Analysis of fluid flow in naturally fractured reservoirs (NFRs), as a highly heterogeneous and
complex system, requires a detailed study of the fracture-matrix interactions. The main …

Imbibition is very common, occurring in life, material, chemistry, and energy. It plays an
important role in enhanced oil recovery (EOR). The development of many reservoirs is …

Spontaneous imbibition has been proved to be a promising enhanced oil recovery method
for tight reservoirs, but the mechanisms of spontaneous imbibition oil recovery (SIOR) are …

The imbibition of water with surfactants, including spontaneous imbibition and forced
imbibition, is of great significance for enhanced oil recovery (EOR) in tight sandstone …

Based on field conducts, it is found that a lower flowback rate results in a higher oil recovery
in a tight sandstone reservoir. Spontaneous imbibition, as a main mechanism of oil …

Lower-phase microemulsions with core-shell structure were prepared by microemulsion
dilution method. The high temperature resistant systems were screened and the …

Microfluidics is a promising approach for investigating processes at the pore scale of rocks,
such as oil recovery, due to their similar size range. Unlike conventional core flooding and …

Under certain boundary conditions during spontaneous brine imbibition into oil-saturated
porous rocks, it is possible for co-and counter-current flow to occur simultaneously. These …

Counter-current imbibition occurs when brine spontaneously displaces oil from a water-wet
porous rock. In experiments that attempt to simulate the production of oil from fractured …

Solutions are investigated for 1D linear counter-current spontaneous imbibition (COUSI). It is
shown theoretically that all COUSI scaled solutions depend only on a normalized coefficient …
