AI-Enhanced Velocity Model Building for Subsurface Imaging

Published:Dec 29, 2025 11:12
1 min read
ArXiv

Analysis

This paper introduces a novel deep learning framework to improve velocity model building, a critical step in subsurface imaging. It leverages generative models and neural operators to overcome the computational limitations of traditional methods. The approach uses a neural operator to simulate the forward process (modeling and migration) and a generative model as a regularizer to enhance the resolution and quality of the velocity models. The use of generative models to regularize the solution space is a key innovation, potentially leading to more accurate and efficient subsurface imaging.
Reference

“The proposed framework combines generative models with neural operators to obtain high resolution velocity models efficiently.”

Differentiable Inverse Modeling with Physics-Constrained Latent Diffusion for Subsurface Parameter Fields

Published:Dec 27, 2025 01:01
1 min read
ArXiv

Analysis

This paper introduces a novel method, LD-DIM, for solving inverse problems in subsurface modeling. It leverages latent diffusion models and differentiable numerical solvers to reconstruct heterogeneous parameter fields, improving numerical stability and accuracy compared to existing methods like PINNs and VAEs. The focus on a low-dimensional latent space and adjoint-based gradients is key to its performance.
Reference

“LD-DIM achieves consistently improved numerical stability and reconstruction accuracy of both parameter fields and corresponding PDE solutions compared with physics-informed neural networks (PINNs) and physics-embedded variational autoencoder (VAE) baselines, while maintaining sharp discontinuities and reducing sensitivity to initialization.”

Self-Reinforced Deep Priors for Reparameterized Full Waveform Inversion

Published:Dec 9, 2025 06:30
1 min read
ArXiv

Analysis

This article likely presents a novel approach to full waveform inversion (FWI), a technique used in geophysics to reconstruct subsurface properties from seismic data. The use of "self-reinforced deep priors" suggests the authors are leveraging deep learning to improve the accuracy and efficiency of FWI. The term "reparameterized" indicates a focus on how the model parameters are represented, potentially to improve optimization. The source being ArXiv suggests this is a pre-print and the work is likely cutting-edge research.

Key Takeaways

    Reference

    “The article's core contribution likely lies in the specific architecture and training methodology used for the deep priors, and how they are integrated with the reparameterization strategy to improve FWI performance.”
