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

Behrouz Harimi; Mohsen Masihi; Mohammad Hosein Ghazanfari

Volume 8, Issue 2 , Spring 2019, , Pages 73-91

http://dx.doi.org/10.22050/ijogst.2018.140366.1465

Abstract
  Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid ...  Read More

3. An Influence of Polymer-Alkaline and Nanoparticles as Chemical Additives on the Immiscible Displacement and Phase Relative Permeability

Elham Mortazavi; Mohsen Masihi; Mohammad Hosein Ghazanfari

Volume 5, Issue 3 , Summer 2016, , Pages 14-31

http://dx.doi.org/10.22050/ijogst.2016.38523

Abstract
  In this study, a chemical additive made by a combination of polymer, alkaline, and silica nanoparticles is used to control the oil recovery and relative permeability curves. Various parametersincluding the type and concentration of polymer, alkaline, and nanosilica particles have been studied.To evaluate ...  Read More

4. Comparison of Simulated Annealing, Genetic, and Tabu Search Algorithms for Fracture Network Modeling

Saeed Mahmoodpour; Mohsen Masihi; Sajjad Gholinejhad

Volume 4, Issue 2 , Spring 2015, , Pages 50-67

http://dx.doi.org/10.22050/ijogst.2015.9592

Abstract
  The mathematical modeling of fracture networks is critical for the exploration and development of natural resources. Fractures can help the production of petroleum, water, and geothermal energy. They also greatly influence the drainage and production of methane gas from coal beds. Orientation and spatial ...  Read More
