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

http://dx.doi.org/10.22050/ijogst.2017.80561.1388

Abstract
  The oilfield water in the Upper Sandstone Member of the Zubair reservoir (Barriemian-Hauterivian) at Rumaila North Oil Field was investigated for the interpretation of salinity and geochemical evolution of brine compositions. The interaction of the oilfield water with reservoir rock resulted in a brine ...  Read More

Volume 7, Issue 1 , Winter 2018, Pages 40-59

http://dx.doi.org/10.22050/ijogst.2017.78181.1383

Abstract
  Gas condensate reservoirs are characterized by a distinctive retrograde behavior and potential for condensate drop out during production and sampling. Efficient modeling of gas condensate reservoir requires careful phase behavior studies of samples collected prior to and during the production life of ...  Read More

Meysam Dabiri-Atashbeyk; Mehdi Koolivand-salooki; Morteza Esfandyari; Mohsen Koulivand

Volume 7, Issue 1 , Winter 2018, Pages 60-69

http://dx.doi.org/10.22050/ijogst.2017.70576.1373

Abstract
  Reservoir characterization and asset management require comprehensive information about formation fluids. In fact, it is not possible to find accurate solutions to many petroleum engineering problems without having accurate pressure-volume-temperature (PVT) data. Traditionally, fluid information has ...  Read More

5. Artificial Intelligence for Inferential Control of Crude Oil Stripping Process

Mehdi Ebnali; Mehdi Shahbazian; Houshang Jazayerirad

Volume 7, Issue 1 , Winter 2018, Pages 70-92

http://dx.doi.org/10.22050/ijogst.2017.54928.1337

Abstract
  Stripper columns are used for sweetening crude oil, and they must hold product hydrogen sulfide content as near the set points as possible in the faces of upsets. Since product    quality cannot be measured easily and economically online, the control of product quality is often achieved ...  Read More

6. A Numerical Study on Using Air Cooler Heat Exchanger for Low Grade Energy Recovery from Exhaust Flue Gas in Natural Gas Pressure Reduction Stations

Mansoor Naderi; Ghasem Zargar; Ebrahim Khalili

Volume 7, Issue 1 , Winter 2018, Pages 93-109

http://dx.doi.org/10.22050/ijogst.2018.55741

Abstract
  Heat EXchangers (HEX) that are used in City Gate Station (CGS) systems are modeled numerically to recover the exhaust waste heat. It was tried to find the best viscous model to obtain results in accordance with experimental results and to change the heat exchanger design. This HEX is used for recovering ...  Read More
