Uso do GPR na caracterização da pluma de contaminação gerada por hidrocarbonetos a partir de um posto de combustível na Praia de Búzios/RN
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2009-06-30)
This work is the application of geophysical methods, using the Ground Penetrating Radar (GPR), with the objective of survey in a subsurface plume of contamination caused by a disabled gas station. The gas station is located ...
Estudo comparativo da injeção contínua de vapor entre reservatórios de óleos pesados e extrapesados
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Petróleo, 2016-11-29)
The oil industry looks always for higher oil production from a reservoir, setting this as objective, there are constantly research for new ways to how extract the oil from subsurface. However, some reservoirs have too ...
Inversão sísmica das formas de onda baseada em otimização híbrida
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2020-02-19)
The Oil today is a vital resource for society. Besides being a great player in the energy

However, the increase of its production ...
Adicionando informação a priori ao formalismo do FWI através da entropia relativa
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2021-07-16)
Full waveform inversion is a technique used to obtain the subsurface velocity model
with high accuracy. In the oil industry (mainly in reservoir characterization), it is common to use well information as priori information ...
Um estudo de estratégias de inversão de dados sísmicos via inversão da forma de onda completa no domínio da frequência
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2019-12-27)
Full-Waveform Inversion is a powerful seismic imaging technique capable of recovering highresolution subsurface models from observed data. This inversion is a nonlinear problem
formulated as a local optimization problem ...

With the advancement of hydrocarbon exploration, the oil industry has been searching
for ways to minimize exploratory risks, with one of these ways being the improvement
of the used tools. There are three steps in this ...
Desenvolvimento morfo-estrutural do Terraço Ceará: o Alto Marginal Oeste da Zona de Fratura Romanche
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2018-02-26)
A Marginal Ridge is a prominent morph-structural feature associated with an extremity of a Fracture Zone. The evolution of rifted and sheared margin segments might control the formation of marginal ridges. The Ceará Terrace ...
Fraturas e halos de subsidência em torno de dolinas, Semiárido do Brasil
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2019-09-30)
Carbonate rocks are recognized for their great heterogeneity and for the
presence of structures associated with dissolution. This is very important in
fractured regions, since fractures can induce dissolution processes. ...
Hydrography and circulation in the Northern Gulf of California during winter of 1994-1995
(2006)
Hydrographic and current measurements in the Northern Gulf of California from December 1994 through March 1995 show conditions that are markedly different from those accepted as typical for winter. A rapid subsurface warm ...
Geophysical exploration to estimate conductivity and permittivity model of an excavated soil block
(2014)
An electrical model for a real stratified soil block is proposed in this paper. The model is suitable to estimate the physical properties of electrical conductivity and permittivity, as well as the thickness of each of the ...
