Researchers have adapted a pre-trained vision foundation model (VFM), specifically DINOv3, for the task of characterizing natural and drilling-induced fractures in acoustic image logs. This adaptation proved more effective than training task-specific models from scratch, especially when limited annotated data was available. The adapted DINOv3 model demonstrated comparable accuracy to human interpretation and outperformed other models like U-Net, YOLOv8, and Swin Transformer in identifying fracture parameters, though its advantage diminished with smaller training datasets. The study also explored optimal decoder architectures and fine-tuning strategies, finding that a progressive upsampling decoder with full fine-tuning yielded the best results for DINOv3 configurations.
