This course provides a thorough overview of the methods of multi-component (3-C and 4-C) seismic exploration from basic petrophysical analysis and survey design through 3-D converted-wave migration. Numerous examples and case histories show the design, application, and use of multi-component surveys. Both 2-D and 3-D surveys and analysis will be discussed. Marine surveys (up to 4C-4D measurements) and analysis are highlighted. Supporting measurements as dipole sonic logs and 3-C VSP are also included. Field case interpretation exercises reinforce concepts introduced by the instructors.
