“…It makes the oleic phase at least partially miscible with water. Or the aqueous phase at least partially miscible with petroleum 19 . The three pseudo-component system is represented on a ternary diagram ( Figure 1) where the chemical component is located on top, the water on bottom left and the petroleum on bottom right.…”

“…Therefore, a binodal curve divides the triangle in two zones: the miscible zone on top and the immiscible two-phase zone on bottom. So as to describe the phase diagram by a mathematical model, a binodal curve made up of two straight lines has been proposed 10,19 (Figure 1.1 -1.10). …”

“…In the immiscible zone, tie-lines (dashed lines) indicate the coexistence of two phases (see, for example, Figure 1 The miscibilization of oil into the aqueous phase is called "solubilization", and the miscibilization of chemical and water into the oil phase is called "swelling" 10,11,19 . In the immiscible zone, as the chemical concentration increases, tielines get increasingly shorter.…”

TX 75083-3836 U.S.A., fax 01-972-952-9435. AbstractTo mobilize the oil trapped after secondary recovery by waterflooding, chemicals (surfactants, alcohols, alkalis, etc.) are injected into the reservoir. Chemical flooding has two main effects: 1) the interfacial tension between oil and water phases is decreased, and 2) these phases become partially miscible. A numerical model is proposed to analyze those effects on oil recovery.

This is the second of two joint papers which study the influence of several physical properties on the transport phenomena in chemical flooding. To that aim, we use a previously reported ternary two-phase model into which representative physical properties have been incorporated as concentration-dependent functions. Physical properties such as phase behavior, interfacial tensions, residual saturations, relative permeabilities, phase viscosities and wettability have been analyzed in the first paper.In this paper, we discuss the influence of capillary pressure, adsorption of the chemical component onto the rock and dispersion. Although arising from different phenomenological sources, these transport mechanisms show some similar effects on concentration profiles and on oil recovery. They are studied for systems with different phase behavior. A numerical analysis is also presented in order to determine the relevance of the number of grid blocks taken in the discretization of the differential equations. This numerical analysis provides useful guidelines for the selection of the appropriate numerical grid in each type of displacement.
