Ali Moazami Goodarzi; Arman Darvish Sarvestani; Ali Hadipour

Volume 9, Issue 1 , Winter 2020, , Pages 33-46

http://dx.doi.org/10.22050/ijogst.2019.153012.1480

Abstract
  Nowadays, the increasing demand for energy in the world is one of the main concerns for energy supply. In fact, the required energy can be obtained by increasing the production rate of fossil fuels such as oil and natural gas. However, improving the efficiency of the equipment and facilities might have ...  Read More

Shahin Kord; Omid Ourahmadi; Arman Namaee-Ghasemi

Volume 9, Issue 1 , Winter 2020, , Pages 94-111

http://dx.doi.org/10.22050/ijogst.2018.108293.1423

Abstract
  Production strategy from a hydrocarbon reservoir plays an important role in optimal field development in the sense of maximizing oil recovery and economic profits. To this end, self-adapting optimization algorithms are necessary due to the great number of variables and the excessive time required for ...  Read More

http://dx.doi.org/10.22050/ijogst.2017.44344

Abstract
  The removal of sulfur compounds from petroleum is extremely necessary for industrial and environmental reasons. Sulfur in transportation fuels is a major air pollution source. In this work, the efficiency of nanostructured Ni-clinoptilolite adsorbent was investigated in the removal of sulfur from gas ...  Read More

6. 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
