Log Analysis: Reading the Rocks Course Objectives: Basic questions in the petroleum geology require knowledge of the sub-surface rock and reservoir properties, and the spatial distribution of stratigraphic units and facies. The theory and practice behind a range of methods will be presented and through exercises that provide hands on experience to address real-world challenges of understanding the subsurface.
