Introduces 3-D seismic techniques used in exploration and reservoir delineation. Describes operations involved in 3-D surveys, including field work, processing and interpretation.
Presents a comprehensive look at 3-D techniques, including acquisition, processing and interpretation. Discusses acquisition methods and quality control for land and marine surveys. Addresses velocity analyses, trace binning, NMO and migration. Examines time slices, chair displays and other 3-D displays. Illustrates role and capabilities of the workstation in 3-D interpretation. 4-D Seismic, also known as time-lapse monitoring is intended to highlight the differences between successive vintages of 3-D seismic surveys that are caused by changes in reservoir properties due to production.
