The Rheology and Performance of Geothermal Spring Water-Based Drilling Fluids
(Wiley-Hindawi, 2019)
In this study, the rheological properties and performances of mud prepared with geothermal spring water to be used by geothermal drilling operators were examined at ambient and elevated temperatures. In this context, mud ...
Usage of Olivine as Additive Material in Water-Based Drilling Muds
(Parlar Scientific Publications (P S P), 2019)
Drilling is one of the most common methods for the production of fossil fuels or geothermal energy. The success of drilling operations depends on various parameters. One of these parameters is drilling mud. Drilling mud ...
A Computer Program for Practical Semivariogram Modeling and Ordinary Kriging: A Case Study of Porosity Distribution in an Oil Field
(De Gruyter Poland SP Zoo, 2017)
In this study, firstly, a practical and educational geostatistical program (JeoStat) was developed, and then example analysis of porosity parameter distribution, using oilfield data, was presented. With this program, two ...
Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT)
(Elsevier, 2020)
In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a ...
A Comprehensive Study on Fuel Adulteration Sensing by Using Triple Ring Resonator Type Metamaterial
(Electrochemical Society Inc., 2019)
A novel shaped metamaterial sensor application which is designed to operate in X band is proposed. A new sample holder for easy operation is designed and placed just behind the proposed structure in X band. Since the ...
Effect of n-CaCO3 on fresh, hardened properties and acid resistance of granulated blast furnace slag added mortar
(Elsevier, 2020)
Nano size CaCO3 (n-CaCO3) particles were used as an additive into the Ground Granulated Blast Furnace Slag (GGBS) added mortar to investigate their effects on fresh, hardened properties and acid resistance. Setting time, ...
Synthesis of a Multifunctional Quinoxaline and Benzodithiophene Bearing Polymer and Its Electrochromic Device Applications
(Wiley-V C H Verlag Gmbh, 2020)
A quinoxaline (Qx) and benzodithiophene (BDT) comprising of random copolymers, namely poly(5-(6-(5-(4,8-bis((2-ethylhexyl)oxy)benzo[1,2-b:4,5-b ']dithiophen-2-yl)-4-(2-ethylhexyl)thiophen-2-yl)-4,8-bis ((2-ethylhexyl)oxy ...
Removal of Cr(VI) from aqueous solution by pyrolytic charcoals
(Editorial Board of New Carbon Materials, 2016)
Bio-chars produced by the pyrolysis of walnut shells at 450? (BC450) and theco-pyrolysis of walnut shells and 20 wt% tar sand (BCTS20)at the same temperature, were investigated as potential adsorbents for the removal of ...
Obtaining of modified bitumen with optimum quality through mixing of natural bitumen (gilsonite), bitumen and thinner oil
(Springer, 2015)
In this research the modified bitumen was obtained from natural bitumen (gilsonite), B160/220 and B50/70 bitumen and thinner oil in different adding amount by weight. Some engineering properties of these materials were ...
Investigation of Fly Ash Effect on Rheological and Filtration Properties of Drilling Muds
(Parlar Scientific Publications (PSP), 2018)
The aim of the present study is to improve rheological and filtration properties of water based drilling fluids by addition of fly ash and to investigate the physical and chemical properties of the additive and drilling ...
