WebJan 24, 2024 · Seismic inversion is a process to obtain the spatial structure and physical properties of underground rock formations using surface acquired seismic data, constrained by known geological laws and drilling and logging data. The principle of seismic inversion based on deep learning is to learn the mapping between seismic data and rock properties … Webfor these competing effects and accurately quantify seismic attenuation. We validate the approach using realistic simulations and apply it to real data sets at young (∼3 Myr) and older (∼70 Myr) locations in the Pacific Ocean. Our observations revise previous estimates of attenuation at the two locations, revealing high
