Both porosity and permeability constitute the major parameters in core analysis. In this study, the variation of these two parameters along a sandstone core sample was investigated during formation damage. A water-based drilling fluid was dynamically circulated through the core sample for three different time intervals of 15 min, 45 min, and 60 min at 100 psi circulation pressure. The core sample was analyzed using x-ray digital radiography by sectional image approach. The differences in the porous media due to fines migration by drilling fluid were examined. Digital image subtraction method was applied by using an in-house simulator developed to run with MATLAB to determine porosity. The experimental results obtained by dynamic circulation and x-ray imaging were compared with the results obtained by using a numerical fines migration simulator. Consistent matches between the experimental and numerical results were observed indicating that porosity and permeability impairments with distance can be described accurately.

Investigation of structural, electronic and lattice dynamical properties of XNiH3 (X = Li, Na and K) perovskite type hydrides and their hydrogen storage applications Gencer, Ayşenur; Surucu, Gokhan (Elsevier BV, 2019-06-07) XNiH3 (X = Li, Na, and K) perovskite type hydrides have been studied by using Density Functional Theory (DFT) and these materials are found to be stable and synthesizable. The X-ray diffraction patterns have been obtained and they indicate that all materials have the polycrystalline structure. The electronic properties have been investigated and it has been found that these structures show metallic character. The Bader partial charge analysis has also been performed. In addition, the elastic constants have ...
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 ...
New method for investigation of parameters of real thermoelectric modules AHISKA, RAŞİT; Ahiska, K. (Elsevier BV, 2010-02-01) In the present study, a new method to investigate all output parameters of a thermoelectric module has been developed. The new method bases on the thermoemf measurement of a working module and the comparison of the results with those of classical methods. The new method is employed in investigation of the parameters of a standard thermoelectric module of Melcor with production code of CP1.0-127-05L. The theoretical results calculated by the means of new and classical methods for the parameters of an actual ...
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. ...
Enhancement of hydrogen storage properties of Ca3CH antiperovskite compound with hydrogen doping Gencer, Ayşenur; Surucu, Gokhan (Wiley, 2020-01-01) The doping effect of hydrogen on the Ca3CHx (x = 1, 4, 7, 9, and 10) antiperovskite compounds has been examined using density functional theory (DFT). The results of the structural optimizations show that all these compounds have negative formation energy implying the energetic stability and synthesizability. The band structures that are essential for the electronic properties have been determined along with the partial density of states (DOS) showing the metallic behavior of these compounds. In addition, t...
