Full Waveform Inversion Around the World

An accurate earth model is key to any successful depth imaging project. FWI is an advanced velocity model building process that uses the full two-way wave equation and overcomes the limitations of existing methods that use a ray-tracing approach to distribute velocity errors within the model. Full-waveform inversion (FWI) has long been considered by the industry to be the next logical step in deriving detailed velocity models. The availability of low-frequency, long-offset data sets and increased compute power has now allowed FWI to become the preferred method for building detailed velocity models. In this presentation, we will show examples of imaging improvements obtained with FWI velocity models from different geological environments around the world
