Application Of Nano Fluids In Changing Reservoir Rock And Fluid Properties For Enhanced Oil Recovery, Mohammad Ehtemam Haghighi Jan 2014

Application Of Nano Fluids In Changing Reservoir Rock And Fluid Properties For Enhanced Oil Recovery, Mohammad Ehtemam Haghighi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In conventional oil reservoirs after drilling a well, the hydrocarbon starts to produce by the natural force of the reservoir. After a period of production the reservoir energy declines and the secondary recovery methods are used to keep the production rate constant. The most common secondary method is water flooding in which by injecting water into the reservoir, trapped oil is pushed toward the producing wells. Water flooding is not a long term method for producing oil and as soon as the water finds its path to the producers, water cut goes up and injection is not economical anymore. Therefore …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Constitutional stability is usually perceived as an invaluable asset in democratic regimes. Constitutional amendments become suspicious when they occur too often, particularly in countries newly engaged in the democratic process. This dissertation argues that recent constitutional amendments in democratizing Francophone West African countries are not necessarily made to advance democracy or the rule of law. Instead, they are designed to reinforce the political agenda of incumbent power-holders. Using a case study of three Francophone African countries (Benin, Burkina Faso, and Senegal), I try to understand why there are so many constitutional amendments in so short a period of time in …
