Implication

Comparative evaluation of methane, foam, and gravity-assisted injection improves oil recovery in depleted oil fields, suggesting optimal EOR strategies.

Key Points

The aim is to evaluate the efficacy of methane flooding, foam injection, and gravity-assisted methane injection for enhanced oil recovery in depleted oil fields.
Developed a calibrated 3D reservoir simulation model using a full-physics black-oil approach.
Conducted history matching to ensure model accuracy for the three EOR scenarios.
Analyzed production behavior, cumulative oil, and pressure distribution for each injection strategy.
Methane injection achieved the highest cumulative oil recovery at 4.19 million stb, with a recovery factor increase to 38.4%.
Foam injection resulted in a cumulative oil recovery of 3.74 million stb, showing a 15% enhancement in sweep efficiency.
Gravity-assisted methane injection recovered 3.62 million stb, improving vertical sweep by 12% and delaying gas override.
