WebMar 27, 2024 · The delta curves will be used to build 3D delta models (see Delta Model) for anisotropic depth migration. In general, delta is calculated at the wells using the checkshot Vint and an initial (NMO) isotropic Vint field. There is an option to use the small delta approximation for this calculation if you want. cnc wood folding table project

WebA check-shot survey or a VSP provide a basic depth–time function that can be used to convert time seismic images into depth seismic images and/or to convert depth-indexed logs into time-indexed logs. The difference between a check shot and a VSP survey is that the check shot is limited to recording just enough data to provide a time–depth function.
