On the basis of detailed petrographic analysis of samples from two wells cored through the Permian Murteree and Roseneath shales (Dirkala-02 and Moomba-46 wells), four lithofacies have been recognized. Core descriptions focused on texture, lithology, bioturbation and sedimentary structure. Petrographic and geochemical analyses of core samples are used to develop the electrofacies. Electrofacies modelling is used to develop a conceptual geological model of the lithofacies in areas without cored wells with the help of conventional well log data. Electrofacies were used to extend the facies interpretations for Roseneath and Murteree shales across the basin into areas where core was not available for study.
