Estudo técnico-econômico comparativo da injeção de água, glicerina e polímero em um reservatório com características do nordeste brasileiro. 2020. 124f.

This kind of situation puts this productive chain in a vigilant state and its own search for survival implicates in a need of new ways its activities remain economically viable. Therefore, the innovation has been a new goal inside the methodology that new eyes must go for the optimization of processes searching for the way out for this difficulty. Methods that recover petroleum increase the oil recovery factor associated with a field, but can be extremely burdensome and end up with a self-sabotage. With this in mind new methods or those who has been bypassed at first, exactly for these more traditional methods has had an advantage of the once lived scenario. The Glycerin injection, little observed during the golden years, proves itself a clear alternative of lowering the costs of the production once, compared to the polymer injection, this fluid has a price below its aggregated value and can be found in different forms, brute and purified, opening, even more, its range of applications. Comparing those, more advanced techniques with the most simple and pioneer one, the water injection, thought computational simulation, can be noted that, technically, an advantage in the application of more recently developed methods. With this, this work was developed in a search for the characteristics of each technic and its associated return with the use of mathematical modelling, the software of CMG. The final argument in the comparation of projects comes to the profitability associated to each one of them and, in this context the NPValue shows itself as a solution to this doubt. Comparing the water, polymer and glycerin injection was possible to see how the consolidation of the more traditional technics and how each fluid affects the operation financially. For that reason, for a reservoir with the Brazilian northeast characteristics, where can be found a good portion of the onshore industry, and taking as technical and economical conclusions can be, through computational fluid dynamics, solved the question about the future of petroleum industry.Acesso AbertoInjeção de GlicerinaInjeção de PolímeroSimulação ComputacionalmasterThesis
