Strategic Management of Mature and Marginal Fields in Brazil explores how these often underestimated assets can be revitalized through an integrated and efficient management model. The book revisits the historical and regulatory evolution of the sector, analyzes the main technical, economic, and environmental challenges of onshore production, and presents a detailed case study that demonstrates the practical impact of cost reduction, operational efficiency, and governance.

By proposing a holistic model grounded in six essential pillars, the author shows that mature fields can play a strategic role in energy security, wealth creation, and regional development. The work serves as a key reference for those seeking to understand the present and future of onshore production in Brazil.
