When one or more strongly reflecting interfaces exist in the sedimentary column, multiples from these reflectors start to build up and tend to mask the primary events. For example, in marine exploration, the water layer represents a nonattenuating medium bounded by two strongly reflecting interfaces, so it represents an energy trap. A seismic pulse generated in this energy trap will be reflected successively between the two interfaces. Those water reverberations will obscure reflections arriving from deeper horizons below the water layer. On land, a deep limestone layer bounded by strongly reflecting interfaces also can produce multiple reflections, which then interfere with primary reflections.
