... are generated from a generic reservoir model using commercial simulator. Various models of recovery factors and gas oil ratio are developed for different times (after 90 days, 1 year, 5 years, 10 years, 15 years and 20 years) and for a minimum economic rate (5 STB/ day). Multivariate regression was used...

... Abstract When the oil price is low, it is essential to optimize an EOR process in low-permeability reservoir, especially in unconventional shale oil reservoirs. Gas huff-n-puff, has shown to be an effective EOR method. This paper is to optimize this process to enhance oil recovery in shale oil...
