Claim 16:
17. A method of evaluating a source rock, the method comprising:
performing pyrolysis on the source rock, wherein performing pyrolysis on the source rock comprises heating the source rock in an oven;
obtaining pyrolysis data for the source rock based on performing pyrolysis on the source rock;
determining a distillable hydrocarbon (S1) of kerogen in the source rock from the pyrolysis data;
determining a total organic carbon (TOC) content (in weight %) of the source rock from the pyrolysis data; and
determining a corrected milligrams of distillable hydrocarbon of the source rock per gram of the source rock (S1corr) using the equation

S1corr=S1o/(1−(% Loss n−C15+/100)),

wherein S1o is an original value of the milligrams of distillable hydrocarbon of the source rock per gram of the source rock and % Loss n−C15+ is a percent loss of a C15+ fraction of bitumen of the source rock.
