In the Niger Delta, low oil recovery rates less than 30% results mainly due to production problems such as water coning, wax deposition and high gas/oil ratios. Meanwhile, remaining becomes a good candidate for EOR methods CO2 injection, polymer foam in-situ combustion steam injection. But it stands, practice of these known enhanced is scarce in Nigeria’s Oil Gas industry. However, this project aimed at evaluating application injection an method sandstone reservoir exploring possible improvement Delta. The was carried out using two cases. Case 1, synthetic model built with static modeling software, later imported dynamic software simulated mimic process while 2 real life aquifer fully populated necessary fluid properties history. From obtained indices, field recovery, etc. were compared gas flooding process. For flooding, significant increase reduction ratio produced observed 2, rate, cumulative production, cut reduced also observed. economic viability both cases investigated some indicators. Improved displacement efficiency resulting into increased recoverable reserves, subsequently total has been achieved by injection.   Key words: Chemical, foam, modeling, production.
