Amir Gharavi; Mohamed Hassan; Hesam Zarehparvar Ghoochaninejad; John Fianu; Michael Kenomore; Amjad Shah; James Buick

Volume 9, Issue 2 , April 2020, Pages 1-12

  Since the development bloom in unconventional reservoirs in North America, total organic carbon (TOC) has become a more essential parameter, as the indicator of the efficiency of these reservoirs. In this paper, by using conventional well logs and NMR log data, the TOC content of an unconventional reservoir ...  Read More

A New Methodology to Define Net Pay Zone in Gas Reservoirs

Mehdi Qassamipour; Elnaz Khodapanah; Seyyed Alireza Tabatabaei-Nezhad

Volume 9, Issue 2 , April 2020, Pages 13-30

  Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. ...  Read More

Managed Pressure Drilling Using Integrated Process Control

Mahdi Imanian; Mahdi Karbasian; Aazam Ghassemi

Volume 9, Issue 2 , April 2020, Pages 31-60

  Control of wellbore pressure during drilling operations has always been important in the oil industry as this can prevent the possibility of well blowout. The present research employs a combination of automatic process control and statistical process control for the first time for the identification, ...  Read More

Application of Decline Curve Analysis for Estimating Different Properties of Closed Fractured Reservoirs for Vertical Wells

Amin Daryasafar; Mohammad FathiNasab; Giovanni Da Prat; Riyaz Kharrat

Volume 9, Issue 2 , April 2020, Pages 61-80

  In this paper, decline curve analysis is used for estimating different parameters of bounded naturally fractured reservoirs. This analysis technique is based on rate transient technique, and it is shown that if production rate is plotted against time on a semi-log graph, straight lines are obtained that ...  Read More

Experimental and Theoretical Investigation of Gelation Time of Nanostructured Polymer Gels by Central Composite Approach

Mohsen Seidmohammadi; Eghbal Sahraei; Behrouz Bayati

Volume 9, Issue 2 , April 2020, Pages 81-92

  Currently available polymers as a component of in-situ gels are unsuitable for treating high-temperature/high-salinity reservoirs due to their chemical and thermal degradation. In this study, a new copolymer-based gel system including high molecular weight nanostructured polymers (NSPs) was developed ...  Read More

Effect of Graphene Oxide Decorated With Synthesized Nano-CeO2 on Barrier Properties of Epoxy Anticorrosion Coatings

Zeinab Nassaj; Fatemeh Ravari; Iman Danaee

Volume 9, Issue 2 , April 2020, Pages 119-135

  In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed ...  Read More
