Description
This dataset contains processed low-frequency Distributed Acoustic Sensing (LF-DAS) data collected between April 2 and April 12, 2024, during the Utah FORGE stimulation sequence involving wells 16A and 16B. The DAS measurements were acquired using a Silixa Carina interrogator unit on the FOGMORE distributed fiber optic sensing (DFOS) cable installed in well 16B. Installation details for the cable can be found at the report link below. Due to pre-existing damage to the cable, the signal-to-noise ratio is slightly lower than expected.
The data has been processed with a 0.5 Hz low-pass filter and a median filter in time, and values are expressed in units of nanostrain per second. All timestamps are in UTC. Data are provided in CSV format, with each file corresponding to a specific time segment. The repository also includes a channel map and a metadata catalog to support interpretation. Please see the included README for detailed dataset information. This dataset was produced under the FOGMORE R&D project (Fiber Optic MOnitoring for Reservoir Evolution), Utah FORGE R&D Project 3-2417, and was assembled by researchers from Rice University, Lawrence Berkeley National Laboratory, and partners, with documentation finalized in July 2025.
