Particles mixed with highly viscous slickwater easily aggregate in the two-sided rough model and gradually form finger-like regions at the lower part of the inlet...

Also, the effects of natural fracture width and height, intersection angle with hydraulic fracture, and relative location with the inlet on proppant placement are investigated. The results identify that the natural...

During the subsequent period of liquid injection, liquid flows through the collapsed‐foam bank much more easily than further downstream. Beyond...

..., was used to determine spatially resolved T 2 spectra of the samples, and therefore the pseudo-pore-size distributions. The shift in the T 2 spectra of the core inlet and outlet showed opposite trends. The pore-size distribution of the inlet and outlet, inferred from T 2 distributions, were shifted...

... that no capillary condensation occurs along this secondary pore. In the beginning, the system is at equilibrium, and the pressures at two ends are the same and equal to p 1 . Because the pore is symmetric, the radii of the phase interface on both sides, near inlet and outlet, respectively, are the same...

...Usama Kadri Summary Very long slugs reaching several hundreds of pipe diameters may appear when transporting gas and liquid in horizontal pipes. Such slugs may cause serious operational and system failures. One could avoid the long slugs by pulsating the gas phase at the inlet at a specific range...

Diffusion, even though small in magnitude, is responsible for local mixing and making dispersion in porous media irreversible. Thus...

.... The GLCC is shown schematically in Fig. 1 . The gas and liquid mixture flows through an inclined inlet section, to enhance stratification, prior to reaching a tangential inlet slot. As a result, a swirl is formed causing the gas and liquid to separate due to the centrifugal force. The liquid moves toward...
