Total organic carbon content logging prediction based on machine learning: A brief review

open access: yesEnergy Geoscience, 2023
The total organic carbon content usually determines the hydrocarbon generation potential of a formation. A higher total organic carbon content often corresponds to a greater possibility of generating large amounts of oil or gas.
