The common depth point stack

摘要: The Common Depth Point (CDP) Method is a seismic data acquisition and processing technique which transforms field recordings from surveys into pseudo-cross-sectional images of the earth's geologic layering beneath survey line. Such are primary geophysical analysis tools used by explorationists to pinpoint likely drilling locations for oil gas reservoirs. CDP has evolved an elementary enhancement concept in analog era 1950s highly sophisticated digital imaging parameter estimation 1980s. This paper reviews history method, its underlying mathematical-physical basis terms simple computer simulations reflection experiments. method illustrated with actual examples several provinces, closes discussion some limitations Stack possible future directions imagery.
