Abstract
  Water can contain microorganisms and cause deposition and corrosion in cooling tower systems. Therefore, the water treatment of cooling towers is essential. Various biocides are used to remove bacteria and disinfect the water of cooling towers, and the most commonly used are sodium hypochlorite and chlorine ...  Read More

Volume 10, Issue 2 , April 2021, Pages 12-27

http://dx.doi.org/10.22050/ijogst.2021.269283.1581

Abstract
  Wellbore stability is one of the challenges in the drilling industry. Shale formation is one of the most problematic rocks during drilling because the rock has very low permeability and tiny pores (nanometers). This study assesses the viability of the alumina nanoparticles (Al2O3) in water-based mud. ...  Read More

Volume 10, Issue 2 , April 2021, Pages 51-61

http://dx.doi.org/10.22050/ijogst.2021.276176.1586

Abstract
  In current work, perturbed chain-statistical associating fluid theory (PC-SAFT) equation of state (EoS) together with the reaction equilibrium thermodynamic model (RETM) was employed to correlate H2S solubility in three carboxylate ionic liquids including [emim][Ace], [bmim][Ace], and [hmim][Ace]. The ...  Read More

Mehdi Rezaei Abiz; Saeid Norouzi Apourvari; Saeed Jafari; Mahin Schaffie

Volume 10, Issue 2 , April 2021, Pages 90-106

http://dx.doi.org/10.22050/ijogst.2021.276860.1587

Abstract
  Although experimental studies confirmed the effectiveness of nanoparticles in enhanced oil recovery applications, no comprehensive investigation has been carried out to reveal the effect of different subsurface factors on this improvement. Proper application of nanoparticles mainly depends on their ability ...  Read More

Research Paper Petroleum Engineering – Production
The Role of Effective Thickness of the Asmari Formation Zones on Oil Production

Behzad Orangii; Mohammad Ali Riahi

Volume 10, Issue 2 , April 2021, Pages 107-119

http://dx.doi.org/10.22050/ijogst.2021.278551.1588

Abstract
  This paper investigates the role of the adequate thickness of the Asmari reservoir formation zones on oil production in one of the Iranian carbonate oil fields. Adequate thickness is a term that includes the total gross thickness of rocks by lithofacies for a selected wellbore. The lithology of the Asmari ...  Read More
