Dix inversion
WebABSTRACT Seismic sequences are stratigraphic units of relatively conformable seismic reflections. These units are intervals of similar sedimentation conditions, governed by sediment supply and relative sea level, and they are key elements in understanding the evolution of sedimentary basins. Conventional seismic sequence analyses typically rely … WebJan 29, 2024 · The Flying Dutchman, painting by Charles Temple Dix.

The accuracy of this model is critical for imaging techniques such as depth migration and inversion. Therefore, the reliability of seismic interpretation is strongly dependent on the accuracy of the derived model. Uncertainties in the velocity and depth …
WebMar 14, 2011 · The Dix inversion is conventionally formulated as a 1D inversion problem in the locations with picked rms velocities. Under the assumption that Dix inversion is … WebBlocky velocity inversion by hybrid norm Ali Ameen Almomin. Abstract Inverting a regularized Dix equation using the L2 norm produces smooth interval velocity models. To get a blocky interval velocity estimate that is more geologically reasonable, a regularized Dix inversion needs to be done using an L1-like norm.
WebOct 2, 2014 · Stacking velocity inversion sometimes may be substituted for Dix conversion to estimate interval velocities. Alternatively, depth conversion may be performed using vertical rays. This is acceptable only if lateral mispositioning because of lateral velocity variations is negligible (introduction to earth imaging in depth).
