Abstract
  Asphaltene-induced formation damage is one of the complicated processes of permeability damage in porous media, particularly in the near-wellbore area. Asphaltene particles precipitate out of the bulk fluid phase during production as a consequence of pressure drop, which may reduce permeability owing ...  Read More

Iman Jafari; Mohsen Masihi; Masoud Nasiri Zarandi

Volume 8, Issue 3 , July 2019, , Pages 40-57

http://dx.doi.org/10.22050/ijogst.2018.118644.1434

Abstract
  Cocurrent spontaneous imbibition (COCSI) of an aqueous phase into matrix blocks arising from capillary forces is an important mechanism for petroleum recovery from fractured petroleum reservoirs. In this work, the modeling of countercurrent imbibition is used to develop the appropriate scaling equations. ...  Read More

Application of Nanoparticles for Chemical Enhanced Oil Recovery

Alimorad Rashidi; Alireza Solaimany Nazar; Hamideh Radnia

Volume 7, Issue 1 , January 2018, , Pages 1-19

http://dx.doi.org/10.22050/ijogst.2018.98264.1410

Abstract
  In this paper, the potentials of using particles, especially nanoparticles, in enhanced oil recovery is investigated. The effect of different nanoparticles on wettability alteration, which is an important method to increase oil recovery from oil-wet reservoirs, is reviewed. The effect of different kinds ...  Read More

An Experimental Study on Permeability Reduction Resulting from Mixed BaSO4, CaSO4, and SrSO4 Scale Deposition in Porous Media during Water Injection

Saeed Naseri; Jamshid Moghadasi; Mohammad Jamialahmadi

Volume 4, Issue 4 , October 2015, , Pages 33-49

http://dx.doi.org/10.22050/ijogst.2016.12478

Abstract
  Sulfate scale deposition (BaSO4, CaSO4, and SrSO4) is a common problem in oilfield operations around the world, which causes significant formation damage during production and injection activities. This paper presents the results of an experimental study on the permeability reduction of porous media ...  Read More
