 Fracture Height, 95, -- Actual fracture geometry is irregular and heterogeneous; this height complies with the minimum height required by the implemented bench design (200 ft; 60.96 meters) and yields an effective fracture surface area consistent with simulation results in Singh. et al., 2025.

Note that this value affects heat to power conversion efficiency. The effects of hourly and seasonal ambient temperature fluctuations on efficiency and power generation are not modeled in this version of the case study.
