Journal ArticleDOI
Numerical Modeling of Diffusion in Fractured Media for Gas-Injection and -Recycling Schemes
Hussein Hoteit,Abbas Firoozabadi +1 more
TL;DR: In this paper, a consistent model to incorporate physical diffusion of multicomponent mixtures for gas-injection schemes in fractured reservoirs is presented, for the first time, which can affect significantly the efficiency of gas injection in oil reservoirs and recycling in gas/condensate reservoirs.
Journal ArticleDOI
Modeling interfacial tension and minimum miscibility pressure in paraffin-nitrogen systems: Application to gas injection processes
TL;DR: In this article, a simple-to-use algorithm was proposed to calculate the minimum miscibility pressure (MMP) in normal alkane/nitrogen systems based on the measurements with vanishing interfacial tension (VIT) technique, which predicts the MMP with high accuracy.
Journal ArticleDOI
A study on the minimum miscibility pressure for miscible flooding systems
TL;DR: In this article, the minimum misibility pressure of a Chinese reservoir crude oil injected with pure and impure CO 2 have been measured in a RUSKA slim tube apparatus, and new correlations were proposed for CO 2 -flooding and lean natural gas-floodings systems, respectively.
Journal ArticleDOI
A rigorous approach to predict nitrogen-crude oil minimum miscibility pressure of pure and nitrogen mixtures
TL;DR: In this paper, a simple correlation for accurate determination of the minimum miscibility pressure (MMP) of N 2 -crude oil, based on the explicit functionality of reservoir temperature as well as thermodynamic properties of crude oil and injection gas, is presented.

Determination of minimum miscibility pressure in N2–crude oil system: A robust compositional model
Abdolhossein Hemmati-Sarapardeh,Erfan Mohagheghian,Mohammad Fathinasab,Amir H. Mohammadi,Amir H. Mohammadi +4 more
TL;DR: In this paper, a least square support vector machine (LSSVM) optimized with coupled simulated annealing (CSA) was proposed to develop a reliable and robust model for the prediction of MMP of pure/impure N2-crude oil.
