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

Energy 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.

Wastewater Characterization: Chemical Oxygen Demand or Total Organic Carbon Content Measurement? [PDF]

Molecules
The long time (2 h) required for measurement, expensive chemicals (Ag2SO4), and toxic reagents (K2Cr2O7, HgSO4) limit the application of the standard method for measuring the oxygen equivalent of organic content in wastewater (chemical oxygen demand, COD)

High-resolution Quaternary record of marine organic carbon content in the hemipelagic sediments of the Japan Sea from bromine counts measured by XRF core scanner

Progress in Earth and Planetary Science, 2019
The marine organic carbon content in sediments is a useful tool for reconstructing past productivity in the ocean. Bromine has been proposed as a useful proxy for marine organic carbon, since bromine is more concentrated in marine organic matter compared
