Student thesis: Master's Thesis


The future development of Vietnam energy strategies focusing on the renewable energy in order to reduce dependence on fossil fuel energy source as well as to meet the target of mitigating global warming effect by reducing greenhouse gases emission which also contribute to guarantee energy security and sustainable socioeconomic development Considering above concerns the geothermal energy is one of the most promising renewable resources There are some geothermal potential area in Vietnam such as South Central North West North Central North East and North Plain Binh Chau is one of the most geothermal potential area in South Central Vietnam Binh Chau geothermal field has highly productive fracture fault zone (eruptive rhyolite) which contains the hot water that reach 82 ℃ around the depth about 15-35 m underground The heat sources at the bottom supplies the heat through the fractured fault zone The heat sources is about 160 oC according to geochemical calculation This geothermal reservoir is also supplied by surface stream as a ground water Numerical simulation is the most common method to evaluate the geothermal system throughout the development In this study numerical models are built to simulate the fluid flow and heat transfer through the geothermal system Then a series of sensitivity analysis and optimization of the heat production is done accordingly This study was successful in establishing a conceptual model from the geological researches hydrological reports and surface hot springs history data observation wells data; the calibration of the conceptual model by natural state conditions and matches with the temperature profile from hot spring wells; the uncertainty analysis of expected energy capacity calculated most likely about 5 2 MWe suggesting that building a geothermal power plant in Binh Chau area is economical choice
