Creating a virtual source inside a medium from reflection data: heuristic derivation and stationaryphase analysis
S U M M A R Y With seismic interferometry a virtual source can be created inside a medium, assuming a receiver is present at the position of the virtual source. Here we discuss a method that creates a virtual source inside a medium from reflection data, without needing a receiver inside the medium. Apart from the reflection data, an estimate of the direct arrivals is required. However, no expli...

متن کاملCreating a virtual source inside a medium from reflection data with internal multiples: a stationary-phase analysis
Seismic interferometry allows one to create a virtual source inside a medium, assuming a receiver is present at the position of the virtual source. We discuss a method that creates a virtual source inside a medium from reflection data measured at the surface, without needing a receiver inside the medium and, hence, going beyond seismic interferometry. In addition to the reflection data, an esti...
متن کاملCreating Virtual Sources Inside an Unknown Medium from Reflection Data - A New Approach to Internal Multiple Elimination
It has recently been shown that the response to a virtual source in the subsurface can be derived from reflection data at the surface and an estimate of the direct arrivals between the virtual source and the surface. Hence, unlike for seismic interferometry, no receivers are needed inside the medium. This new method recovers the complete wavefield of a virtual source, including all internal mul...
متن کاملFocusing inside an unknown medium using reflection data with internal multiples: numerical examples for a laterally-varying velocity model, spatially-extended virtual source, and inaccurate direct arrivals
Seismic interferometry is a technique that allows one to reconstruct the full response from a virtual source inside a medium, assuming a receiver is present at the virtual source location. We describe a method that creates a virtual source inside a medium from reflection data measured at the surface, without needing a receiver inside the medium and, hence, presenting an advantage over seismic i...
