We estimate effective fracture porosity and fracture density using permeability, aperture, and a roughness factor. The dataset is designed to support analyses of the relationship between hydraulic and petrophysical properties and depth, as well as the statistical distribution of these properties in low-permeability crystalline environments. Particular emphasis is placed on the strong variability and skewness of porosity and permeability values observed across datasets.-123.54169.67-45.4968.02Androscoggin, Maine, U.S.A., North America
