Production response at a horizontal well produced through multiple fractures at a constant rate to highlight Flow Regimes 1 and 3; the fracture conductivity is assumed to be infinitely large, CFD ≥ 500. The unbroken lines are the pressure, pwD, and derivative, , responses respectively. Asymptotic solutions corresponding to short and long times, Flow Regime 1 and Flow Regime 3, respectively, are shown as dashed lines. The circles are solutions for a single fracture presented in the manner indicated in equation (58).
