Abstract Water-Alternating-Gas (WAG) injection is a relatively mature oil recovery technique
in hydrocarbon reservoirs that has long attracted the interest of the oil and gas industry due …

Nitrogen (N 2) is widely used in oil and gas industry. We report two new efficient closed-form
representations for the molar entropy and Gibbs free energy of pure gaseous substances. A …

In this study, the potential of cyclic CO 2 injection process was examined for CO 2 storage
and enhanced oil recovery. For this purpose, a detailed phase behavior study on the light …

Carbon capture, storage, and utilization technologies target a reduction in net CO2
emissions to mitigate greenhouse gas effects. The largest such projects worldwide involve …

Based on the modified Rosen-Morse oscillator in the description of the internal vibration of a
molecule, we propose an explicit representation of molar enthalpy for gaseous diatomic …

A design of experiment was used to create oil rim models from a wider range of reservoir,
operational and reservoir architecture parameters. A response surface model was …

The primary recovery of conventional heavy oil (with viscosity< 150 mPa s) in deep
reservoirs often has a low recovery factor (RF) and high-pressure drawdown. It is important …

Performance of cyclic CO2 injection as an enhanced oil recovery (EOR) technique in a light
crude oil system was experimentally investigated. Series of cyclic CO2 injection tests were …

The efficiency of CO 2 water-alternating-gas (WAG) flooding is highly limited in low-
permeability heavy oil reservoirs due to the viscosifying action of W/O emulsification and …

Abstract Immiscible Water Alternating Gas (IWAG) is an EOR process whereby water and
immiscible gas are alternately injected into a reservoir to provide better sweep efficiency and …
