Implication

Performance evaluation highlights gas injection improves oil recovery in Niger Delta reserves, suggesting effective strategies for heavy oil recovery.

Key Points

Gas injection with nitrogen significantly enhanced oil recovery by maintaining reservoir pressure and utilizing solution gas drive.
Nitrogen injection resulted in the highest oil recovery of 7.00 MMstb, compared to CO2 injection (6.87 MMstb) and chemical EOR methods.
A fully integrated reservoir model using numerical simulation ensured reliability, revealing polymer flooding's superior performance (6.10 MMstb).
Combining gas injection for pressure support and polymer flooding for mobility control optimizes recovery in moderately pressured heavy oil systems.
