SUMMARY Recently two-way solutions of the wave equation such as RTM have become commercially available:these are suited for complex environments where both steep dips and multipathing are an issue. Shot-based oneway WE preSDM techniques assume that wavefields travel along the direction of extrapolation in one direction only - downwards for the source and
