This dataset supports the doctoral research entitled “Model Uncertainty Quantification to Improve Oil Reservoir Simulations”. It includes numerical reservoir simulation outputs, proxy model predictions, dimensionality-reduced geological representations, reconstructed 3D geological properties, and uncertainty quantification results obtained using deep learning models. The data were generated from a Brazilian offshore oil field and are intended to support reproducibility, validation, and future research on proxy modeling, geological uncertainty reconstruction, and uncertainty quantification in reservoir engineering.
