2. Prevention of Biofouling in Hydrocarbons by Antimicrobial Vessel and Pipeline Coating for Cost Savings and an Increase in Safety and Reliability

Maximilian Lackner; Josef-Peter Guggenbichler

Volume 2, Issue 2 , Spring 2013, Pages 1-7

http://dx.doi.org/10.22050/ijogst.2013.3532

Abstract
  Hydrocarbons are prone to bacterial and fungal contamination. Bacteria and fungi live and proliferate in water droplets within the fuels and on surfaces surrounding them. This can cause corrosion in oil exploration and production, clogging of fuel lines in aviation and higher emissions in diesel combustion ...  Read More

3. Delineating Hydrocarbon Bearing Zones Using Elastic Impedance Inversion: A Persian Gulf Example

Haleh Karbalaali; Seyed Reza Shadizadeh; Mohammad Ali Riahi

Volume 2, Issue 2 , Spring 2013, Pages 8-19

http://dx.doi.org/10.22050/ijogst.2013.3534

Abstract
  Reservoir characterization plays an important role in different parts of an industrial project. The results from a reservoir characterization study give insight into rock and fluid properties which can optimize the choice of drilling locations and reduce risk and uncertainty. Delineating hydrocarbon ...  Read More

4. Application of Homotopy Perturbation Method to One-dimensional Transient Single-phase EM Heating Model

Hossein Fazeli; Shahin Kord

Volume 2, Issue 2 , Spring 2013, Pages 20-33

http://dx.doi.org/10.22050/ijogst.2013.3535

Abstract
  Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, ...  Read More

5. Gas-liquid Relative Permeability Estimation in 2D Porous Media by Lattice Boltzmann Method: Low Viscosity Ratio 2D LBM Relative Permeability

Sadegh Mahmoudi; Abdonabi Hashemi; Shahin Kord

Volume 2, Issue 2 , Spring 2013, Pages 34-49

http://dx.doi.org/10.22050/ijogst.2013.3536

Abstract
  This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary conditions ...  Read More

6. CFD Simulation of Dimethyl Ether Synthesis from Methanol in an Adiabatic Fixed-bed Reactor

Mohammad Golshadi; Reza Mosayebi Behbahani; Mohammad Reza Irani

Volume 2, Issue 2 , Spring 2013, Pages 50-64

http://dx.doi.org/10.22050/ijogst.2013.3537

Abstract
  A computational fluid dynamic (CFD) study of methanol (MeOH) to dimethyl ether (DME) process in an adiabatic fixed-bed reactor is presented. One of the methods of industrial DME production is the catalytic dehydration of MeOH. Kinetic model was derived based on Bercic rate. The parameters of this equation ...  Read More

7. Failure Investigation of Hydrogen Blistering on Low-strength Carbon Steel

Elahe Shekari; Mohammad Reza Shishesaz; Gholamreza Rashed; Mansoor Farzam; E Khayer

Volume 2, Issue 2 , Spring 2013, Pages 65-76

http://dx.doi.org/10.22050/ijogst.2013.3538

Abstract
  The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical ...  Read More
