Sigbee velocity model
WebMar 12, 2024 · Then, a new imaging condition based on the down- and upgoing wave fields and a new weighting function are proposed to suppress RTM artifacts. The proposed imaging condition can suppress artifacts for each reflection angle independently. Finally, the proposed RTM procedure is tested using BP and Sigsbee velocity models. WebThe more useful the prior information (e.g., locations and shapes of features) included in the starting model is, the better the velocity model inverted by CNN-domain FWI will be. Figure 2 compares the velocity model inverted by conventional and CNN-domain FWI using the Sigsbee velocity model. Figure 2. (Figure 8 from Wu and McMechan.)
