Description

The experimental dataset used in the publication "CO2 Mobility Reduction using Foam Stabilized by CO2- and Water-Soluble Surfactants . Steady-state foam experiments co-injected gaseous CO2 and aqueous surfactant solution at varying gas flow velocities and gas fractions using six commercially available surfactants. One anionic surfactant, which is considered a benchmark foam stabilizer because it has been extensively studied, and five partially CO2 soluble non-ionic surfactants were investigated. The repository contains 8 separate files, one file for each of the six foam experiments performed using different surfactants, one for the water-CO2 relative permeability experiments, and one file which contains compiled data. The seven files containing experimental (foam and relative permeability) data have a similar structure. They contain two worksheets, one for the gamma annotation saturation measurements (gasm) and calculations, and one for the data logged continuously with time during the duration of the experiments (data). The time logged datasheet includes injection rates (qwater and qco2), core temperatures (tcore), temperature in the lab (troom), pressures (pin, pout, psleeve, pbackp.), mass of produced fluids (balance and prod mass), production rate (qdSSW), average saturation from produced mass(avrqddSSW), measured differential pressure (dp1, line and dp2, line), additionally corrected differential pressure and moving mean. Key core and thermophysical parameters of the experiments can be found in the top part of the files. The second datasheet contains gamma annotation saturation measurements and calculations obtained at each injection rate when steady state conditions were obtained. Reference scans are included.
