The wettability of carbonate rocks is often oil-wet or mixed wet. A large fraction of oil is still
remained in carbonate reservoirs, it is therefore of particular significance to implement …

A significant fraction of the conventional oil reserves globally is in carbonate formations
which contain a substantial amount of residual oil. Since primary and secondary recovery …

Changing oil-wet surfaces toward higher water wettability is of key importance in subsurface
engineering applications. This includes petroleum recovery from fractured limestone …

Nearly half of the world's oil reserves are found in carbonate reservoirs, which have
heterogeneous formation characteristics and are naturally fractured. Because of the …

With the ever increasing demand for energy to meet the needs of growth in population and
improvement in the living standards in particular in developing countries, the abundant …

Enhanced oil recovery (EOR) techniques are receiving substantial attention worldwide due
to the major decline in the available oil resources. However, lots of challenges and …

The most common fallacy in the quest for the optimum stimulation treatment in shale plays
across the country is to treat them all just like the Barnett Shale. There is no doubt that the …

Changing the wetting state of materials is a growing field of research in many areas of
engineering and science. In the oil industry, the term wettability alteration usually refers to …

Wettability alteration is an important method to increase oil recovery from oil-wet carbonate
reservoirs. Chemical agents like surfactants are known as wettability modifiers in carbonate …

More than half of the global oil reserves are in carbonate reservoirs. Carbonate rocks,
however, in most cases tend to be mixed-wet or oil-wet. Wettability alteration of carbonate …
