reservoir rock - Opis:
- The rock–brine–CO2 interaction significantly affects the mechanism and efficiency of the geological storage process. Therefore, learning and understanding the processes occurring in the pore space is extremely important to ensure the safe large-scale storage of this gas. A measurement procedure was developed to assess changes in petrophysical parameters under the influence of CO2. A specialized test stand was designed and built to simulate rock–brine–CO2 interaction under simulated reservoir conditions. The research was carried out on samples of carbonate rocks and Cambrian sandstones. In most cases, an improvement of filtration parameters in the 5–20% range was observed. In the case of samples in which the dominant mineral was calcite, the increase in filtration parameter values reached 200–400%. An increase in the diameter of the pore channels and a change in the surface roughness, as well as greater hydraulic connectivity of the pore space, will affect the capillary forces and the loss of continuity of the non-wetting fluid flow, limiting capillary trapping in the near-wellbore zone.
