... Abstract The role of wettability is crucial in the extraction of hydrocarbons as it determines how well the oil adheres to the rock surface, directly impacting the efficiency of the extraction process. Numerous studies have been conducted to modify the wettability of rocks to a favorable state...

... opposite statistical significances. However, their synergy was evident in the high positive significance of their association, due to the association of monovalent and bivalent cations. In addition, molecular dynamics calculation revealed that monovalent ions improve the wettability of water...

... Abstract The injection of low-salinity water in oil reservoirs to improve the recovery of oil is effective in sandstones but its application in carbonates is still a matter of debate. To address the wettability of rock-brine-oil systems and the recovery of oil in a porous medium, a new...

... Abstract Wettability is an important property in reservoir characterization. For the heterogeneous carbonate reservoirs in the Brazilian Pre-Salt, parameters that represent wettability are needed to obtain improved reservoir models. In this work, we applied contact angle measurements to analyze...

... and dead oil of the same field as the core. The sample was aged for 34 days to simulate the wettability reservoir conditions. During the test, the syntethic seawater (SW) injection was started, and, after eight days, it was switched to ten times diluted seawater (SW10x) for 22 days. Oil production...

... Abstract Experimental data confirm that the EOR-effects observed during Smart Water flooding can be explained by wettability alteration toward more water-wet conditions. Detailed knowledge about the important crude oil – brine – rock parameters affecting reservoir wetting, fluid flow...

... for enhanced oil recovery. Some of these involved wettability measurements, such as the Amott test, but these are typically time consuming. This communication reports on the use of low-field nuclear magnetic resonance (NMR) to probe rock wettability in the presence of different formulations. Based...

... In oil reservoirs, a significant amount of oil resides in small pores where nanoscale phenomena dominate wettability and drive the mobility of oil. Nanoscale phenomena hence control the quantity of oil to be recovered on the reservoir scale. However, there are significant scientific challenges...

... processes, such as ion exchange, wettability alteration, and mobility control. This process has matured over the years, but the alteration of the salinity of injected brine during WAG has not been experimented extensively. This paper investigates the effect of injected brine salinity during water...

... offshore Brazil, especially in carbonates with oil or mixed wettability. Selection of the best production strategy for this reservoir was determined through a full-field simulation using a commercial simulator with double porosity model. The main application of this work is the possible implementation...
