PoroTomo Distributed Acoustic Sensing Data from Brady Hot Springs

Distributed Acoustic Sensing data from the PoroTomo Natural Laboratory includes raw SEG-Y and HDF5 files from horizontal and vertical fiber optic deployments. Data collection occurred in March 2016, with files organized into 30-second and daily intervals. The dataset is hosted by the Department of Energy on AWS via the Open Energy Data Initiative.

Use Cases

• Analyze SEG-Y and HDF5 files for seismic signal patterns during the March 2016 recording period.
• Process raw DAS data from the horizontal zigzag trenched fiber to study near-surface wave propagation.
• Use the vertical DASV data from the 363-meter well to model subsurface poroelastic properties.
• Apply metadata on recording gaps to filter and quality-check the time-series data streams.

Strengths

• Data collection spans a defined 18-day period in March 2016 for horizontal DAS and 12 days for vertical DAS.
• Includes raw data files in two standard geophysical formats, SEG-Y and HDF5.
• Provided with tutorial Jupyter Notebooks for working with the AWS-hosted data.

Limitations

• Dataset size and row counts are unspecified, making it difficult to assess computational requirements.
• As raw field data, it likely requires significant geophysical expertise and preprocessing for analysis.
