oa Horizon Based Target Orientated Beam Demultiple with Examples from the North West Shelf, Australia

Beam Migration has specific advantages, in its speed and high signal-to-noise levels, which make it suitable for both depth velocity modelling and final imaging. One property of Beam Migration is that wavelets can, based upon a combination of criteria, be weighted down or excluded from reconstruction. It is possible to reject wavelets that match a multi-dimensional multiple model. This model is based upon a combination of interpretation, normal moveout and spatial & temporal location.

Data examples from the North West Shelf, Australia, illustrate the flexibility of this approach and demonstrate its effectiveness in the complex inter-bed multiple area of Browse Basin.
