| - | ### Why SAIG now? | + | ==== Why SAIG now?===== |
| - | The seismic industry is undergoing a significant transition. Acquisition systems are becoming larger and denser, while at the same time economic constraints are driving interest in sparse acquisition. Land datasets remain difficult to process and invert. CCS is creating new requirements for repeatable and cost-effective monitoring. DAS is producing new types of large-scale wavefield data. Machine learning is rapidly entering seismic processing, although robust integration with wave physics and inverse theory remains an open problem. | + | The seismic industry is undergoing a significant transition.
