Volume 11, Issue 4 , October 2022, , Pages 27-50

https://doi.org/10.22050/ijogst.2023.355345.1651

Abstract
  An essential transport characteristic that links a substance's molar (mass) flux to its concentration gradient is the molecular diffusion coefficient. For modeling and performance forecasting of solvent-aided recovery processes of heavy oils such as VAPEX and SAGD; a reliable and accurate estimation ...  Read More

Volume 11, Issue 3 , July 2022, , Pages 67-79

https://doi.org/10.22050/ijogst.2023.368047.1659

Abstract
  This research aims to investigate the effect of microwaves on the physical and chemical properties of heavy crude oil in the presence of different minerals. In this regard, the physical and chemical changes of the oil and rock powder (sand and carbonate) mixture are investigated by microwave radiation. ...  Read More

An Experimental Study of CO2-low Salinity Water Alternating Gas Injection in Sandstone Heavy Oil Reservoirs

Hadi Zolfaghari; Alireza Zebarjadi; Omid Shahrokhi; Mohammad Hosein Ghazanfari

Volume 2, Issue 3 , July 2013, , Pages 37-47

https://doi.org/10.22050/ijogst.2013.3643

Abstract
  Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on ...  Read More
