Estimation of rock mass rating values with geostatistical analysis
Özkan, Esma Selma; Erkayaoğlu, Mustafa; Department of Mining Engineering (2019)
The raw material of many goods, products, and equipment used by humankind on earth or even in space are obtained from extracted and enriched minerals from the surface or underground mines. A large proportion of the energy produced and used worldwide are derived from carbon-containing materials that are extracted from mining operations. This points out that the demand for these materials is not expected to decrease for human beings to sustain their existence on earth and may be in space. As this requirement ...
Investigation of the adsorption of dithiophosphate and dithiophosphinate on chalcopyrite as a function of pulp potential and pH
Güler, Taki; Hiçyılmaz, Cahit; Gökağaç, Gülsün; Department of Mining Engineering (2002)
Pulp potential and pH play important roles on flotation of sulphide ores. These parameters define the redox products formed on sulphide mineral surface. Therefore, it is essential to investigate electrochemical behaviour of sulphide minerals under different conditions. In this research, electrochemical behaviour of chalcopyrite from Artvin- Murgul deposit were investigated in the presence and absence of dithiophosphate (DTP) and dithiophosphinate (DTPI) by cyclic voltammetry and Diffuse Reflectance Infrared...
Planktonic foraminiferal biostratigraphy of the paleocene-eocene sequences in the western and central black sea region, Turkey
Güray, Alev; Altıner, Sevinç; Department of Geological Engineering (2014)
The Paleocene-Eocene sequences are widely distributed around onshore and offshore Black Sea. When the previous studies in the Turkish coasts of the Black Sea are considered, the deficiency of a detailed biostratigraphical framework attracts the attention. The taxonomy of the planktonic foraminifera and the benthic foraminifera assemblages are important for the establishment of the new biostratigraphical frame in the Paleocene-Eocene sequences of the Western and Central Black Sea regions. The Paleocene-Eocen...
Effects of nanoparticles on the performance of drilling fluids
Bal, Berk; Kök, Mustafa Verşan; Gücüyener, İsmail Hakkı; Department of Petroleum and Natural Gas Engineering (2017)
In this master thesis, effects of nanoparticles on the filtration and rheological properties of water-based drilling fluids are experimentally investigated. Four different silica nanoparticles are added into the lignosulfonate and bentonite based drilling fluids. By using data obtained at the end of this research, filtration and rheological properties of nanofluids are analyzed and compared with the base fluids at different temperatures. Two groups of experiments are conducted in this research. In the first...
Estimation of the formation temperature from the inlet and outlet mud temperatures while drilling geothermal formations
Tekin, Sema; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2010)
Formation temperature is an important parameter in geothermal drilling since it affects all the components of the system such as drilling fluid, drilling operations and equipment through mud temperatures. The main objective of this study is to estimate the formation temperatures of five geothermal wells in Germencik-Ömerbeyli geothermal field by using inlet and outlet mud temperatures obtained during drilling. For this purpose, GTEMP, a wellbore thermal simulation model is used to simulate the process of dr...
