NORSAR-3D

The NORSAR-3D Main Window

A new 3D model representation technique (the Open Ray Model) gives flexible modelling possibilities with minor restrictions on the model completeness. For example, it is possible to perform seismic ray tracing immediately in a preliminary or incomplete depth model, i.e. interfaces may have holes or other undefined areas.

The Wavefront construction technique, invented and developed at NORSAR, ensures that all calculated rays are consistent in the Open Ray Model. Rays traveling through the incomplete or inconsistent parts of the model are rejected.

Another advantage of NORSAR-3D is the ability to calculate very efficiently ray contributions for a large number of shot and receiver positions. This is particularly useful with respect to simulation of multi-streamer geometries (e.g. in survey planning or in illumination studies), or in the calculation of Green's functions to be used in, e.g. depth migration. In simulation of large surveys, a batch wavefront tracer makes it possible to do modelling simultaneously on all the computers in the network.

The NORSAR-3D Model Builder

NORSAR-3D modelling software is modular in design, allowing NORSAR to tailor the package to your needs. Modules can be bolted onto the NORSAR-3D platform creating a flexible and dynamic software product.
