ABSTRACT:
The present invention relates to a method for determining at least one petroleum characteristic of a geologic sediment sample heated in a non-oxidizing atmosphere and an oxidizing atmosphere. The sample is heated to a first temperature value below 200.degree. C. for a predetermined period of time and then to a second temperature value ranging between 600 and 850.degree. C. according to a temperature gradient between 0.2.degree. C. and 50.degree. C./min. Carbon dioxide and carbon monoxide are continuously measured during the temperature stages in order to determine at least one petroleum characteristic, wherein said petroleum characteristic comprises a quantity of organic oxygen, inorganic oxygen, total organic carbon, or inorganic carbon.
