Immiscible flooding
Witrynaimmiscible: [adjective] incapable of mixing or attaining homogeneity. Witryna19 lut 2024 · The choice of whether the CO 2 should be miscible or immiscible is based on many factors mainly the reservoir fluid properties, including oil viscosity, molecular weight (MW), API gravity, and composition, and reservoir rock properties, including pay zone depth, thickness, and mineralogy.

Witrynaof a miscible gas into a reservoir (also called miscible flooding) is a process whereby a gas is injected to reduce the interfacial tension between the oil and water in the reservoir, allowing for increased displacement of the oil and to increase pressure in the reservoir. The most common miscible gas used in EOR is carbon dioxide (CO 2). WitrynaIn this paper, effluent data from laboratory experiments are compared with analytical composition routes and profiles for three-phase partially miscible flow of three-component mixtures.

In practice, solvents for first-contactmiscibility are … Miscible flooding. Miscible injection is a proven, economically viable process that significantly increases oil recovery from many different types of reservoirs. Most miscible flooding projects use CO 2 or nitrogen as solvents to increase oil recovery, but other injectants are sometimes used. This page provides … Zobacz więcej To put miscible flooding into perspective, it is instructive to compare the performance of a miscible flood to that of a waterflood. Although it is impossible to define a "typical" flood, the simplistic example shown in Fig. … Zobacz więcej Three solvent-injection strategies commonly used in commercial miscible-flooding applications are slug injection, water-alternating … Zobacz więcej True miscible displacement implies that injected and displaced phases mix in all proportions without forming interfaces or two phases. The single-phase condition also implies that the solvent eventually displaces all … Zobacz więcej The two major factors that affect the performance of a miscible flood are oil-displacement efficiency at the pore level and sweep efficiency on the field scale.
