The fraction of two fracture system exhibiting thermal performance enhancement as a function of \(\sigma _h/\left\langle w \right\rangle\). The Hurst coefficient \(\zeta\) is equal to 0.8 and the wellbore spacing L/(2R) is equal to 0.4. The curves give theoretical predictions based on a Gaussian distribution of \(\Theta _p\). The squares are the fraction of reservoirs that outperform a base case with an equal flow split, F. The diamonds are the fraction of reservoirs that outperform a base case with a constant aperture within each fracture but the same flow split as observed in the simulations, \(F^{*}\). The one fracture results and the theoretical fit was also plotted
