Previous issue date: 2014-12-17 / Esta pesquisa tem como objetivo verificar se ? poss?vel construir padr?es
espaciais em reservat?rios de petr?leo, usando expoentes de DFA (Detrended
Fluctuation Analysis) dos diferentes perfis geol?gicos como: s?nico, densidade,
porosidade, resistividade e raios gama. Fizeram parte da amostra 54 po?os de
petr?leo do campo de Namorado, localizados na bacia de Campos, no estado
do Rio de Janeiro, Brasil. Com o intuito de verificar a correla??o linear,
constru?ram-se matrizes de dist?ncias entre os po?os e matrizes de diferen?as
entre os DFA dos po?os, comparadas duas a duas e utilizado como m?todo
estat?stico o teste de Mantel. A hip?tese nula consiste em afirmar que n?o
existe correla??o linear entre as estruturas espaciais formadas pelas matrizes
de dist?ncias euclidianas e das diferen?as dos expoentes de DFA dos perfis
geol?gicos. Os perfis s?nicos (p=0,18) e da densidade (p=0,26) foram os que
revelaram uma tend?ncia ? correla??o ou correla??o fraca. Estudo
complementar, utilizando o contour plot, mostra os padr?es s?nicos e da
densidade compat?veis com presen?a de correla??o espacial, corroborando os
revelados pelo teste de Mantel / This research aims to set whether is possible to build spatial patterns over oil
fields using DFA (Detrended Fluctuation Analysis) of the following well logs:
sonic, density, porosity, resistivity and gamma ray. It was employed in the
analysis a set of 54 well logs from the oil field of Campos dos Namorados, RJ,
Brazil. To check for spatial correlation, it was employed the Mantel test between
the matrix of geographic distance and the matrix of the difference of DFA
exponents of the well logs. The null hypothesis assumes the absence of spatial
structures that means no correlation between the matrix of Euclidean distance
and the matrix of DFA differences. Our analysis indicate that the sonic (p=0.18)
and the density (p=0.26) were the profiles that show tendency to correlation, or
weak correlation. A complementary analysis using contour plot also has
suggested that the sonic and the density are the most suitable with geophysical
quantities for the construction of spatial structures corroborating the results of
Mantel test
