Reverse Time Migration (SwRtm)
-
A wide variety of acquisitions scenarios: towed streamer, land, VSP, OBN/OBC and etc.
-
Output reflectivity image, impedance image, and velocity perturbation image
-
Classic quality control benchmarks
-
Full-band fidelity algorithm: strictly maintains the spectrum and phase of the input wavelet
-
Boundary conditions: absorbing conditions (no ghost, source ghost only, receiver ghost only, or both source and receiver ghost), free surface
-
Vectorized Fast Fourier Transform
-
MPI + multi-threading
Wave Equation Forward Modeling (SwMod)

Delayed Time Full Wave Inversion (DTRWI) ----- Patent Pending
-
Delayed time gather (DTCIG) in FWI process:
-
Is sensitive to velocity perturbation and easy to analyze the model quality
-
Measures velocity inaccuracy using only kinematic information
-
Can be complimentary to data domain QC for FWI when geology is complicated
-
-
DTFWI is an innovative and robust framework to invert complex velocity models using both diving wave and reflections, which
-
does not suffer from
-
cycle-skipping
-
amplitude discrepancies
-
sensitivity to source signature
-
dependence on low frequency
-
need for good initial model
-
-
provides a powerful volumetric QC
