This session examines innovative operating business models and contractual frameworks designed to maximise economic value, improve project viability, and optimise investment in oil and gas developments. Key topics include the application of the gross split model to monetise marginal and very small oil discoveries, particularly those producing approximately 50–100 barrels per day. The session will also explore integrated drilling services as an approach to improving operational efficiency, reducing costs, and enhancing service delivery. In addition, it will address Lump Sum Turnkey (LSTK) contracting models, focusing on their financial, commercial, and contractual structures, risk allocation, cost control, and project execution considerations to support sustainable and cost-effective field development.
