Maximizing production from brownfields and extending the plateau have become utmost priorities for exploration-and-production companies the world over. This calls for a synergistic approach involving close coordination of various disciplines—subsurface, surface, well drilling and completions, and facilities engineering—to achieve the common goal of maximizing production and recovery. There is a growing awareness that maximizing field production involves not only having a clear understanding of subsurface intricacies but also ensuring that existing surface facilities are performing at their best to handle production in an environmentally safe manner. Many papers presented during the past year at SPE conferences and surveyed for this review address these issues. Infill drilling and optimization of ongoing waterflood are two activities planned for revitalization of mature fields.
