, Seismic data processing (velocity determination, Frequency and filtering, diffraction and migration. PARTII: Basin Architecture Earth model, and Plate Tectonics Concept. Isosticy & subsidence. Salt Tectonics. Basin Types. Fore-arc basins Back-arc basins Foreland basins Pull-apart basin Relationship between basin architecture and associated structures. Case histories (Seismic examples on basins). PARTIII: Seismic Interpretation Depositional environments. Sedimentary supply & processes. Sediments Fairways. Well log Correlation. Salt Structures. Seismic Migration Fault Types and Interpretation. Seismic Maps (Time-structure, Isopach, Surface, Time, and Slice Maps) Seismic Facies Analysis (Clastics vs. Carbonate facies). Chrono-stratigraphy vs. Litho-stratigraphy Seismic response of the different structures. Case histories: o Arabian Gulf (Carbonate and salt) o Gulf of Mexico (Depositional environment of clastics and salt). Two Field Trips: 3-D Seismic Acquisition crew (around Haradh area, Ghawar Field) 3-D Seismic Data Processing (Exploration Building at Saudi Aramco) References: Asquith G., 1982, Basic well log analysis for geologists, American Association of Petroleum Geologists. 216 p.
