1. Comparing Two Methods of Neural Networks to Evaluate Dead Oil Viscosity

Meysam Dabiri-Atashbeyk; Mehdi Koolivand-salooki; Morteza Esfandyari; Mohsen Koulivand

Volume 7, Issue 1 , Winter 2018, , Pages 60-69

  Reservoir characterization and asset management require comprehensive information about formation fluids. In fact, it is not possible to find accurate solutions to many petroleum engineering problems without having accurate pressure-volume-temperature (PVT) data. Traditionally, fluid information has ...  Read More

2. An Efficient Method for Determining Capillary Pressure and Relative Permeability Curves from Spontaneous Imbibition Data

Mojtaba Ghaedi; Zoltán E. Heinemann; Mohsen Masihi; Mohammad Hossein Ghazanfari

Volume 4, Issue 3 , Summer 2015, , Pages 1-17

  In this paper, a very efficient method, called single matrix block analyzer (SMBA), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (SI) data. SMBA mimics realistically the SI tests by appropriate boundary conditions modeling. In the proposed ...  Read More

3. 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

  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

4. Preventing Instability Phenomenon in Gas-lift Optimization

Mohammad Reza Mahdiani; Ehsan Khamehchi

Volume 4, Issue 1 , Winter 2015, , Pages 49-65

  One of the problems that sometimes occur in gas allocation optimization is instability phenomenon. This phenomenon reduces the oil production and damages downhole and surface facilities. Different works have studied the stability and suggested some solutions to override it, but most of them (such as ...  Read More

5. Power Consumption Minimization of Khormoj Compressor Station

Javid Haddad; Reza Mosayebi Behbahani; Mohammadreza Shishesaz

Volume 3, Issue 2 , Spring 2014, , Pages 66-78

  Arguably, the natural gas transmission pipeline infrastructure in Iran represents one of the largest and most complex mechanical systems in the world. The optimization of large gas trunk lines known as IGAT results in reduced fuel consumption or higher capability and improves pipeline operation. In the ...  Read More

6. A New Approach to Measuring Cementation Factor by Using an Intelligent System

Hamid Heydari; Jamshid Moghadasi; Reza Motafakkerfard

Volume 2, Issue 4 , Autumn 2013, , Pages 39-53

  Cementation factor is a critical parameter, which affects water saturation calculation. In carbonate rocks, due to the sensitivity of this parameter to pore type, water saturation estimation has associated with high inaccuracy. Hence developing a reliable mathematical strategy to determine these properties ...  Read More
