EGS Collab Experiment 2: Core Photographs and Descriptions

Published by Lawrence Berkeley National Laboratory | Department of Energy | Catalog Last Checked: March 23, 2026 at 09:41 PM | Dataset Last Updated: February 28, 2024 at 06:56 PM
This submission contains photographs of rock core collected from EGS Collab Experiment 2 (and 3) boreholes. Cores were generally photographed in about 1-foot sections using Nikon D3300 DSLR cameras from two angles about 90 degrees apart, wet and dry. Core photos are provided here in .zip files for each well, organized in subfolders by depth interval. Panoramic photographs of the rock cores as well as description and anomaly logs are also available here.
