Inversion driven free surface multiple modelling using multi-order Green’s functions

We introduce an inversion-driven free surface multiple modelling scheme based on multi-order Green’s functions. The approach optionally combines surface related multiple modelling with source designature and receiver deghosting. We demonstrate the effectiveness of the approach for peg-leg multiple suppression as well as highlighting the benefits of combined receiver deghosting and demultiple. In addition we show how the use of multiples can provide uplift for cable interpolation.
