Acesso em:.https://repositorio.ufpa.br/handle/2011/11555This work deals with the implementation of numerical 2.5-D Marine Controlled Source Electromagnetic (MCSEM) modeling applied to hydrocarbon exploration in stratified environment. In the mathematical formulation the fields were assumed to have two parts: the primary and the secondary ones. The first uses of Schelkunoff potentials in its formulation and they were employed in both (x; ky; z; !) and (x; y; z; !) domains. The secondary fields are solved in the frequency domain space (x; ky; z) by finite element method. With a Inverse Fourier transform, the secondary fields were taken in the domain (x; y; z). From the total field, we can show the influence of an oil reservoir in a stratified environment and its sensitivity to the lateral extension of a hydrocarbon reservoir.Acesso AbertoProspecção magnéticaMétodo dos elementos finitosPetróleo - ProspecçãoGeofísica aplicadaMétodos eletromagnéticosElementos finitosMarine controlled source electromagneticExploração de óleoÁguas profundasElectromagnetic methodsApplied geophysicsFinite element methodExploration of oilDeep waterDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA
