2026-07-21 CarbGeo-3D: A Synthetic Three-dimensional Lithology-Resistivity Dataset of Carbonate Geothermal Reservoir doi:10.57760/sciencedb.40807 en We introduce CarbGeo-3D, a comprehensive synthetic dataset comprising 5,000 paired 3D lithological models and continuous resistivity volumes. To our knowledge, CarbGeo-3D represents one of the first openly available large-scale datasets that jointly provide paired three-dimensional lithofacies and resistivity models for carbonate geothermal reservoirs while explicitly incorporating geological process knowledge into the generation workflow. CarbGeo-3D is designed to support the development, benchmarking, and reproducible evaluation of data-driven subsurface characterization methods by providing a large collection of geologically plausible carbonate geothermal reservoir models. The synthesized lithology and resistivity models of carbonate geothermal reservoirs are fully aligned in spatial grid size (default 128 × 128 × 128), allowing them to be directly used as paired geological-geophysical data for machine learning, geophysical inversion, uncertainty quantification, and surrogate modeling applications. The dataset is released in several standardized formats. The dataset includes *.npy to be compatible with mainstream deep learning frameworks, *.vtk to support professional geophysical visualization software such as ParaView, and *.gslib to be compatible with geostatistical software packages. The parameters of generating lithology-resistivity data pairs can be flexibly adjusted by the user according to the specific geological and geophysical characteristics of the study area.
