Reza Behnood; Bagher Anvaripour; Nematollah Jaafarzade Haghighi Fard; Masoumeh Farasati

Volume 2, Issue 4 , October 2013, Pages 1-11

  In last decades, oil spill pollution has become an important issue of concern due to its serious environmental impacts; therefore, necessary actions should be taken to prevent or reduce these types of pollution and their environmental consequences. Natural organic sorbents are emerging as proper choices ...  Read More

Estimation of Flow Zone Indicator Distribution by Using Seismic Data: A Case Study from a Central Iranian Oilfield

Mahdi Rastegarnia; Ali Kadkhodaie

Volume 2, Issue 4 , October 2013, Pages 12-25

  Flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. Usually, a correct description of the lateral variations of reservoir is associated with uncertainties. From this point of view, the well data alone does not cover reservoir properties. Because ...  Read More

Adoptive Control of Well Drilling Systems

Karim Salahshoor; Behnam Lotfi

Volume 2, Issue 4 , October 2013, Pages 26-38

  Control of well drilling operations poses a challenging issue to be tackled. The loss of well control could lead to the occurrence of blowout as a severe threat, involving the risk of human lives and environmental and economic consequences. Conventional proportional-integral (PI) controller is a common ...  Read More

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

Hamid Heydari; Jamshid Moghadasi; Reza Motafakkerfard

Volume 2, Issue 4 , October 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

An Experimental Study of Adsorption Breakthrough Curves for CO2/CH4 Separation in a Fixed Bed of Nanoporous Shaped Copper Trimesate Metal Organic Framework

Tahereh Asadi; Mohammadreza Ehsani

Volume 2, Issue 4 , October 2013, Pages 54-66

  Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped ...  Read More

DME Synthesis over MSU-S Catalyst through Methanol Dehydration Reaction

Hamed Rashidi; Touba Hamoule; Mohammad Reza Khosravi Nikou; Ahmad Shariati

Volume 2, Issue 4 , October 2013, Pages 67-73

  MSU-S mesoporous catalyst with [SiO2]/[Al2O3] ratio of 55 was synthesized using tetrapropylammonium hydroxide (TPAOH) as a structure directing agent and hexadecyltrimethylammonium bromide (CTAB) as a surfactant. The catalytic activity of the calcined sample was evaluated for the dehydration of methanol ...  Read More
