Quantification of non-linear multiphase flow in porous media [PDF]
Geophysical Research Letters, 2020 AbstractWe measure the pressure difference during two‐phase flow across a sandstone sample for a range of injection rates and fractional flows of water, the wetting phase, during an imbibition experiment. We quantify the onset of a transition from a linear relationship between flow rate and pressure gradient to a nonlinear power‐law dependence. We show

Multiphase Flow in Porous Media [PDF]
, 2014 In the hydrocarbon reservoirs that are normally saturated with two or more fluids, in order for better description of the flowing fluids behaviors and rock fluid interaction, the concept of relative permeability and capillary pressure should be exploited.

A MgNO Method for Multiphase Flow in Porous Media [PDF]
This research investigates the application of Multigrid Neural Operator (MgNO), a neural operator architecture inspired by multigrid methods, in the simulation for multiphase flow within porous media. The architecture is adjusted to manage a variety of crucial factors, such as permeability and porosity heterogeneity.

Stochastic Flowpath Analysis of Multiphase Flow in Random Porous Media [PDF]
SIAM Journal on Applied Mathematics, 2000 Multiphase flow in random porous media is studied by means of a stochastic flowpath approach, which is built upon concepts of differential geometry. This approach replaces the partial differential equations of flow by a set of ordinary differential equations along the flowpaths.

Multiphase Flow in Mixed-wet Porous Media [PDF]
, 2023 Multiphase flow in porous media is important in a wide range of industrial and environmental processes. It is well-known that the fluids’ relative affinity to the porous media (i.e., wettability) is a crucial factor controlling multiphase flow in porous ...

Optimization of Non-Uniform Perforation Parameters for Multi-Cluster Fracturing
Energies, 2022 Stress shadowing affects the simultaneous propagation of fractures from multiple perforation clusters. Employing uniform perforation parameters for all clusters cause the unbalanced growth of fractures, which arouses the demand of optimizing non-uniform ...

Upscaling multi-component two-phase flow in porous media with partitioning coefficient [PDF]
, 2011 This paper deals with the upscaling of multicomponents two-phase flow in porous media. In this paper, chemical potential equilibrium at the interface between both phases is assumed to be described by a linear partitioning relationship such as Raoult or ...
