“…There have been a significant number of experimental and simulation studies on the IFT data of CO 2 -water/brine systems at typical reservoir pressure and temperature conditions. In general, a fair agreement in the trends and values can be observed in the data reported by various research groups [15,20,28,29,72]. Figure 5 shows reproducibility of the effect of pressure on IFT data for CO 2 -water system at 298 K.…”

“…As shown in Figure 5, IFT sharply decreased with pressure when the CO 2 is gas and it becomes nearly constant when the CO 2 is liquid. It should be noted that Hebach et al, Bachu [15,20,28,29,72]. The lowest IFT reported by Chun et al [29] near the phase changing pressure was explained by Hebach et al [72] as a potential consequence of the placement of thermocouple away from the droplet.…”

“…Drop shape analysis techniques (e.g., ADSA and ADSA-NA) that are suitable for direct measurement of IFT at high pressure and temperature conditions were used for most of the reported CO 2 -water/brine IFT data [13,[15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In general, the drop shape analysis methods involve: (1) formation of aqueous phase droplet in continuous CO 2 phase as shown in (3) inputting the phase densities; and (4) obtaining IFT by matching the drop profile to the solutions of the Laplace equation [18,25].…”

“…About 5000 ppm NaCl brine and 50:50 mol% CO 2 -N 2 mixture were used as aqueous and gas phases, and the IFT measurements were conducted at 13 MPa and 333 K. It was found that 50 mol% N 2 has negligible effect on IFT (CO 2 -brine IFT of 38.7 ± 3.9 mN/m and 50:50 mol% CO 2 /N 2 mixture-brine IFT of 40.6 ± 3 mN/m) within experimental uncertainty. Kravanja et al [28] measured IFT between CO 2 stream containing Ar impurity and 23.26 g/L salinity brine and found that the presence of 5 and 10 vol.% Ar impurity in CO 2 stream has negligible effect on IFT within the temperature and pressure ranges of 40-90°C and 7.5-40 MPa.…”

Interfacial tension (IFT) between "native reservoir fluid" and "injected CO 2 " and the contact angle (CA) among the reservoir rock, native reservoir fluid, and injected CO 2 are major factors that dictate the relative permeability and capillary pressure characteristics which in turn control the fluid flow and distribution characteristics in the reservoir and cap rocks. This chapter is a comprehensive review on the state-of-the-art of the experimentally measured and theoretically predicted IFT and CA data of water/brine-CO 2-quartz/calcite/mica systems that are relevant to CO 2 sequestration. Experimental techniques used to generate the IFT and CA data and details of molecular simulations used to predict the data are discussed. Respective comparisons of the IFT and CA data reported by various research groups are also made. Possible reasons for disagreements in the published literature are discussed, and suggestions are made for future research in this area to address the potential technical issues in order to obtain reproducible data.

Free water storage capacity, an important characteristic of land surface related to runoff process, has a significant influence on runoff generation and separation. It is thus necessary to derive reasonable spatial distribution of free water storage capacity for rainfall-runoff simulation, especially in distributed modeling. In this paper, a topographic index based approach is proposed for the derivation of free water storage capacity spatial distribution. The topographic index, which can be obtained from digital elevation model (DEM), are used to establish a functional relationship with free water storage capacity in the proposed approach. In this case, the spatial variability of free water storage capacity can be directly estimated from the characteristics of watershed topography. This approach was tested at two medium sized watersheds, including Changhua and Chenhe, with the drainage areas of 905 km2 and 1395 km2, respectively. The results show that locations with larger values of free water storage capacity generally correspond to locations with higher topographic index values, such as riparian region. The estimated spatial distribution of free water storage capacity is also used in a distributed, grid-based Xinanjiang model to simulate 10 flood events for Chenhe Watershed and 17 flood events for Changhua Watershed. Our analysis indicates that the proposed approach based on topographic index can produce reasonable spatial variability of free water storage capacity and is more suitable for flood simulation.
