Volume visualization and automatic tracking in CFP-related processing

The Common Focal Point (CFP) technology involves the estimation of one-way travel time operators, describing the propagation effects from a selection of gridpoints at reflecting interfaces towards the surface locations. These operators can be obtained from the data without using any velocity depth model. These operators can be used in several data-driven processing steps: prestack redatuming, internal multiple removal and velocitydepth model estimation. In any of these applications, updating of many CFP gathers along one specific boundary plays a central role. To reduce user-interaction, 3D volume visualization and automatic tracking are used to get an optimum control on the process. © 2000 Society of Exploration Geophysicists.
