  • Temperature profile for rock sample composition analysis
    Patent number: 10488327
    Abstract: A method for analyzing the petroleum content of a rock sample includes at least three repetitions of heating a rock sample to a holding temperature, holding the rock sample at the holding temperature for a holding period, and collecting data about the rock sample during each holding period. The holding temperature for each subsequent holding period may be greater than or equal to a previous holding temperature. The data collected may be analyzed to determine the S1 parameter and calculated to determine the API gravity of the rock sample.
    Type: Grant
