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 corresponding to those processes was performed. The results of this parametric study showed that these controllable parameters have a significant influence on CO2 sequestration process and should be well optimized for effective sequestration processes in a deep saline aquifer. The present study indicated that vertical to horizontal permeability ratio (k(v)/k(h)) and initial pressure conditions were the most dominating parameters affecting the free CO2 saturation at the injection well block in each layer of the aquifer; whereas, free CO2 saturation level in the middle and bottom layers was strongly affected by CO2 injection rate. This can be attributed to the fact that an increase in k(v)/k(h) ratio caused an increase in free CO2 saturation level in top layer; whereas, free CO2 saturation level decreased with an increase in k(v)/k(h) ratio in the middle and bottom layers due to the high tendency of free CO2 to rise up.

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 ...
Modeling of CO2 storage in an oil reservoir
Gumrah, F.; Dulger, M.; Gunaydin, D.; Senel, O. (Informa UK Limited, 2008-01-01)
This study provides an overview for the carbon dioxide sequestration process in an oil reservoir by using the software CMG's GEM. Different scenarios are applied for the oil reservoir description. Firstly, a single layered reservoir is considered and simulation studies are performed, as this reservoir is homogeneous, heterogeneous and fractured. Secondly, a multi-layered reservoir is examined. In the second case, a heterogeneous system and a heterogeneous system composed of homogenous layers are selected. F...
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...
Diffusive and Convective Mechanisms during CO2 Sequestration in Aquifers
Ozgur, E.; Gumrah, F. (Informa UK Limited, 2009-01-01)
CO2 emissions originated from industrial sources can be captured, transported, and stored in depleted gas/oil fields and deep saline aquifers. The transport mechanisms, occurred during CO2 sequestration in deep saline aquifers, are examined in this study. After injecting CO2 until the tolerable pressure for the aquifer is reached, the wells are closed and CO2 is deposited as free gas and soluble gas in water under the sealing rock. During injection and waiting periods, the concentration profile of CO2 withi...
A Rheological Characterization and Parametric Analysis of a Bentonite Sample
Kök, Mustafa Verşan (Informa UK Limited, 2011-01-01)
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, ...
