Abstract
We present a fully compositional, three-dimensional (3D) numerical modeling of an on-shore deep saline formation for system analysis of CO2 storage. We use data from a reservoir in Malmö, Sweden and analyze the reservoir’s response to the injection of 60,000 t of CO2 over a period of two years under realistic reservoir conditions. This helps to explore possible environmental impacts of a future CO2 sequestration test project for the study area. We focus mainly on fluid and mass transports. The results show that the pore overpressure does not exceed a level considered critical for the creation of hydraulic fractures. Our study also indicates how the amount and extent of salt precipitation near the injection well may be altered by variations in relative permeability and capillary pressure. We show that the temperature and strata inclination’s effects are marginal. Further, results indicate a great potential for reactions between CO2, water, and rock. In summary, this numerical simulation addresses both transport and precipitation of salt dissolved in the fluid. Therefore, it provides both a better understanding of the fate of the CO2 plume in a reservoir in time and guidance for practical decisions.
