Anisotropy
The development of a velocity field to optimally image seismic data with Pre Stack Depth Migration often results in a velocity which does not tie the vertical velocity derived at a well. This is due in large part to anisotropic effects in the overburden. Fairfield addresses this problem with its combination of anisotropic model building and anisotropic depth migration algorithms. The model building includes a patented method for calibrating seismically derived velocity models with existing well information followed by three parameter velocity analyses which scans for v0, and the Thomsen parameters delta and epsilon. We can use the anisotropic model to migrate using our Kirchhoff, wave equation shot migration, and reverse time migration algorithms.
