Our slim-tube setup is crucial for assessing oil displacement efficiency in enhanced oil recovery (EOR) studies. This one-dimensional porous media setup spans 60 feet in length, with an internal diameter of 0.124 inches and a wall thickness of 0.063 inches. The bead pack within the slim tube has a porosity of 35% and a permeability of 3.8 Darcy.

Typically employed to measure the efficiency of gas injections—such as CO₂ and enriched gas—under varying pressures, the slim-tube setup operates effectively at pressures up to 10,000 psia. This experimental setup provides invaluable insights into the behavior and effectiveness of gas EOR methods. The setup is placed in an oven to control the displacement temperature, which represents the target formation’s temperature.
