  • Patent number: 10895567
    Abstract: 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. SO2 is 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 SO2 is 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.

  • Patent number: 10794155
    Abstract: The invention is a method for exploiting a subterranean formation including hydrocarbons with at least one lithologic facies of the formation having undergone at least one diagenetic phase over geological times. From at least one sample of rock obtained from the formation, from measured production data relating to the formation and from a meshed representation representative of the formation, each mesh of the meshed representation is determined including at least one indicator relating to the distribution of the facies present in the mesh. The method comprises a step of history matching in which at least one of the adjustment parameters is the diagenetic state of the identified facies.

  • Publication number: 20190079065
    Abstract: Method for distinctly characterizing and quantifying 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, the effluents resulting from this heating in an inert atmosphere are continuously oxidized, the SO2 released is 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, the SO2 released is continuously measured and at least an oxidation sulfur content is deduced therefrom. The pyritic sulfur content is determined from the pyrolysis pyritic sulfur content and from a weighting function taking account of a first parameter representing a pyrite thermal degradation rate, a second parameter representing the impact of the mineral matrix and a third parameter representing the impact of the organic matrix.
