This review paper extends comprehensive study on implementing enhanced recovery schemes in mature oil and gas fields, by discussing the existing EOR techniques that were and are currently utilized by many oil giants. The study discusses the kind of tertiary oil recovery techniques are employed in a mature reservoir to get the residual oil recovered, or any hydrocarbon accumulations that were not recovered by conventional primary and secondary oil recovery techniques. A numerical model using Thermal simulator - STARS of CMG Suite 2015 was developed to study the influence of steam flooding in a heavy oil reservoir. The study was carried out in 3 main phases to understand the steam flooding process efficiently along by understanding the screening criteria and the effects of various parameters on the production performance of reservoirs, which includes the effects of injection rates, the kind of composition of injected steam and well pattern and spacing.
