OFFSHORE EAST COAST: MODEL-BASED WATER-LAYER DEMULTIPLE BREATHES NEW LIFE INTO OLD DATA
CSEG Recorder October 2014
Keith Wilkinson and Richard Bale
This CSEG Recorder article describes the recent development and application of a model-based water-layer demultiple technique. It discuss some application details such as the water-bottom Green’s function and the necessity of a two-step prediction to handle both shot-side and receiver-side multiples. This method is tested using a finite difference synthetic dataset and then applied to two different 2-D marine lines from offshore East Coast of Canada.
