Surfactants play a vital role in chemical enhanced oil recovery (cEOR). The amount of
surfactant loss caused by retention during flooding through reservoir rock is still a challenge …

Low salinity water injection (LSWI) is the process of injecting modified salinity brine with
controlled ionic composition to achieve increased oil recovery compared to conventional …

Wettability is one of the key controlling parameters for multiphase flow in porous media, and
paramount for various geoscience applications. While a general awareness of the …

The long-held industry view that the Low Salinity Effect (LSE) depends mainly on rock–fluid
interactions has led to failures and successes that can be explained by fluid–fluid …

The reservoir rock is made up of different minerals and its surface chemistry is influenced by
the reservoir environment. Well operations implemented during the life of a field induce …

Asphaltene adsorption on reservoir rock minerals causes wettability alteration and pore
plugging which subsequently reduces crude oil production. Also, it has a negative effect on …

Despite a large number of researches to understand the aggregation behavior and
adsorption mechanism of asphaltene, the effects of asphaltene molecular structure on the …

Many geological processes from oil recovery to underground CO2 storage are affected by
natural molecules adsorbed on rock surfaces. Yet, geochemical models tend to overlook …

The adsorption of asphaltene on the rock surface and the changes in its wettability are very
relevant issues in flow assurance and oil recovery studies, and for carbonate reservoirs, they …

Perhaps as much as 50% of the oil-in-place in carbonate formations around the world is
locked away in the easy to bypass microporosity. If some of this oil is unlocked by the …
