Brine-CO2 Flow-Through Test Data for Shallow Storage Reservoir Simulation

Experimental data from a brine-CO2 flow-through test conducted on a 45% porosity synthetic sandstone core at the National Oceanography Centre, Southampton, during 2015-2016. The data were collected to assess geophysical monitoring and deformation under simulated shallow North Sea Sleipner-like CO2 storage conditions. The work was part of the DiSECCS project funded by the UK's EPSRC and NERC.

Use Cases

• Modeling relative permeability of CO2 and brine based on fractional flow rates mentioned in the description
• Correlating geophysical signatures with hydrodynamic behavior using ultrasonic P- and S-wave velocity and attenuation data
• Analyzing rock deformation under cyclic pressure scenarios based on axial, radial, and volumetric strain measurements
• Investigating electrical resistivity changes in porous media during multi-phase fluid flow

Strengths

• Data collected under simulated realistic shallow CO2 geosequestration conditions similar to North Sea Sleipner reservoirs
• Includes multiple concurrent measurements: ultrasonic wave velocities, attenuation, strains, resistivity, and relative permeability
• Experiment was part of a funded research project (DiSECCS, EPSRC grant EP/K035878/1)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect experimental bias inherent to a single synthetic sandstone sample and lab setup
