My desicion..............Please read it, I would appreciate if someone can correct it. As result of a highly competitive globalized world, graduating with a Master's degree has always represented a goal that I hope to reach. Moreover, "X" is a country which economy depends heavily on energy resources as petroleum. Owing to this, X needs people and technologies that can face the issues and new challenges of today. This is one of the major reasons I would like to build a career in the Hydrocarbon exploration field, because I know it is a field which a low number of professional in the area and Even though in "X" exists similar programs, when I read the structure of those offered by the universities in "Y", I noticed that there are topics that are not covered in "X". During my time in university I studied several geosciences disciplines such as Gravity Method, Seismology, Magnetic Method, Quantum Geophysics and Data processing, which were my favorites in college and are the basis in the Hydrocarbon Exploration process. My interest in these particular areas, also was aroused during my last year in college when I was on an internship with the Exploration department of "H". While there, I was in touch with a lot of geosciences information. This was influential in determining my dissertation topic, which I ultimately undertook in an exploration field topic, specifically on the Analysis of the Simultaneous Seismic Inversion. I made my decisions about the universities I would like to study a master degree based in some university rankings published by several sites as Times Higher Education World University Rankings and QS World University Rankings My first option is the Exploration MSc, which is taught in the School of Earth and Environment at the University of K, and according to the QS World University Rankings 2019 it is in the Top 20 in the world for Earth and Marine Sciences department. My second options is the Exploration MSc, at the university of A which according to the Times Higher Education World University Ranking 2020 is in the top 3 of Universities in "Y". And my third option is the Exploration MSc at the University of L, this university is ranked in the top 30 in "Y" according to the QS World University Ranking 2019. In addition, the international reputation of excellence in these fields of the colleges I chose, attracts a huge variety of students, providing me the opportunity to meet and work with many like minded individuals from different nationalities around the world.
