Mathematical Model of One-dimensional Miscible Fluid Injection in Fractured Porous Media

Miscible porous media displacements driven by non-vertical injection wells

High-resolution simulations are employed to identify and analyse the mechanisms dominating miscible porous media displacements generated by inclined injection wells. Compared to vertical injection wells, significant differences are observed that strongly influence breakthrough times and recovery rates. Constant density and viscosity displacements, for which the velocity field is potential in na...

Instability Analysis of Miscible Displacements in Homogeneous Porous Media

Experimental Investigation on Asphaltene Deposition in Porous Media During Miscible Gas Injection

In this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. The two different rock materials, limestone and sandstone, are used as a representative of porous media. Dynamic flow experiments indicate that the increase of natural gas injection inc...

Fluid flows through fractured porous media along Beavers-Joseph interfaces

We study a fluid flow traversing a porous medium and obeying the Darcy’s law in the case when this medium is fractured in blocks by an ε-periodic (ε > 0) distribution of fissures filled with a Stokes fluid. These two flows are coupled by a Beavers-Joseph type interface condition. The existence and uniqueness of this flow in our ε-periodic structure are proved. As the small period of the distrib...

Validity of the one-dimensional limp model for porous media

A straightforward criterion to determine the limp model validity for porous materials is addressed here. The limp model is an "equivalent fluid" model which gives a better description of the porous behavior than the well known "rigid frame" model. It is derived from the poroelastic Biot model assuming that the frame has no bulk stiffness. A criterion is proposed to identify the porous materials...
