COURSE DESCRIPTION: The class provides an overview of how to maximize value in the upstream oil & gas exploitation space by leveraging subsurface excellence, innovation, and digitalization (SSXID). The subsurface is the foundation of an upstream oil and gas company. The rock and fluid characteristics are key to getting the best returns on your investment. A key financial metric is the cost/barrel. Subsurface excellence, innovation and digitalization are key to “increasing the denominator” of the financial metric.

The class stresses the importance of selecting the right development concept, then “doing the project right” and delivering the sanction promise (recoverable volume, production, cost and schedule). It highlights a systematic methodology for maximizing the ultimate recovery and “reducing the effective carbon footprint” for the development.

The class provides case studies of applying these principles of subsurface excellence, innovation, and digitalization to maximize exploitation value.
