Thankyou very much!
Applying for a master's degree in Civil Engineering
I am applying for a master's program in Civil Engineering at the Yonsei University. I already look for the Department's research area and I am highly interested to join the Geo-Energy and Geo-Materials Laboratory in Yonsei University. This laboratory focuses on Geo-energy and Geo-materials including the CO2 sequestration storage. CO2 sequestration storage is a promising technology for mitigating increasing concentrations of carbon dioxide in the atmosphere. I have a high interest to do research about identifying suitable reservoir conditions for effective and safe CO2 sequestration storage.
In my master's program I plan to conduct a research about the pore-scale model of the CO2 sequestration storage. Understanding in pore-scale is crucial to estimating critical CO2 characteristics in the reservoir, including storage capacity, leakage risk, and storage efficiency (Yamabe et al., 2015). The study of rock microstructure can be utilized to predict the macroscopic rocks properties of the reservoir (Kameda, 2004; Fredrich, DiGiovanni and Noble, 2006; Khokhlov et al., 2008) such as porosity, permeability, and statistical properties defined by the local porosity theory. The detail of the research I want to conduct is about the modelling of the pore-scale model. Modeling of rock microstructure in pore-scale is very helpful in analyzing physical properties of the reservoir. It will provide more detail information about physical properties of reservoir usually gained from geophysical explorations and measurements.
My bachelor study in Physics has prepared to me with a strong foundation about the mathematical skill, analytical skill, computational skill and also the knowledge of the subject of the research as I mention above as well because in my bachelor study I did my research in the Rock Physics and Porous Medium Physics Research Division. The topic of my bachelor thesis is about the analysis of the complexity of the porous medium (in pore-scale). Meandering parameter is a new complexity parameter that I submitted in my bachelor thesis. Meandering parameter is a complexity parameter that could explain the complexity of the porous medium with how long and how winding the porous medium path is. In my research, I also developed computer code (MATLAB) that could calculate the Tortuosity and the Meandering Parameter of a two and three dimensional porous medium model. The code calculate the Meandering Parameter and Tortuosity of porous medium with its streamline that has been generated after the velocity map of that porous medium is obtained using Lattice Boltzmann fluid simulation methods. I have also presented my research in a conference and publish 2 proceeding paper, the first one is about the meandering parameter above and the second one is about the Analysis of the effect of grain size and model on the parameters of porous rock model structure. For those reason above, I have totally provided my self to perform well in my future study at the Yonsei University.
Currently there are several methods existed for generating 3D pore scale of porous models using computer modeling , e.g., the ellipsoid model that the shape and the orientation can be varied easily by arranging major and minor axes, and normally they are constructed randomly (appropriate apparently for clean sandstones with smooth surfaces) (Latief and Fauzi, 2012). There is also non-spherical polyhedron grain model that the idea is to reshape sedimented spherical grains where each spherical grain is surrounded by an ellipsoid defined by three axes lengths chosen randomly between predefined minimum and maximum axis length(Pilotti, 2000; Øren et al., 2002). Those models are greatly valuable to predict some of the physical properties.
Based on background and general description above, the objectives of my future research are characterize the definitions of effective and safe CO2 storage, develop 3 dimensional rock model with several computational modeling, develop the most suitable 3 dimensional rock model for CO2 storage reservoir, and comparing the most suitable 3 dimensional rock model to into a real rock from reservoir in order to identifying suitable reservoir conditions for effective and safe CO2 storage. My plan about the methodogy of this research are literature study, computer modelling, computer simulation, scanning a reservoir sample with micro CT-Scan, computing rock parameters and also evaluate, conclude, and suggest for future development.
I contend that this research will be valuable in the future considering that the issue of the increasing concentrations of CO2 in the atmosphere. In order to identify a suitable reservoir for effective and safe CO2 storage, a suitable three dimensional digital rock model is needed because it could ease the creation of condition that is used to classify the rocks physical property and understanding the CO2 characteristics in the reservoir.

Hessel, more than 90% of this essay is not geared towards the goal of study and study plan of the KGSP program. You are expected to make a thesis proposal for the goal of study and study plan essay. You are not going to enumerate your research background and interests. You must revise this essay. The parts of the essay that you can use to develop a proper thesis proposal is as follows:
The objectives of my future research are characterize the definitions of effective and safe CO2 storage...safe CO2 storage.
Literature study, computer modelling, computer simulation, scanning a reservoir sample with micro CT-Scan, computing rock parameters and also evaluate, conclude, and suggest for future development.
You will need to develop a clear thesis statement prior to presenting your objectives though. Then add information as to how the university will be able to help you complete this research through certain aspects that can change in the future. The whole presentation can actually change once you are already a student. It all depends upon whether you still have the same research desire by that time. Added information can include possible internship participation and hands-on fieldwork ( if applicable). Don't forget to include your expected research outcome if you have one.
