Capillary number, understood as the ratio of viscous force to capillary force, is one of the
most important parameters in enhanced oil recovery (EOR). It continues to attract the interest …

Polymer flooding is drawing lots of attention because of the technical maturity in some
reservoirs. The first commercial polymer flooding in China was performed in the Daqing …

Characterizing the trapped phase in porous media is essential for many engineering
applications, such as enhanced oil recovery, nuclear storage, and geological sequestration …

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 …

Models that describe two-fluid flow in porous media suffer from a widely recognized problem
that the constitutive relationships used to predict capillary pressure as a function of the fluid …

Synchrotron x-ray microtomography combined with sensitive pressure differential
measurements were used to study flow during steady-state injection of equal volume …

High‐resolution X‐ray microcomputed tomography (micro‐CT) data are used for the
accurate determination of rock petrophysical properties. High‐resolution data, however …

Dynamics of flowing air in partially water‐saturated, porous geological formations are
governed by a wide range of forces and parameters. These dynamics are reviewed in the …

Capillary number theory is very important for chemical flooding enhanced oil recovery. The
difference between microscopic capillary number and the microscopic one is easy to …

We present a pore-network model study of capillary trapping in water-wet porous media. The
amount and distribution of trapped non-wetting phase is determined by the competition …
