Modeling the Behavior of CH۲TCH۳ Tracer for Optimizing Enhanced Oil Recovery Using ECLIPSE Simulator

In the oil and gas industry, the use of radioactive tracers is one of the effective tools for analyzing fluid flow and evaluating the behavior of hydrocarbon reservoirs. These methods provide valuable information about fluid transport, swept pore volume, and the hydrodynamic connectivity between injection and production wells, which are crucial for optimizing reservoir management and designing enhanced oil recovery projects. In this study, the behavior of the radioactive tracer CH₂TCH۳ was simulated and analyzed in an oil reservoir using the ECLIPSE simulator. The tracer was injected into the reservoir through injection well I, and its response was evaluated in two production wells, P۱ and P۲. By analyzing the tracer curve over time, parameters such as the swept pore volume in the gas phase, gas flow velocity in the reservoir, and the hydrodynamic connectivity between the injection and production wells were calculated. The results indicated that production well P۱ exhibited the highest swept pore volume and tracer recovery, demonstrating a strong and direct connection between injection well I and production well Pl. These findings provide critical insights into gas transport and fluid flow in the reservoir and, in addition to enhancing reservoir management, offer a robust foundation for optimizing the design of enhanced oil recovery projects.
