GASFLOOD-Core flood system for EOR by gas injection


The GASFLOOD is a fully automated, modular core flooding system built specifically to evaluate the efficiency of enhanced oil recovery by means of miscible or immiscible gas injection. The versatile system performs water flooding, gas flooding and WAG (water-alternating-gas) flooding. By virtue of the unsteady state method, the apparatus determines not only gas and liquid relative permeabilities but also residual oil saturation, post-water flood displacement efficiency, incremental oil recovery and water production as a function of gas injection. The device is also compatible with carbon dioxide (CO2). Optionally, the core holder can be positioned vertically to study the gravity segregation effect. The results from such studies are useful in optimizing gas injection and WAG schemes.
