During the initial stage of this research, properties (x-ray, chemical analysis, swelling test, cation exchange capacity, and amount of clay) of bentonite samples were determined. The concentration effect on the rheological properties of bentonite suspension was determined at six different concentrations (20, 22.5, 24, 26, 28, and 30 gr/350 ml). Fann viscometer dial readings were measured at ten varying rates of shear600, 300, 200, 100, 60, 30, 20, 10, 6, and 3 rpm. A three-parameter Robertson-Stiff model, describing the flow of non-Newtonian fluid by mathematical equations in terms of shear rate and shear stress, were studied; parametric analysis was also performed.

An experimental investigation on the chemical stability of selected formation and determination of the proper type of water-base drilling fluids. Part 2. Test results Erkekol, Selcuk; Gucuyener, I. Hakki; Kök, Mustafa Verşan (Informa UK Limited, 2006-07-01) The objective of this study was to select the proper drilling fluid type and composition for drilling stable holes through the problems of the selected formations. This study was performed on shale samples taken from 10 wells in which hole instability was encountered to various extents during drilling the Germav formation. Both ionic and polymer inhibitions were utilized in formulating the proper drilling for the Germav formation. Ionic inhibition was obtained using KCl and NaCl. Polyanionic polymer (Pac-L)...
Parametric Study of Carbon Dioxide Sequestration in Deep Saline Aquifers Basbug, B.; Gumrah, F. (Informa UK Limited, 2009-01-01) CO2 sequestration in a deep saline aquifer was simulated using a compositional commercial simulator based on a single-well aquifer model, which was developed to analyze the injection and storage process of CO2 under supercritical and gaseous conditions for long periods of time. The influence of controlling parameters including vertical to horizontal permeability ratio, aquifer pressure, injection rate on the isothermal injection, and sequestration processes were investigated and the sensitivity analysis cor...
Characterization of lignocellulose biomass and model compounds by thermogravimetry Kök, Mustafa Verşan (Informa UK Limited, 2017-01-01) In this research, combustion characteristics of lignocellulose biomass (hazelnut shell) and three main components (cellulose, hemicellulose, and lignin) were investigated using thermogravimetry (TGA-DTG) technique at different heating rates. The ignition, peak, burn-out temperatures, and the heat liberation of lignocellulose biomass and three main components were also measured. Two different model-free kinetic methods, known as Ozawa-Flynn-Wall (OFW) and Kissinger-Akahira-Sunose (KAS), were used in order to...
Analytical and Numerical Modeling of CO2 Sequestration in Deep Saline Aquifers Ozgur, E.; Gumrah, F. (Informa UK Limited, 2010-01-01) The analytical and numerical modeling of CO2 sequestration in deep saline aquifers having different rock and fluid properties was studied under diffusion and convection mechanisms. In a diffusion dominated system, an aquifer with 100 m thickness was saturated with CO2 after 10,000,000 years. It was much earlier in a convective dominant system. In the diffusion process, the dissolution of CO2 in aquifer increased with porosity increase; however, in a convection dominant process dissolution of CO2 in aquifer ...
Development and characterization of layered Li(NixMnyCo1-x-y)O-2 cathode materials for lithium ion batteries Piskin, Berke; Aydınol, Mehmet Kadri (Elsevier BV, 2016-06-22) The structure of the layered Li(NixMnyCo1-x-y)O-2 in different amounts of x and y ranging between 0.2 and 0.6, have been synthesized and investigated by powder X-ray diffraction and electron microscopy techniques. In the current work spray pyrolysis was used to obtain spherical fine-sized morphology followed by heat treatment to obtain better electrochemical activity. The precursor powders were prepared using aqueous solution via spray pyrolysis. Synthesized samples were then heat treated at 850 degrees C. ...
