Cape EGS: Frisco Pad Flow Test Microseismic DAS Data

Awaiting release License 

This dataset contains microseismic data acquired during the Frisco pad flow test project led by Fervo Energy, conducted between August and September 2025 near the Utah FORGE geothermal site. The data were recorded using a Distributed Acoustic Sensing (DAS) fiber installed in well 16B, with additional geophone channels included in the dataset. Measurements were collected using a Silixa iDAS system and stored in HDF5 (H5) format. Within each file, the first six traces correspond to geophone channels and the remaining traces correspond to DAS measurements along the fiber in well 16B.

The dataset consists of sequential time-based HDF5 files, each representing a different segment continuous acquisition. File names correspond to the acquisition start time in UTC. Each file contains strain-rate measurements recorded at a 1000 Hz output data rate with a gauge length of 10 m and a spatial sampling interval of approximately 2.04 m along the fiber. The primary data are stored as 16-bit integer strain-rate values in a two-dimensional array organized by time and spatial channel, accompanied by a corresponding microsecond-resolution time vector.

Metadata describing more acquisition parameters, instrument configuration, and system settings are embedded within the HDF5 files. These metadata include details such as pulse rate, spatial configuration of the fiber, instrument information, and timing references. The recorded measurements represent strain-rate data with units of (nm/m)/s * Hz/m, and users should consult the embedded acquisition metadata for additional parameters required to interpret the measurements.
