“…(Yeung and Mitchell, 1993) Because nanoporous soils can act as semi-permeable membranes, they are capable of inducing coupled transport (Yeung and Mitchell, 1993). The characterization of coupled flows through semi-permeable membranes requires non-equilibrium (irreversible) thermodynamics formalism with the following assumptions (Baranowski, 1991, Yeung and Mitchell, 1993, and Malusis et al, 2012 i. Local equilibrium…”

The average pore size in unconventional, tight-oil reservoirs is estimated to be less than 100 nm. At this pore size, Darcy flow is no longer the dominating flow mechanism and a combination of diffusive flows determines the flow characteristics. Concentration driven selfdiffusion has been well known and included in the flow and transport models in porous media.However, when the sizes of the pores and pore-throats decrease down to the size of the hydrocarbon molecules, the porous medium acts like a semi-permeable membrane, and the size of the pore openings dictates the direction of transport between adjacent pores. Accordingly, characterization of flow and transport in tight unconventional plays requires understanding of their membrane properties.This Master of Science thesis first highlights the membrane properties of nanoporous, unconventional reservoirs and then discusses how filtration effects can be incorporated into the models of transport in nanoporous media within the coupled flux concept. The effect of filtration on fluid composition and its impact on black-oil fluid properties like bubble point pressure is also demonstrated.

“…The application of LNET to membrane systems has been studied previously [26][27][28][29], however the focus has been primarily on transport phenomena with the membrane treated as a single discontinuity separating two regions. In contrast, this paper is concerned with the membrane itself, and the deformations which occur during the process of growth due to accretion.…”

We investigate the stability of growing vesicles using the formalism of nonequilibrium thermodynamics. The vesicles are growing due to the accretion of lipids to the bilayer which forms the vesicle membrane. The thermodynamic description is based on the hydrodynamics of a water/lipid mixture together with a model of the vesicle as a discontinuous system in the sense of linear nonequilibrium thermodynamics. This formulation allows the forces and fluxes relevant to the dynamic stability of the vesicle to be identified. The method is used to analyze the stability of a spherical vesicle against arbitrary axisymmetric perturbations. It is found that there are generically two critical radii at which changes of stability occur. In the case where the perturbation takes the form of a single zonal harmonic, only one of these radii is physical and is given by the ratio 2Lp/Lγ , where Lp is the hydraulic conductivity and Lγ is the Onsager coefficient related to changes in membrane area due to lipid accretion. The stability of such perturbations is related to the value of l corresponding to the particular zonal harmonic: those with lower l are more unstable than those with higher l. Possible extensions of the current work and the need for experimental input are discussed.

“…The principles of nonequilibrium thermodynamics originally proposed by Onsager (1931a,b) and later reformulated by Prigogine (1947, 1967), De Groot (1961), De Groot and Mazur (1962, Fitts (1962), Baranowski (1991), and Kondepudi and Prigogine (1998) state that the rate of lost work associated to entropy production per unit area due to any irreversible process is the scalar product (inner product) of steady state fluxes J i and generalized forces X i as shown below…”
