Rough-Sea Deghosting Using Vertical Particle Velocity Field Approximations

P086 ROUGH-SEA DEGHOSTING USING VERTICAL PARTICLE VELOCITY FIELD APPROXIMATIONS Abstract TAGE RØSTEN 1 LASSE AMUNDSEN 1 JOHAN ROBERTSSON 2 and ED KRAGH 3 1 Statoil Research Centre Trondheim Norway 2 WesternGeco Product Technology Centre Oslo Norway 3 Schlumberger Cambridge Research Cambridge United Kingdom Two related methods for receiver ghost correction that can be applied to towed streamer data in rough-sea environments are compared. The two methods called method I (see Robertsson and Kragh 2001) and method II use different approximations for the vertical component of the particle velocity. Both methods take advantage of dense spatial sampling distance and require that
