Laboratory-Scale Hydraulic Fracturing Data for Geothermal Simulation Benchmarking

Experimental results from hydraulic fracturing tests on 30 cm × 30 cm × 45 cm granite and marble samples under controlled boundary conditions. The dataset includes pressure-flow-rate responses, acoustic emission data from 32 seismic sensors, sample properties, and processing code. This collection was produced by RWTH Aachen University within the European Union's Horizon 2020 GEMex project.

Use Cases

• Benchmarking numerical simulation tools based on pressure versus flow-rate response data.
• Analyzing fracture propagation and mechanics using acoustic emission data from a dense sensor network.
• Verifying model assumptions and constitutive relationships for field-scale experiment design.
• Processing and interpreting seismic data with the included Python code.

Strengths

• Includes a complete collection of data from well-defined laboratory experiments on granite and marble samples.
• Contains acoustic emission data captured by a dense network of 32 seismic sensors.
• Provides mechanical and petrophysical properties of the tested rock samples.
• Comes with Python code for seismic data processing, facilitating reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
