Oil recovery by ionic surfactant and sweep efficiency study in sandstones
(Associação Brasileira de Pesquisa e Desenvolvimento em Petróleo e Gás, 2008)
In this work, we have investigated the oil recovery performance, adsorption, sweep and displacement efficiency by ionic surfactants. In the adsorption and recovery assays, a surfactant aqueous solution at a concentration ...
Estudo numérica do processo de deslocamento de fluidos em meio poroso heterogêneo usando o método de Lattice Boltzmann
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2018-04-13)
In the present work, the process of immiscible fluids displacement in a heterogeneous porous medium is numerically studied for the purpose of investigating the sweep efficiency during the oil recovery process. The objective ...
SPEED AND ROTATION VARIATIONS IN GATHERING COFFEE MACHINE
(Univ Federal Uberlandia, 2020-01-01)
The mechanized harvesting operation of coffee sweep from ground have a great importance, due the value of the coffee that was lost by the harvest process, as well as the breakdown of the cycle of pests that can damage the ...
Modelling of earthquake-induced pounding between adjacent structures with a non-smooth contact dynamics method
(2021)
This article presents the kinematic analysis of two adjacent structures with pounding using the framework of finite element dynamic analysis and a non-smooth contact dynamics (NSCD) method for treating contact-impact. The ...
Experimental study of the effect of carbonated brine on wettability and oil displacement for EOR application in the Brazilian Pre-Salt reservoirs
(Taylor & FrancisBrasilNúcleo Interdisciplinar de Dinâmica dos Fluidos, 2019)
Análise de parâmetros operacionais da injeção contínua de vapor adaptado ao método sagd em reservatórios de petróleo pesado no nordeste brasileiro
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Petróleo, 2017)
The world scenario in the oil segment estimates a large oil reserve to be explored, about 1.7 trillion barrels, in 2015. In Brazil, more specifically, in the Northeast, there are large reserves of heavy oil, which needs ...

Optimal Production Strategies for the Development of Mature Oil Fields through Polymer Flooding
(American Chemical Society, 2021-07)
Polymer flooding is one of the most extensively applied techniques for enhanced oil recovery (EOR) that relies on increasing the injected fluid viscosity by adding polymers in different concentrations. The aim is to improve ...
Avaliação da influência da vazão de injeção de sistemas microemulsionados na recuperação avançada de petróleo aplicada a reservatórios areníticos
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de petróleo, 2018-12-03)
Oil is a very exploited energy source, still accounting for 50% of the world's energy capacity, so there is a great demand for hydrocarbons in reservoirs hundreds of meters below the surface for exploitation. However, ...
Método dos volumes finitos Central-Upwind em malhas não estruturadas: aplicação à simulação numérica do transporte de polímeros em meios porosos
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2020-06-12)
Polymer flooding in oil reservoirs has been one of the enhanced oil recovery (EOR)
methods most applied in the last decades. The main objective of the technique is to
increase the viscosity of the water, adjusting the ...
