Abstract Marginal fields, often characterized by limited reserves and low production rates, pose unique challenges in terms of return on investment (ROI) and long-term sustainability. Rising global energy demand and stringent environmental standards necessitate innovative and cost-effective approaches to field development. This paper introduces a holistic framework for designing Onshore Surface facilities that integrates combining lean engineering, modular design, digitalization, fiscal management, cost-effective execution, risk management, and economic efficiency. Drawing upon the successful case study of the Haliba Field by Al Dhafra Petroleum (ADNOC), the paper outlines practical pathways for transforming marginal fields into economically viable and environmentally sustainable energy assets. These strategies collectively aim to redefine marginal field economics through replicable, efficient, and environmentally conscious design models.
