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.
