Inverse modeling for estimating fluid-overpressure distributions and stress intensity factors from an arbitrary open-fracture geometry

► Analytical solution giving aperture geometry using the Fourier cosine series. ► Inversion model estimating the overpressure variation from the fracture geometry. ► The overpressure distribution increasing toward the tip of the mineral vein. ► The Fourier coefficients related to overpressure and critical stress intensity factor.
