On April 21, 2022, sewer camera surveys were conducted in boreholes TN and TL as part of Experiment 2 of the EGS Collab project. These surveys were performed during fluid injection into three zones in borehole TC to identify the depths of active fracture intersections. The goal was to place straddle packers precisely to capture the maximum amount of injected fluid and better characterize the created fracture system. The dataset includes video recordings from the downhole surveys along with a document that maps each injection zone and borehole survey to the corresponding video file. The document also provides key observational notes, corrected depth measurements based on tape references, injection flow rates, fracture response timings, and sensor calibration information. Depth readings from the video overlays are noted to be inaccurate, with more reliable measurements provided in the document.
