Molecular Dynamics Investigation of Wettability Alteration of Quartz Surface under Thermal Recovery Processes [PDF]
Molecules, 2023 One of the primary methods for bitumen and heavy oil recovery is a steam-assisted gravity drainage (SAGD) process. However, the mechanisms related to wettability alteration under the SAGD process still need to be fully understood.

Green Lignosulphonate as co-surfactant for wettability alteration
Petroleum Research, 2020 Surfactant flooding is one of the common tertiary method to recover remaining oil in the reservoir, by reducing the interfacial tension (IFT) between two immiscible fluids nevertheless, current surfactant forms emulsion and difficult to achieve ultra-low

Wettability Alteration of Berea Sandstone for Gas Condensate Applications. [PDF]
ACS Omega, 2023 Gas condensate reservoirs can suffer significant decreases in production due to the buildup of liquid in the vicinity of the wellbore, which occurs when the bottom-hole flowing pressure drops below the dew point pressure. Consequently, the generated liquid hydrocarbons can hinder the movement of the produced gas by adhering to the surfaces, thereby ...

Digital rock workflow to calculate wettability distribution in a reservoir rock [PDF]
E3S Web of Conferences, 2023 Wettability has a strong influence on multi-phase flow behavior through reservoir rock. Reservoir rocks tend to have spatially varying wettability. Prior to contact with oil, rocks are almost always naturally water-wet. As oil invades the pore-space over

Evaluation of a New Agent for Wettability Alteration During Enhanced Oil Recovery [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2020 Wettability alteration is an important mechanism when applying surfactants during enhanced oil recovery (EOR). Moreover, in carbonate reservoirs, the rock has more tendencies to be oil-wet than those of sandstone reservoirs.
