Micromodel flooding is a cost-effective method to investigate enhanced oil recovery. In this study, we
apply Lauryl Betaine as an amphoteric surfactant to the injected fluids into the micromodel and compare
the results with conventional EOR techniques such as water flooding, solvent flooding, and microemulsion flooding. First, we determined the optimal flow rate of injected fluid into the micromodel to
represent fluid flow in the formation. Next, we did water flooding with varying salinities. Next, we did
solvent flooding with two different ratios of solvents. Condensate and hexane are the solvents we
applied. Next, we did surfactant flooding using Lauryl Betaine. Surfactant flooding tests are conducted
using different salinity and surfactant concentration (Cs). Finally, we did microemulsion flooding. The
results show that surfactant flooding at high salinity using Lauryl Betaine leads to highest oil recovery
among all tested EOR methods. Besides, the results indicate that addition of Lauryl Betaine to the injected
brine leads to higher breakthrough time (BT).
