Abstract:
We introduce an effective iterative Least-Squares Wave-Equation Migration (LS-WEM) solution for broadband imaging. LeastSquares Migration (LSM) solutions are designed to produce images of the subsurface corrected for wavefield distortions caused by acquisition and propagation effects. They implicitly solve for the earth reflectivity by means of data residual reduction in an iterative fashion, which usually demands intensive computation.
