A rock sample is subjected to a heating sequence in an inert atmosphere, the effluents resulting from this heating are oxidized, the hydrocarbon-based compounds, the CO, the COand the SOreleased are measured, and a pyrolysis pyritic sulfur content is deduced therefrom. The residue resulting from the heating in an inert atmosphere is then heated in an oxidizing atmosphere and the CO and the COreleased are measured. The pyritic sulfur content is determined at least from the pyrolysis pyritic sulfur content and from a parameter which is a function of the hydrogen content and of the oxygen content of the organic matter of the sample. It is also possible to determine the organic sulfur content from the pyritic sulfur content and from a measurement of the SOduring the heating sequence in an oxidizing atmosphere.

Process for quantifying the pyritic sulfur and the organic sulfur of a rock sample

A method which distinctly characterizes and quantifies the pyritic sulfur and the organic sulfur of a sedimentary rock sample. A rock sample is subjected to a heating sequence in an inert atmosphere which produces effluents resulting which are continuously oxidized. SOis continuously measured, and a pyrolysis sulfur content and a pyrolysis pyritic sulfur content are deduced therefrom. The residue from heating in an inert atmosphere is then heated in an oxidizing atmosphere. Released SOis continuously measured and at least an oxidation sulfur content is deduced therefrom. The pyritic sulfur content is determined from pyrolysis, a weighting function, a second parameter representing the impact of the mineral matrix and a third parameter representing the impact of the organic matrix.

Method for quantifying the pyritic sulfur and the organic sulfur of a rock sample

The invention is a method of assessing at least one petroleum characteristic of a rock sample. Starting from a temperature ranging between 50&#xb0; C. and 120&#xb0; C., the temperature of a rock sample is raised to a temperature ranging between 180&#xb0; C. and 220&#xb0; C. Temperature (T) is maintained for a predetermined time duration. The temperature of the sample is increased to a temperature (T) ranging 330&#xb0; C. and 370&#xb0; C. Temperature (T) is maintained for a predetermined time duration. The temperature of the sample is then raised to a temperature (T) ranging 630&#xb0; C. and 670&#xb0; C. Three quantities S, Sand S, representative of the amount of hydrocarbon compounds released during the temperature change stages, are measured and at least one petroleum characteristic of the sample is deduced from these quantities.

Method for determining quantities of hydrocarbon compounds contained in rock from a geological sample

The present invention relates to a method of estimating, for a petroleum feedstock, values representative of the sulfur and carbon distributions in atmospheric and vacuum distillation residues, and a value representative of the sulfur content in coke. According to the method, the following stages are carried out:

Method for fast estimation of distillation residues and coke characteristics

The invention relates to a method and to a device for sulfur characterization and quantification in a sample of sedimentary rocks or of petroleum products wherein the following stages are carried out: heating said sample in a pyrolysis oven () in a non-oxidizing atmosphere, oxidizing part of the pyrolysis effluents and continuously measuring the amount of SOgenerated by said part after oxidation, then transferring the pyrolysis residue of said sample into an oxidation oven (') and continuously measuring the amount of SOcontained in the effluents resulting from said oxidation heating.
