Structural geosteering constrained multi-trace sparse reflectivity inversion based on mixed norms

Abstract Inversion technology is widely used in the seismic field for an image of the subsurface reflectivity or impedance structure, which is more consistent with geological characteristics. However, the unconstrained traditional inversion method is intrinsically subjected to multi-solution and spatial-instability and may distort seismic facies in real-world applications. To address these limitations, we design the mixed-norm constraints, comprised of a temporal Lp-norm (0
