In this research, two groups of experiments were conducted to investigate the effects of silica (SiO2) nanoparticles on the filtration and rheological properties of water-based drilling fluids. In the first group, bentonite, chrome-free lignosulfonate (CFL) and carboxymethyl cellulose (CMC) were used in different concentrations to obtain base fluids. Nanofluids were prepared by adding 0.5 g of four different silica nanoparticles into these drilling fluids. Comparison of rheological properties, fluid loss amounts and mud cake thicknesses were performed at two different temperatures (25 degrees C and 49 degrees C). It was concluded that all of the nanoparticles reduced the filtration efficiency of bentonite muds. On the contrary, a reduction in fluid loss was observed for some lignosulfonate muds containing nanoparticle. However, no significant change in mud cake thickness and rheological properties was seen for both drilling fluids.

Effect of Polymers on the Rheological Properties of KCl Polymer Type Drilling Fluid Kök, Mustafa Verşan (2005-05-01) In the course of this research, the effect of two polymers (xanthan gum and polyanionic cellulose) on the rheological properties of KCl/polymer type drilling fluids was investigated. Non-Newtonian drilling fluids are conventionally characterized by rheological models (Bingham Plastic, Power Law, Casson, Herchel-Bulkley and Robertson-Stiff). In this research, forty-five KCl/polymer data sets of varying compositions are prepared. Polymer addition to the system has affected the model and caused a variation of ...
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...
Effects of walnut shells on the rheological properties of water-based drilling fluids Iscan, A.G.; Kök, Mustafa Verşan (2007-08-01) In this research, three different water-based drilling fluids were prepared according to American Petroleum Institute (API) standards, and effects of walnut shells on the rheological properties of the samples were studied. The walnut shells of 2-, 4-, and 6-mm samples and their equal weight mixtures of 2-4 mm and 4 6 mm were added to the drilling fluid samples in different concentrations. The aim of this study is to determine the optimum walnut shell size, concentration and polymer concentration to minimize...
Effect of thermal treatments and palladium loading an hydrogen sorption characteristics of single-walled carbon nanotubes KOCABAŞ, SEFA; KOPAÇ, TÜRKAN; DOĞU, GÜLŞEN; Doğu, Timur (2008-03-01) The effects of thermal treatments and palladium loading on sorption characteristics of single-walled carbon nanotube (SWCNT) samples were investigated. The thermal treatment experiments were carried out in a temperature range of 300-800 degrees C. The sorption characteristics of nitrogen and hydrogen on the original, heat treated and the palladium loaded samples were investigated. Analyzing the nitrogen adsorption isotherms on these samples at 77.4 K, the highest specific surface area of 2230 m(2)/g was obt...
Effect of solvent choice on cellulose acetate membrane fabrication by phase inversion and deacetylation by alkaline hydrolysis Tekin, Fatma Seden; Çulfaz Emecen, Pınar Zeynep; Department of Chemical Engineering (2022-8) In this study, the effect of solvent choice on cellulose acetate (CA) membrane morphology and performance was investigated to relate this to the thermodynamics and kinetics of phase inversion. Three different solvent systems were used, which are dimethyl sulfoxide (DMSO), the mixture of DMSO: acetone (DA) and DMSO: acetic acid (DHAc) in the ratio of 1:1. Water was used as non-solvent. Acetone and acetic acid were chosen due to their similar solvent quality for cellulose acetate based on Hansen solubility pa...
