In some oil reservoirs, injecting water into the formation can help increase oil recovery. Understanding the rheological behavior of Water/Oil (W/O) emulsions is essential in EOR techniques like water flooding, as it affects the displacement efficiency and the ability of the injected water to move through the reservoir. The stability of W/O emulsions is critical in preventing phase separation, which can lead to pipeline blockages, equipment fouling, and product quality issues. Rheological characteristics of emulsions refer to their flow behavior and viscosity under different shear rates and temperatures. This rheological investigation examines how viscosity changes with temperature, shear rate, and water content. Water-in-oil emulsions were created by mixing light paraffin crude oil with different volume fractions of water (20, 30, and 40%). This observation suggests that shear stress and temperature influence emulsion flow behavior by affecting the arrangement and interaction of water and oil droplets inside the emulsion. Emulsions containing natural surfactants derived from renewable sources exhibit improved stability because they reduce interfacial tension and form a protective barrier around the dispersed water droplets. The stability of the emulsion was evaluated by keeping an eye on its propensity to phase separation with a change in droplet size over time.
