MERLIN®—Anisotropic Reverse Time Migration

MERLIN provides full-waveform two-way migration. This GPU- and CPU-based algorithm operates in both forward and backward (migration) modes to achieve startling results on average seismic data. MERLIN includes:
  • full waveform, isotropic, acoustic TTI, and full elastic imaging;
  • user selection of an optimized finite-difference stencil;
  • migration from topography;
  • precise amplitudes;
  • is parameterized using Thomsen notation: ε, δ, VNMO, φ, and θ.

MERLIN provides full waveform data synthesis and two-way migration. Merlin utilizes a user-selectable finite-difference stencil to compute variable density isotropic, acoustic TTI, or even full elastic synthetic seismic data. This module is the most accurate application in Marvel's arsenal since finite differences are the only approximations used in the implementation.

MERLIN provides the foundation for the most accurate illumination studies possible. Its full waveform capabilities assure high quality assessment of acquisition designs, and its efficiency ensures rapid turnaround. Merlin produces the most accurate amplitude volume used to extract horizon-based illumination maps you can find. Merlin is

  • insensitive to strong velocity variations;
  • less sensitive to velocity anomalies then Kirchhoff or other ray-based approaches;
  • capable of migration from topography;
  • ultra fast when run on NVIDIA GPUs;
