Abdossamad Rastegar; Bagher Anvaripour; Nematollah Jaafarzadeh

Volume 5, Issue 1 , Winter 2016, Pages 1-12

http://dx.doi.org/10.22050/ijogst.2016.13825

Abstract
  In the present study, lightweight expanded clay aggregate (LECA) coated with iron oxide was investigated as a low cost sorbent to remove  from wastewater. Iron oxide coated LECA (IOCL) as a new sorbent was tested for its efficiency as  sorbent using operational parameters such as contact time, ...  Read More

3. Simulation and Assessment of Surfactant Injection in Fractured Reservoirs: A Sensitivity Analysis of some Uncertain Parameters

Mohammad Hasan Badizad; Ahmad Reza Zanganeh; Amir Hossein Saeedi Dehaghani

Volume 5, Issue 1 , Winter 2016, Pages 13-26

http://dx.doi.org/10.22050/ijogst.2016.13826

Abstract
  Fracture reservoirs contain most of the oil reserves of the Middle East. Such reservoirs are poorly understood and recovery from fractured reservoirs is typically lower than those from conventional reservoirs. Many efforts have been made to enhance the recovery and production potential of these reservoirs. ...  Read More

4. A Novel Integrated Approach to Oil Production Optimization and Limiting the Water Cut Using Intelligent Well Concept: Using Case Studies

Turaj Behrouz; Mohammad Reza Rasaei; Rahim Masoudi

Volume 5, Issue 1 , Winter 2016, Pages 27-41

http://dx.doi.org/10.22050/ijogst.2016.13827

Abstract
  Intelligent well technology has provided facility for real time production control through use of subsurface instrumentation. Early detection of water production allows for a prompt remedial action. Effective water control requires the appropriate performance of individual devices in wells on maintaining ...  Read More

5. Modeling and Simulation of Claus Unit Reaction Furnace

Maryam Pahlavan; Mohammad Ali Fanaei

Volume 5, Issue 1 , Winter 2016, Pages 42-52

http://dx.doi.org/10.22050/ijogst.2016.13828

Abstract
  Reaction furnace is the most important part of the Claus sulfur recovery unit and its performance has a significant impact on the process efficiency. Too many reactions happen in the furnace and their kinetics and mechanisms are not completely understood; therefore, modeling reaction furnace is difficult ...  Read More

6. Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems

Karim Salahshoor; Babak Roshanipour; Iman Karimi

Volume 5, Issue 1 , Winter 2016, Pages 53-64

http://dx.doi.org/10.22050/ijogst.2016.13829

Abstract
  The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based ...  Read More

7. Effects of Surface Treatment on Corrosion Resistance of 304L and 316L Stainless Steel Implants in Hank’s Solution

Saeid Ghanavati; Mohammad Reza Shishesaz; Mansoor Farzam; Iman Danaee

Volume 5, Issue 1 , Winter 2016, Pages 65-72

http://dx.doi.org/10.22050/ijogst.2016.13830

Abstract
  The enormous demands for metal implant have given rise to a search for cheap material with good bio-tolerability and resistance to corrosion. Although stainless steel has these properties and is widely used for this purpose, its long term application is still a concern. The corrosion resistance of stainless ...  Read More
