WebIt is based on prestack Kirchhoff time migration and can be applied to both 2-D and 3-D data. The method is divided into two steps, a gathering process that forms common scatterpoint (CSP) gathers, and an imaging process using a Kirchhoff migration performed independently on each CSP gather. 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 ...
