Storage in subsurface geologic formations, principally saline aquifers, is currently under development as a major approach to counter anthropogenic CO 2 emissions. To ensure the stability and long-term viability of geologic carbon storage, injected CO 2 must be kept in place by an overlying cap rock of very low permeability. Capillary forces in the cap rock act to prevent upward migration and escape of the stored supercritical fluid, with interfacial tension (IFT) between the aqueous brine phase and the CO 2 phase being the primary control. However, published experimental CO 2 -water IFT data vary widely, mainly because of inadequate experimental protocols or inappropriate use of bulk-fluid properties in computing IFT from experimental observations. Only two published data sets were found to meet all criteria of merit for an accurate measurement of IFT over the entire range of pressure (5-45 MPa) and temperature (298-383 K) pertinent to geologic carbon storage. In such circumstances, molecular simulations can enhance the utility of limited data when used to validate assumptions made in their interpretation, resolve discrepancies among data, and fill gaps where data are lacking. Simulations may also be used to provide insight into the relationship between IFT and fundamental properties, such as the strength of the CO 2 -H 2 O interaction. Through molecular dynamics simulations, we compared the quality of three CO 2 models and two H 2 O models (SPC/E and TIP4P2005) in predicting IFT under the pressure and temperature conditions relevant to geologic CO 2 sequestration. Interfacial tension at fixed temperature simulated via molecular dynamics decreased strongly with increasing pressure below the critical CO 2 pressure of 7 MPa, then leveled off, in agreement with experiment, whereas increasing temperature from 300 to 383 K at fixed pressure had little effect on IFT, which is also

“…In order to measure the interfacial properties of the mixtures as those considered in this work, by far the most common technique is the use of pendant drop tensiometry [9,10,11,12,13,14,15,16,17,18,19,20,21]. On the other hand, theoretical descriptions of these mixtures have been made by employing Density Functional Theory (DFT) [13,14,22], Density Gradient Theory (DGT) or Square Gradient Theory (SGT) [23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38].…”

An analysis of the above mentioned references reveals that there are key points that must be taken into account: First, an unequivocal full description of interfacial properties requires -at least-two independent approaches, as some previous works have demonstrated (see for instance and references therein).…”

Experimental data for the interfacial tension of pure water and brine against CO 2 at reservoir conditions have been reported by several authors (Chalbaud et al 2007, Chalbaud et al 2010, Chalbaud et al 2009, Chalbaud et al 2006, Chiquet et al 2009, Chun and Wilkinson 1995, Georgiadis et al 2010, Hebach et al 2002, Kvamme et al 2007, Nielsen et al 2012, Shariat et al 2011, Shariat et al 2012, Sutjiadi-Sia et al 2008, Yan et al 2001.

“…Therefore, reports which do not indicate the position of the thermocouple and/or do not report the temperature near the CO 2 -water interface should be excluded from a data set when used for comparison. To help validating our IFT data, we made a comparison of our measurements with the published results of , Chun and Wilkinson (1995), and Kvamme et al (2007). In Figure 3, the pressure dependency of the measured CO 2 -distilled water IFT is depicted.…”

SUMMARYCarbon capture and storage (CCS) has the potential for reducing CO2 emissions to the atmosphere. This option includes storage strategies such as CO2 injection into deep saline aquifers, depleted oil and gas reservoirs, and unmineable coal seams. This process is largely controlled by the interactions between CO2, the reservoir fluid and reservoir rock. In particular, the wettability of the rock matrix has a strong effect on the distribution of the injected CO2 into geological formations.In this study, the wetting behavior of Bentheimer sandstone slabs and CO2 and/or flue gas is investigated by means of contact-angle measurements. In addition, the interfacial tension between CO2 and/or flue gas and connate water was determined. The experiments were conducted in a pendant-drop cell, adapted to allow captive-bubble contact-angle measurements and performed at a constant temperature of 318 K and pressures varying between 0.2 and 15 MPa, typical in-situ conditions.The experimental contact angle measurements show that the Bentheimer sandstone/water system is (and remains) water-wet even at high pressures with CO2 and/or flue gas injection. The determined data of the contact angle of the water-sandstone system demonstrate a strong dependence on the bubble size and surface roughness with CO2 and flue gas injection.
