Abstract:
1. A method allowing determination of at least one petroleum characteristic of a geologic sediment sample, wherein each of the two parts of the sample is heated according to an oxidizing heating comprising being heated in an oxidizing atmosphere, its temperature being successively raised to a first, then to a second value, said first value being below 200° C. then maintained substantially constant for a certain time, said second value ranging between 600° C. and 850° C. being reached with a temperature gradient ranging between 1 and 30° C./min, from said first value, characterized in that the amount of SO 2 contained in the effluent resulting from said oxidizing heating is measured continuously, every moment of the heating period of said sample, and in that the following stages are carried out: continuous measurement of the amount of SO continuous measurement of the amount of SO determining at least one petroleum characteristic of the sample by comparing the measurements of the amounts of SO
