P 072 Summary APPLICATION OF PRESTACK KIRCHHOFF MIGRATION TO VERTICAL CABLE SEISMIC DATA H.J. WANG 1 2 and X.-Y. LI 1 1 British Geological Survey West Mains Road Edinburgh EH9 3LA 2 University of Edinburgh Department of Geology and Geophysics The Vertical cable seismic (VCS) represents an alternative method to acquire 3-D seismic data by using vertical arrays of hydrophones instead of conventional horizontal arrays. Based on its unique geometry we develop a prestack Kirchhoff time migration algorithm to perform vertical cable seismic imaging on the common receiver gather. The modified traveltime equation is used in this technique and the
