Influence of Rock Wettability on Reservoir-Scale CO2 Geo-Sequestration
MetadataShow full item record
The focus of this research is to investigate the influence of rock wettability on CO2 movement through porous media. By performing different multiphase flow reservoir simulations on a hectometre scale, this research investigates the effects of wettability, wettability spatial distribution, and factors affecting wettability on the efficiency of CO2 trapping mechanisms. The results of this research show that reservoir wettability significantly influences CO2 storage efficiency and that water-wet reservoirs are preferable CO2 sinks.

Effect of wettability heterogeneity and reservoir temperature on CO2 storage efficiency in deep saline aquifersAl-Khdheeawi, E.; Vialle, Stephanie; Barifcani, Ahmed; Sarmadivaleh, Mohammad; Iglauer, Stefan (2018)Reservoir heterogeneity at various length scales is a well-established fact. This includes reservoir wettability - a key factor influencing CO 2 geo-storage efficiency and containment security - which changes with depth, ...
Al-Khdheeawi, Emad A.; Vialle, Stephanie; Barifcani, Ahmed; Sarmadivaleh, Mohammad; Iglauer, Stefan (2017)Reservoir wettability – the tendency of a rock surface to be in contact with one fluid more than other fluids – can vary substantially from strongly water-wet to strongly CO2-wet. However, the influence of such differences ...
Sari, Ahmad; Xie, Sam; Chen, Yongqiang; Saeedi, Ali; Pooryousefy, Ehsan (2017)Wettability alteration appears to be the main mechanism of low salinity water flooding in carbonate reservoirs. However, what factor(s) controls the wettability alteration is not clearly defined. We hypothesized that zeta ...
