Abstract

In the current study, multivariate analysis methods of time series are used to simplify the search for correlations among different oil wells. Gamma ray log of potassium, thorium, and uranium isotopes of three wells in Ras Fanar oil field in Gulf of Suez, Egypt are taken as examples. we suppose gamma log as a time series, where time is replaced by depth. Autocorrelation and principal component analysis were applied to such supposed time series to extract stratigraphic structure of the fields under study. The uranium gamma log was the common factor between the three wells and anti-correlated to depth, while thorium log depends on the depth but with less conclusive results. The results clearly show the applicability to model petro-physical data using multivariate analysis.
