Anisotropic Raytracing in MARVEL®
The fully parallel dynamic raytracer module in MARVEL calculates traveltime maps in general TTI earth models. Consistency of local wavefront curvature and adaptive integration along rays ensures accuracy of both arrivals and amplitudes. You can choose from most energetic, minimum velocity, minimum distance or first arrival criteria to compute the optimum traveltime volume for the assumed geophysical objective. MARVEL's dynamic ray racer has been optimized over its seven years of production use. The anisotropic raytracer
- is used to synthesize common offset, common shot, and common horizon data sets;
- is used to apply demigration;
- shoots from an arbitrary location;
- facilitates migration from topography;
- can calculate thousands of rays in fractions of a second;
- is the foundation for Gaussian beam migration;
- is parameterized using Thomsen notation: ε, δ, VNMO, φ, and θ.
