  • Method for determining oil-related characteristics of geological sediments from small samples thereof
    Patent number: 4229181
    Abstract: Sample of geological sediment is heated preferably to a first temperature in the range from 50.degree. C. to 65.degree. C., then to a second temperature in the range from 200.degree. C. to 350.degree. C. and finally to a third temperature in the range from 550.degree. C. to 600.degree. C. Oil-related characteristics of the sediments are derived from the respective amounts of hydrocarbons released by the sample during these three steps.
    Type: Grant
    Filed: September 8, 1978
    Date of Patent: October 21, 1980
    Assignee: Institut Francais du Petrole
    Inventors: Jean Espitalie, Jean-Loup Laporte, Marcel Madec, Francois Marquis
  • Method and device for analyzing geological sediments and for determining their organic sulfur content
    Patent number: 4213763
    Abstract: A sample of the studied sediments is heated in a non-oxidizing atomosphere.The organic material of the sediment is then pyrolyzed and the released products are oxidized. The sulfur content of the sulfur compounds produced by this oxidation is continuously measured in relation with the temperature in the form of an electric signal. The overall sulfur content of the sample is utilized in combination with a parameter characterizing the sample to determine the degree of evolution of the organic material in the sediment.

  • Method for determining oil-related characteristics of geological sediments from small samples thereof
    Patent number: 4153415
    Abstract: The method comprises heating a sample successively to a first temperature comprised in the range from between 200.degree. to 400.degree. C., then to a second temperature preferably from 550.degree. C. to 600.degree. C., measuring the amount of native hydrocarbons vaporized at the first temperature and the amount of hydrocarbon compounds produced by pyrolysis of the organic material of the sample at the second temperature.Characteristics of the sediments are derived from the two measured values.
