The choice of parameters is determined by objectives of the survey, available resources, and geologic locality. Some simple modeling and/or a walkaway noise survey are helpful in choice of field parameters. Filtering data …In this context, the common depth point (CDP) seismic data acquisition is a unique technique. A standard technique practiced all over the world, it achieves signal enhancement at the cost of noise, via a summation process of several traces reflected from the same subsurface depth point but with different offsets known as CDP folds.The same method is also called Common-Depth-Point (CDP). Neither of the two names exactly describes the method, so while both are equally invalid, CMP is usually preferred. The general idea of the method is to acquire a series of traces (gather) which reflect from the same common subsurface mid-point.The common-depth-point information is gathered for a plurality of incidence angles, (theta), of less than 20-30° such that assumptions concerning various elastic parameters, density, compressional-wave-velocity and shear-wave-velocity can be made which allow the application of linear fitting techniques to the gathered data.CMP. 1. n.
