+it against real-world Enhanced Geothermal Systems (EGS) empirical data from the Fervo Project Red site (Fervo Energy, 2026).
 For comparative context, it also includes the predictive temperature curve generated by Fervo's proprietary modeling.

 ## Methodology: Model Calibration and Parameterization
 
-The foundation of this validation lies in aligning the GEOPHIRES inputs with the physical realities of the Fervo Project Red site. To achieve this, the Gringarten analytical reservoir model was parameterized using published data and physical constraints derived from the site's initial reporting and recent updates.
