http://dx.doi.org/10.22050/ijogst.2019.146641.1473

Abstract
  This paper addressed the application of new hydrophobic synthesized calcium oxide (CaO) and silicon dioxide (SiO2) nanofluids to low permeability carbonate porous media. Crude oil and plugs were selected from one of oil reservoirs in the west of Iran. The main goal of this paper is comparing the results ...  Read More

Volume 7, Issue 2 , Spring 2018, , Pages 14-34

http://dx.doi.org/10.22050/ijogst.2018.106164.1425

Abstract
  In this study, direct laboratory measurements of unsteady-state imbibition test are used in a new approach to obtain relative permeability curves with no predetermined functionality assumptions. Four equations of continuity, Darcy’s law, cumulative oil production, and water fractional flow are ...  Read More

http://dx.doi.org/10.22050/ijogst.2013.3536

Abstract
  This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary conditions ...  Read More
