.... Based on these results, a new technical approach to enhancing fluid flow in reservoirs was formulated, and a full-scale field experiment in Alberta was initiated in December 1998. The field trial successfully showed that periodic application of large amplitude excitation to a porous medium experiencing...

... rectangular cavities filled with a porous medium. The smaller cavity is located at the top of the larger one. The larger cavity is filled initially with glycerin while the smaller one contains fresh water. At the initial time, the fresh water is injected with either constant flow rate (numerical) or constant...

... through a porous medium have the most impact on the shape of the relative permeability curves. Because relative permeability is a strong function of saturation, an accurate measurement of saturation levels in various types of two-phase flow experiments is required. Weighing and volumetric methods...

... was carried out to achieve a better mechanistic understanding of emulsion flow and its mathematical representation. In the first phase of this research, the physical mechanisms were observed during stable emulsion flow in a porous medium. Particularly, emulsion rheology and droplet capture for the system...

... analyzed using a porous medium approach and an equivalent homogeneous single phase method. The pressure gradients predicted by the latter are consistent with the measured pressure gradients in all the experiments. Contrary to the well-known Romm's relative permeability versus saturation relationship...

... Abstract The fluid flows in porous medium is described by the diffusion type of partial differential equation. In deriving the flow equation for the constant compressibility fluids, an important assumption is made regarding the magnitude of the pressure gradient: it is assumed...

... Abstract The flow of a single compressible fluid phase through a deformable heterogeneous porous medium is considered. It is shown that for the particular medium being considered the equations which describe fluid motion depend on the structure of the heterogeneous medium. In the limiting case...

... medium. 5–7 This answer is incomplete, however, because the presence of a porous medium is not a prerequisite for the appearance of viscous fingers. Indeed, pioneering studies of viscous fingering 8–9 did not even use a porous medium. These studies used a seemingly simple system called a Hele-Shaw cell...

... flow through porous media, relatively few efforts have been made towards the mathematical simulation of emulsion rheology and propagation in a porous medium. Only a few researchers have attempted to simulate emulsion flow through porous media, and most of them have considered the case for which...

... Abstract This paper presets a new mathematical formulation chat provides a realistic and appropriate representation of foam behaviour in a porous medium. Foams are gaining increasing importance in the petroleum industry in a number of roles, notably as mobility control and/or blocking agents...

MRF's were measured are 200 ºC and 6.0 MPa in 30 cm long and 5.7 cm diameter cores composed of unconsolidated sand. Tests were conducted at three...

... arrangement wasdeveloped. The porous medium was enclosed in a high temperature resistant epoxyresin in such a manner that the Flow through the core was linear. Rheologicalcharacterization of the polymer solutions and their flow through the porousmedia were carried out in a completely metal-free system...
