Characterization of light diesel fraction obtained from upgraded heavy oil
(Egyptian Petroleum Research Institute, 2018)
In this study, the role of a low-cost catalyst (activated molasses soil) over the hydrocarbon distribution of the light diesel (or distillate) fraction of the pre-upgraded heavy crude oil (Bati Raman) was examined in detail. ...
Production of an insulation material from carpet and boron wastes
(General Directorate of Mineral Research and Exploration (MTA), 2016)
Buildings are large consumers of energy in all countries. In regions with harsh climatic conditions, a substantial share of energy goes to heat and cool buildings. This paper reports an investigation of the insulation ...
An Artificial Neural Network Approach for the Prediction of Water-Based Drilling Fluid Rheological Behaviour
(2018)
It is well known that high temperatures, which change the rheological properties of the drillingfluid and can frequently cause problems in deep wells, is a major problem during drilling. Theimportance of the estimation and ...
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 ...
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 ...
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 ...
Exergetic Simulation and Performance Analysis of the Effect of Flow Patterns in PEMFCs
(Int Center Applied Thermodynamics, 2019)
In this study, 6 different novel flow channels of the "proton exchange membrane" (PEM) type fuel cells were designed and modeled, while evaluations were conducted on three-dimensional channels of various designs using ...
Development of GPS and GIS-Based Monitoring System for the Quality of Excavated Coal
(Technical University of Kosice, faculty Berg, 2018)
Because of the advancement of geospatial technologies such as GIS and GPS integration, many mining companies have started to use the technology for mine planning, analysis and management. In this context, this study focuses ...
Comparison of stable isotope values of Quaternary calcretes from Adana and Mersin provinces: implications on controlling factors
(Scientific Technical Research Council Turkey-Tubitak, 2019)
Calcretes are widespread in Adana and Mersin provinces and form under different morphologies. Most calcrete profiles comprise a hard laminated crust/hardpan at the top, gradually intergrading into the nodular and/or ...
Investigation of the effects on rheological and filtration properties of water-based drilling mud of boron minerals: An experimental study
(Pamukkale University, 2019)
The aim of this study is to determine the effect on the rheological and filtration properties of water based drilling fluid of boron minerals. For this purpose, water-based drilling mud was prepared and borax (Na2B4O7.10H2O) ...
