Experimental Brine-CO2 Flow-Through Data for Sleipner Reservoir Conditions

Experimental data from a 2016 laboratory test on a Utsira Sand core sample simulates CO2 geosequestration in shallow reservoirs. The dataset includes ultrasonic wave velocities, attenuation factors, axial and radial strains, and electrical resistivity measurements under Sleipner-like pressure conditions. It was collected at the National Oceanography Centre, Southampton, as part of the DiSECCS project funded by EPSRC and NERC.

Use Cases

• Calibrate seismic inversion models based on ultrasonic velocity and attenuation data.
• Validate electrical resistivity as a proxy for pore fluid distribution during CO2 injection.
• Model reservoir mechanical response using axial and radial strain measurements.
• Develop velocity-saturation relationships for field-scale seismic monitoring of CO2 plumes.

Strengths

• Data collected under controlled laboratory conditions simulating specific Sleipner reservoir pressures.
• Includes a derived velocity-saturation relationship extrapolated to field-scale seismic frequencies using a new rock physics theory.
• Linked to a peer-reviewed publication, providing context and validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single core sample experiment, limiting generalizability.
