Method for attenuating multiples in CDP data gathers
WebCommon Depth Point The collection of seismic traces that correspond to a particular midpoint is called a Common Midpoint (CMP) gather. In older literature, this collection of traces is referred to as a Common Depth Point (CDP) gather. the CDP method is used to enhance the signal to noise ratio. This setup is variously called ... WebThe common-depth-point gather is conducted at angles of offset of less than 20-30 degrees 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. hunting the elements quizlet
