Interactive Interpretation of Water-Bottom Multiples , by Clement Kostov

Continuation of a reflection event through a water layer is approximated by updating the parameters --- zero-offset traveltime and root-mean-square velocity --- of a hyperbolic traveltime curve. The continuation process depends on a single parameter, the traveltime through the water layer. A scan over traveltimes through the water-layer is readily generated in an interactive computer program by moving the mouse up or down. To identify water-bottom multiples interactively, the operator chooses first a primary event and a traveltime through the water layer and then compares an overlay pattern of multiple reflections to the data.
