Abstract: A method for analyzing total oil in place and fraction that is movable oil in a fine gain rock formation includes monitoring thermal extraction of hydrocarbon and non-hydrocarbon compounds from a sample of a subsurface formation by heating the sample. The heating has a selected initial temperature, and a temperature increase at a selected rate to a final temperature. The extracted hydrocarbon and non-hydrocarbon compounds are passed through a capillary column to a flame ionization detector. Types of hydrocarbon and non-hydrocarbon compounds and relative fractional amounts of each type thereof are determined from the sample by analyzing a chemical thermogram generated by the flame ionization detector.
