RESUMO

Logistic regression models were generated starting from lithofacies described in cores and in well logs for two wells of Campos Basin. The main objective was verify the applicability of the technique in reservoir geology. The models were used to estimate the occurrence of reservoir facies in the wells. Results obtained were compared to the results of a previous discriminant analysis with the objective of determinate the accuracy of the two techniques as tools to estimate reservoir facies. Although discriminant analysis resulted more accurate in the estimate of reservoir facies, the use of logistic regression should not be discarded. Its independence of the normal distribution hypothesis make this technique, at least in theory more robust than the discrirninant analysis
