| Zusammenfassung |
| We employ Detrended Fluctuation Analysis
(DFA) technique to investigate spatial properties of an oil
reservoir. This reservoir is situated at Bacia de Namorados, RJ,
Brazil. The data corresponds to well logs of the following
geophysical quantities: sonic, gamma ray, density, porosity and
electrical resistivity, measured in 56 wells. We tested the
hypothesis of constructing spatial models using data from
fluctuation analysis over well logs. To verify this hypothesis we
compare the matrix of distances among well logs with the differences
among DFA-exponents of geophysical quantities using spatial
correlation function and Mantel test. Our data analysis suggests
that sonic profile is a good candidate to represent spatial
structures. Then, we apply the clustering analysis technique to the
sonic profile to identify these spatial patterns. In addition we
use the Mantel test to search for correlation among
DFA-exponents of geophysical quantities. |
