The document provides an overview of the key technical disciplines involved across the different stages of the oil and gas industry life cycle, from exploration through to decommissioning. It discusses the roles of professionals such as geologists, geophysicists, reservoir engineers, drilling engineers, production engineers, and health and safety specialists. The exploration stage involves predicting oil and gas reserves, while development includes well drilling, infrastructure installation, and production planning. Decommissioning encompasses cleaning up facilities and safely removing offshore structures. Subsea engineering roles have also emerged to support offshore oil and gas extraction.
