What is XWI?
The XWITM toolkit extends conventional FWI by:
- Reformulating the objective function to avert cycle skipping without low frequencies in the field data (AWITM)
- Applying regularization to the model update direction for incorporating geological constraints (ATV)
- Alternating between long-wavelength and short-wavelength model updates for deeper penetration (RWI)
Adaptive Waveform Inversion is a patented variation of the FWI objective function which enables global minimum convergence from distant initial models
Why use XWITM on the Cloud?
- Register for the S-Cube AWS SaaS cluster and access a managed compute environment built for full waveform inversion
- Upload your existing job directories directly to the cloud virtual cluster with a few commands
- View the computational load per shot and select the number of shots, number of shots per instance and number of iterations of your job
- Always deploy the latest installations of XWITM
- Monitor and QC the live job on a dashboard accessed via a URL
