Majid Alipour; Bahram Alizadeh; Ali Chehrazi

Volume 6, Issue 4 , Autumn 2017, Pages 1-17

http://dx.doi.org/10.22050/ijogst.2017.53898

Abstract
  Commercial hydrocarbon discoveries in the Cretaceous of the southern Persian Gulf basin provide direct evidence that there is an effective petroleum system associated with the Cretaceous series. The revised models of thermal maturity in this region are needed to investigate lateral and stratigraphic ...  Read More

2. A Kinetic Investigation into the In Situ Combustion Reactions of Iranian Heavy Oil from Kuh-E-Mond Reservoir

Milad Karimian; Mahin Schaffie; Mohammad Hassan Fazaelipoor

Volume 6, Issue 4 , Autumn 2017, Pages 18-32

http://dx.doi.org/10.22050/ijogst.2017.82422.1390

Abstract
  An efficient design of in situ combustion depends on accurate kinetic modeling of the crude oil oxidation. The kinetic triplet of the oxidation reactions of a heavy oil sample was investigated. Once the kinetic triplet is known, the kinetic equation would be deconvolved. The crude oil sample was obtained ...  Read More

3. A Comparative Study of the Neural Network, Fuzzy Logic, and Nero-fuzzy Systems in Seismic Reservoir Characterization: An Example from Arab (Surmeh) Reservoir as an Iranian Gas Field, Persian Gulf Basin

Reza Mohebian; Mohammad Ali Riahi; Ali Kadkhodaie-Ilkhchi

Volume 6, Issue 4 , Autumn 2017, Pages 33-55

http://dx.doi.org/10.22050/ijogst.2017.53907

Abstract
  Intelligent reservoir characterization using seismic attributes and hydraulic flow units has a vital role in the description of oil and gas traps. The predicted model allows an accurate understanding of the reservoir quality, especially at the un-cored well location. This study was conducted in two major ...  Read More

4. Effect of Repeated Repair Metal Inert Gas Welding on Microstructural Properties, Corrosion Resistance, and Wear Behavior of 5083-H116 Aluminum Alloy

Mohammad Reza Zarghamian; Mansoor Farzam; Iman D Danaee; Hadi Eskandari

Volume 6, Issue 4 , Autumn 2017, Pages 51-63

http://dx.doi.org/10.22050/ijogst.2017.53910

Abstract
  The effect of repeated repair welding, shielded with argon, on microstructural properties, corrosion resistance, and dry sliding wear behavior of aluminum alloy 5083/H116 were investigated. Samples were welded by metal inert gas welding method. 100% argon was used to protect fusion zone. Aluminum alloy ...  Read More

5. An Influence of Trench Formation on Steel Catenary Risers Based on a Hysteretic Nonlinear Seabed Model

Reza Siahtiri; Abdolrahim Taheri

Volume 6, Issue 4 , Autumn 2017, Pages 64-79

http://dx.doi.org/10.22050/ijogst.2017.53912

Abstract
  A steel catenary riser (SCR) attached to a floating platform at its upper end encounters fluctuations in and near its touchdown zone (TDZ), which causes the interaction with the seabed. Subsea surveys and the analysis of SCR’s indicated that the greatest stress and highest damage occurred near ...  Read More

6. Mathematical Modeling and Numerical Simulation of CO2 Removal by Using Hollow Fiber Membrane Contactors

Mohammad Mesbah; Masumeh Jafari; Ebrahim Soroush; Shohreh Shahsavari

Volume 6, Issue 4 , Autumn 2017, Pages 80-96

http://dx.doi.org/10.22050/ijogst.2017.53913

Abstract
  Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations ...  Read More
