Azadeh Mamghaderi; Behzad Rostami; Seyed Hamed Tabatabaie

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

Farhad Asgharyan; Mohammadreza Khosravi Nikou; Bagher Anvaripour; Iman Danaee

Volume 7, Issue 2 , Spring 2018, Pages 52-63

http://dx.doi.org/10.22050/ijogst.2018.65739

Abstract
  The present study is about the reduction of humic acids (HA) by electrocoagulation (EC) method. Undesirable color, odor, taste, reacting with chlorine to produce toxic materials in water, and making a complex with heavy metal ions are some unfavorable environmental consequences of HA. Platinum and graphite ...  Read More

5. An Investigation of Oil Spreading Coefficient in Carbonated Water+ Gas + Oil System: an Experimental Study in an Iranian Asphaltenic Oil Reservoir

Abdolah Golkari; Masoud Riazi; Amin Avazpour

Volume 7, Issue 2 , Spring 2018, Pages 64-78

http://dx.doi.org/10.22050/ijogst.2017.91564.1395

Abstract
  To provide supplementary oil recovery after the primary and secondary processes, enhanced oil recovery (EOR) techniques are introduced. Carbonated water injection (CWI) as an EOR method can improve sweep efficiency and the risk of gas leakage. On the other hand, the interfacial tension (IFT) is one of ...  Read More

6. Catalytic Oxidation of Carbon Monoxide by Cobalt Oxide Catalysts Supported on Oxidized-MWCNT

Mahnaz Pourkhalil; Saeideh Tasharrofi

Volume 7, Issue 2 , Spring 2018, Pages 79-90

http://dx.doi.org/10.22050/ijogst.2017.105780.1421

Abstract
  Cobalt oxide catalysts supported on oxidized multi-walled carbon nanotubes (MWCNT) for the low-temperature catalytic oxidation of carbon monoxide were prepared by an impregnation-ultrasound method. These catalysts were characterized by N2 adsorption/desorption, TEM, XRD, Raman, and H2-TPR methods. The ...  Read More
