Rock Anisotropy Hydraulic Fracture Experiments with Acoustic and Pressure Data

Experimental data from École Polytechnique Fédérale de Lausanne supports the manuscript 'Rock anisotropy promotes hydraulic fracture containment at depth'. The dataset includes raw and processed measurements from four experiments (K1, T2, M3, M4), containing active acoustic monitoring data, fluid injection pressure readings, and confining stress data. Processed results include synchronized pressure data and detailed acoustic emission event catalogs.

Use Cases

• Modeling hydraulic fracture propagation based on synchronized pressure and acoustic emission data.
• Analyzing the influence of anisotropic rock properties on fracture containment using confining stress measurements.
• Developing acoustic emission-based monitoring techniques for fracture experiments using the provided waveform and event data.

Strengths

• Data is organized into five distinct folders for four separate experiments, providing a structured experimental context.
• Includes both raw data (e.g., .bin waveform files, .csv pump readings) and processed results (e.g., AE event catalogs, synchronized pressure data).
• Data collection involved multiple instrument types, including an active acoustic monitoring system, syringe pumps, and pressure transducers.

Limitations

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