Resumen
Detrended cross correlation analysis (DCCA) is used to identify and characterize correlated
data obtained in drilled oil wells. The investigation is focused on different petro-physical
measurements within the same well, and of the same measurement from two wells in the
same oil field. The evaluation of cross correlation exponents indicates if scaling properties
in two measurements are alike. The work considers also the values of cross correlated
coefficients, which provide an assessment on the local correlation between measurements.
The existence of several highly correlated events provides information on the continuity of
geological structures, including partial and global dislocations of deposited layers.
