Abstract
A system is provided for detecting the mass of oil in an inorganic mineral of shale. The system operates by performing an extraction test on a first shale sample by using chloroform to obtain a total content of shale oil in the shale; enriching kerogen from the second shale sample to obtain dry kerogen; and performing an extraction test on oven-dried kerogen by using chloroform to determine the mass of extracted kerogen. The system also operates by determining the mass of the oil in the organic matter of the shale sample and the mass of the oil in an inorganic mineral of the shale; establishing a model for predicting a ratio of the mass of the oil in the inorganic mineral of the shale to the mass of the oil in the organic matter; and using the prediction model to determine the mass of oil in an inorganic mineral.
