Migration of surface-related multiples: tests on the Sigsbee2B dataset
We present a theory to generate pseudo-primary shot gathers from multiple and primary reflections by performing a surface-consistent cross-correlation. The estimated pseudoprimaries exhibit the same kinematics as the original dataset with few transformation artifacts. We demonstrate that pseudo-primaries can accurately estimate missing traces as long as the gaps are within the acquisition sprea...
متن کامل3D wave-equation interferometric migration of VSP multiples
For VSP data, interferometric migration of free-surface multiples has two significant advantages over standard VSP migration: 1). a significantly larger imaging area than that of conventional migration of VSP primaries, and 2). less sensitivity to velocity and static errors than conventional migration of VSP multiples. In this report we validate these claims by applying wave-equation interferom...
متن کاملInterferometric imaging of multiples in an RTM approach
It is well known that reverse-time migration is capable of correctly imaging multiply scattered energy. To do this, one of the interfaces from which the waves scatter must be included in the background velocity model. In a one-way framework this requirement is avoided by iteratively forming images of higher-order scattered waves. These techniques use an image made with singly scattered waves to...
متن کاملIncorporating free-surface multiples in Marchenko imaging
Imagine placing a receiver at any location in the Earth and recording the response at that location to sources on the surface. In such a world, we could place receivers around our reservoir to better image the reservoir and understand its properties. Realistically, this is not a feasible approach for understanding the subsurface. Here, we present an alternative and realizable approach to obtain...
متن کاملComputerized interferometric surface measurements [Invited].
The addition of electronics, computers, and software to interferometry has enabled enormous improvements in optical metrology. This paper discusses four areas in which computerized interferometric measurement improvements have been made in the measurement of surface shape and surface roughness: (a) The use of computer-generated holograms for the testing of aspheric optics, (b) phase-shifting in...
