Brine-CO2 flow-through test in synthetic sandstone with oblique fractures
NERC grant NE/R013535/1. Here we present the dataset collected during a brine-CO2 flow-through test using a synthetic sandstone with oblique fractures, performed under realistic reservoir conditions stress. We monitored geophysical, mechanical and transport properties, for drainage and imbibition conditions, representative of the injection and post-injection stages of the CO2 storage process. We collected ultrasonic P- and S-wave velocities and their respective attenuation factors, axial and radial strains, electrical resistivity, pore pressure, temperature and brine and CO2 partial flows (from which relative permeability was later calculated).

The synthetic sandstone was manufactured in the Rock Physics laboratory at the NOC, using the experimental procedure described in https://doi.org/10.1111/1365-2478.12699, but including aluminium disks to create the fractures ( https://doi.org/10.1016/j.petrol.2019.106551). Then, the sample is originally saturated in seawater-like synthetic brine and pressurized at 40 MPa of (hydrostatic) confining stress and 10 MPa of pore pressure. Thereafter, brine and CO2 were injected at increasing partial flow rates of CO2 with respect to brine (20% stepwise), till 100% of CO2 flow-through. After the maximum CO2 saturation was reached, the sample was flushed-back with the original brine to simulate natural aquifer recharge after ceasing CO2 injection activities. During the test, ultrasonic and resistivity data were collected every one pore volume time, while strains and permeability in continuous.
