We investigate the physics, chemistry, and techno-economics of CO2 storage underground

Our research includes exploring fundamental pore scale fluid dynamics, developing digital rocks analysis techniques, increasing the accuracy of field scale reservoir simulation, and evaluating the feasibility of scaling up CO2 storage to climate relevant scales.

    Successful industrial scale carbon dioxide injection into deep saline aquifers will be dependent on the ability to model the flow of the fluid and to quantify the impact of various trapping mechanisms. The effectiveness of the models is in turn dependent on high quality laboratory measurements ofbasic multiphase flow properties such as relative permeability and residual trapping at reservoir conditions. At the same time there exists general uncertainty around the few existing published data on these properties for CO2-brine systems. In this study we present results from a newly constructed reservoir condition coreflooding and imaging laboratory designed to measure multiphase flow properties, capillary pressure, relative permeability and residual trapping at a range of reservoir conditions. The proper approach to measuring relative permeability for CO2-brine system is proposed and demonstrated. The changes in residual trapping correlated to pressure, temperature, brine salinity, interfacial tension, and contact angle are also reported. We also show with a combination of simulations of corefloods and experiments performed at various conditions that high precision results can be obtained for this system when the appropriate conditions are used.

    Injection of CO<inf>2</inf> into the subsurface is of interest for CO <inf>2</inf> storage and enhanced oil recovery (EOR). There are, however, major unresolved questions around the multiphase flow physics and reactive processes that will take place after CO<inf>2</inf> is injected, particularly in carbonate rock reservoirs. For example, the wetting properties of CO<inf>2</inf>-brine- rock systems will impact the efficiency of EOR operations and CO<inf>2</inf> storage but reported contact angles range widely from strongly water-wet to intermediate wet. Similar uncertainties exist for properties including the relative permeability and the impact of chemical reaction on flow. In this presentation we present initial results from laboratory studies investigating the physics of multiphase flow and reactive transport for CO<inf>2</inf>-brine systems. We use traditional and novel core flooding techniques and x-ray imaging to resolve uncertainties around the CO<inf>2</inf>-brine contact angle, relative permeability, residual trapping, and feedbacks between chemical reaction and flow in carbonate rocks.
