What is full-waveform inversion (FWI)?

Full-waveform inversion is a technique that extracts significantly more information from seismic data by processing every distortion a wave experiences, allowing scientists to reverse-engineer subsurface structures.

How is seismic imaging used for climate initiatives?

Advanced seismic imaging, like FWI, is crucial for identifying and monitoring rock formations suitable for carbon capture and storage, ensuring injected carbon dioxide remains safely contained.

What is distributed acoustic sensing (DAS)?

DAS uses underground optical fiber cables to measure vibrations, turning the cable into a string of sensors that provide a high-definition readout of subsurface composition and conditions.

Journey to Earth's Core: New Tech Unlocks Secrets

Jules Verne's 19th-century fantasy of exploring Earth's interior has become a scientific pursuit, driven by the need to understand substructures for energy and climate initiatives. Modern geoscientists use sophisticated methods to create detailed 3D images of the planet's interior.

Full-waveform inversion (FWI), developed from physicist Albert Tarantola's work, processes seismic data comprehensively. This technique reverse-engineers subsurface structures by comparing simulated wave reflections against real-world measurements, yielding unprecedented detail.
