Latent Diffusion Modeling of Two- and Three-dimensional Fracture Networks with Sparse Observation Conditioning
Jiawei Shen, Hongkyu Yoon, Jonghyun Lee
Characterizing subsurface fracture networks is challenging because geometry and connectivity are sparsely observed and uncertain away from measurements. We develop a latent diffusi…

Subsurface Characterization using Ensemble-based Approaches with Deep Generative Models
Jichao Bao, Hongkyu Yoon, Jonghyun Lee
Estimating spatially distributed properties such as hydraulic conductivity (K) from available sparse measurements is a great challenge in subsurface characterization. However, the…
