ABSTRACT
Our study has been carried out to develop models for predicting mechanical behaviour of shales using available geological information and index properties. A statistical analysis has been performed; relationships among some index properties, geological data, and mechanical properties are presented. Such relationships may be of use for petroleum engineers in stability analysis during drilling and production, and for civil engineers in foundations, dams, and underground excavations, thus these models may aid preliminary estimates of properties and perhaps even reduce testing requirements.
