JPT Mature Fields and Well Revitalization

SPE.org 

Maximizing production from brownfields and extending the plateau have become utmost priorities for exploration-and-production companies the world over. 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. Drilling through differentially depleted, multilayered reservoirs and the untapped deeper zones is a challenging task. Robust knowledge of rock properties, formation pressures, magnitude of in-situ stresses, and their evolution with production and depletion is essential for successful drilling of new wells in the redevelopment of mature fields.
