Comparing Reinjection Strategies in Naturally Fractured Geothermal Reservoirs: A 3D Numerical Modeling Approach

The strategic placement of reinjection wells within geothermal reservoirs is a pivotal determinant of sustainable and maximized thermal recovery. Minimizing temperature decline and maintaining effective pressure support over extended timescales are crucial objectives. This investigation comprehensively evaluates the implementation of diverse well injection patterns, including infield injection, dipole injection, and peripheral injection well configurations, within a heterogeneous geothermal reservoir characterized by the presence of faults in western Turkiye. The influence of these geological features and their associated properties on both field-scale performance and individual well productivity is rigorously assessed through a three-dimensional numerical reservoir simulation. By optimizing well configurations for various production-injection strategies, this study provides valuable insights into enhancing geothermal reservoir development in western Turkiye, ultimately maximizing thermal recovery for sustainable energy production.
