WebOct 13, 2024 · We propose a multi-channel dynamic matching fullwaveform inversion (DMFWI) for a high-resolution velocity-model update, which focuses on solving kinematic difference between input data and synthetic data. With the data residual calculated in localized windows in time and space, DMFWI provides a robust velocity-model update … WebFeb 1, 2024 · Dynamic matching FWI (DMFWI) is a newly developed algorithm that solves an inversion problem that maximizes the cross correlation of two dynamically matched data sets — one recorded and the other synthetic. Dynamic matching of the two data sets de-emphasizes the amplitude impact, which allows the algorithm to focus on minimizing their ...

WebA proprietary dynamic warping correction avoids traditional cycle-skipping challenges, and the method does not depend upon an accurate starting model of velocity or any prior model of density. The PGS FWI solution is also extendable for multi-parameter updating, so that vertical velocity and epsilon are updated, and delta is fixed. WebMar 1, 2024 · Incorporating full-waveform inversion (FWI) in the velocity model building workflow for land surveys offers benefits not achieved with traditional model building tools, but it also brings difficulties. We have developed an effective model building workflow for land seismic data that incorporates dynamic matching FWI (DMFWI).
WebSummary We outline the evolution of a velocity model building workflow incorporating Dynamic Matching Full Waveform Inversion and multi-azimuth tomography for dense, long offset Ocean Bottom Node data in the Norwegian North Sea and evaluate the improvements this high-resolution velocity model brings to the final migrated image. Event positioning, … WebSummary In shallow water environments where usable offsets are limited, Full Waveform Inversion (FWI) has become a tool-of-choice to generate high-resolution velocity updates. Traditional approaches such as refraction and reflection traveltime tomography can struggle with capturing sharp lateral and vertical velocity variations responsible for structural …
