2. An Evaluation of Rock Integrity and Fault Reactivation in the Cap Rock and Reservoir Rock Due to Pressure Variations

Mohammad Abdideh; Yaghob Hamid

Volume 8, Issue 3 , Summer 2019, Pages 18-39

http://dx.doi.org/10.22050/ijogst.2019.136347.1462

Abstract
  Cap rocks are dams which can prevent the upward movement of hydrocarbons. They have disparities and weaknesses including discontinuities, crushed areas, and faults. Gas injection is an effective mechanism for oil recovery and pore pressure. With increasing pore pressure, normal stress is reduced, and ...  Read More

3. An Analytical Solution for One-dimensional Horizontal Imbibition in a Cocurrent Flow

Iman Jafari; Mohsen Masihi; Masoud Nasiri Zarandi

Volume 8, Issue 3 , Summer 2019, Pages 40-57

http://dx.doi.org/10.22050/ijogst.2018.118644.1434

Abstract
  Cocurrent spontaneous imbibition (COCSI) of an aqueous phase into matrix blocks arising from capillary forces is an important mechanism for petroleum recovery from fractured petroleum reservoirs. In this work, the modeling of countercurrent imbibition is used to develop the appropriate scaling equations. ...  Read More

5. The Selection of Amine Solvent in Gas Treating Process Considering Physical and Process Criteria Using Multiple Criteria Decision-making Techniques: A Case Study of Ilam Gas Treating Company

Masoud Seidi; Mohsen Khezeli; Behrouz Bayati; Esmaeil Najafi

Volume 8, Issue 3 , Summer 2019, Pages 73-88

http://dx.doi.org/10.22050/ijogst.2017.93209.1396

Abstract
  In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria ...  Read More

7. Thermodynamic and Kinetic Investigations of Corrosion Inhibition Behavior of 2-MBT on Steel at a pH of 8

Hojatallah Koraee; Hadi Eskandari; Iman Danaee

Volume 8, Issue 3 , Summer 2019, Pages 101-112

http://dx.doi.org/10.22050/ijogst.2018.55732

Abstract
  Corrosion results in hazardous and expensive damage to pipelines, vehicles, water and wastewater systems, and even home appliances. One of the most extensively practical methods for protecting metals and alloys against corrosion is to use organic inhibitors. The inhibition capability of 2-Mercaptobenzothiazole ...  Read More
