Distributed Acoustic Sensing (DAS) and hydrophone data provide geophysical baseline measurements for the UKGEOS geothermal research site in Glasgow. The dataset includes both active source and passive seismic measurements collected from fiber-optic cables and a co-located hydrophone array prior to heat pump installation. It was funded by the UK Unconventional Hydrocarbons grant and acquired by the British Geological Survey.
Use Cases
- Compare seismic signal fidelity between the novel DAS fiber-optic measurements and the co-located hydrophone array data.
- Analyze passive DAS measurements to characterize baseline subsurface vibrations at the repurposed coal mine site.
- Process active source DAS survey data to establish baseline velocity models for the geothermal facility.
- Investigate the potential of DAS for monitoring geothermal production activities using the pre-installed fiber-optic borehole infrastructure.
Strengths
- Provides a direct comparison dataset between novel DAS technology and traditional hydrophone seismic monitoring.
- Captures baseline conditions at a dedicated geothermal research observatory prior to operational disturbance.
- Data was collected using pre-installed fiber-optic cable infrastructure within the borehole, enabling dense spatial sampling.
Limitations
- The dataset's specific temporal coverage, spatial extent, and data volume (e.g., recording duration, channel count) are not detailed.
- As baseline data collected before heat pump installation, it does not contain signals from active geothermal operations.
- Specialized knowledge in seismic processing and DAS technology is required for effective analysis.
