Spontaneous imbibition is of particular importance to oil recovery from fractured reservoirs.
There has been a surge in the growth of technical literature over the past 5 years. This …

Brine-dependent recovery, which involves injected water ionic composition and strength,
has seen much global research efforts in the past two decades because of its benefits over …

The composition of the injecting brine has a profound effect on the efficiency of water-based
enhanced oil recovery (EOR) methods. Recently, we observed that not only is the …

Previous studies of crude oil/brine/rock (COBR) and related systems showed that wettability
and its effect on oil recovery depend on numerous complex interactions. In the present work …

A reproducible method has been developed to create homogeneous oil-wet chalk material
wettability with and without initial water saturation. This was accomplished by aging crude oil …

Imbibition in water-wet matrix blocks of fractured porous media is commonly considered to
be countercurrent. The modeling studies of this paper indicate that when a matrix block is …

Advanced waterflooding is a process in which the ionic strength as well as the ionic
composition of the injected water is tuned to improve the oil recovery. It has been observed …

Injection of brine with lower salinity than the connate brine has proven to give a moderate
increase in oil recovery in sandstones. Recent research has shown that this process will …

Water chemistry has a profound effect on the stability of the water film and desorption of
organic oil components from the mineral surfaces in a water—based enhanced oil recovery …

Spontaneous imbibition is of special importance to oil recovery from fractured reservoirs.
Laboratory measurements of volume of liquid imbibed versus time are often used in the …
