Summary:
P022 Wave-Equation Prediction of Multiples – Different Strategies for Different Conditions D. Lokshtanov* (Hydro Oil & Energy) M. Denisov (GeoTechSystem Ltd) & E. Kurin (GEOLAB Ltd) SUMMARY SRME is the method of preference for data from areas with deep sea-floor especially when a thick package of strong reflectors is present below the sea-floor. To reconstruct missing traces required by 3D SRME prediction we use a repositioning of traces based on 3D hyperbolic moveout assumption. We use wave-equation (WE) approach when several orders of multiples are involved. WE approach is especially efficient when the main free-surface multiples are just ‘pure’ water-layer
