A: Best fit aperture distribution calibrated by frictional pressure loss and an inert tracer test. Black triangles represent the location of the injection and production wells. B: Measured and simulated residence time distribution (RTD) curves for inert tracers throughout 6 days of fluid circulation. Note that lighter gray lines represent multiple repetitions of the machine learning algorithm, while the black line represents the repetition that provided the best agreement with field observations. Highlighted model fit in Panel B used the best-fit aperture distribution in Panel A as input.
