Overthrust velocity model

WebTransverse isotropy with a tilted symmetry axis (TTI media) has been recognized as a common feature of shale formations in overthrust areas, such as the Canadian Foothills. Since TTI layers cause serious problems in conventional imaging, it is important to be able to reconstruct the velocity model suitable for anisotropic depth migration. Here, we … WebThe velocity-depth model comprises a shallow sequence with a relatively simple structure. ...
