Our laboratory






Total E&P ASD has its own laboratory for measuring the porosity and density of rock samples. 

The latter allows the connection of standards to the International System of Units (SI).








The activities accredited with the ISO 17025 standard in our laboratory: 




The procedure is available by following this link: "Determination of the density and open porosity of natural rock" (document in French)

Laboratory actions:

  • Evaluate the porosity and density of rock samples from the center standards (samples are stored under the same conditions as the standards.)
  • Ensure the metrological traceability of Total E & P ASD standards to the International System of Units (SI)
  • Control the quality of the water in which the standards are immersed by means of analysis (without ISO 17025 accreditation): fluid density, pH, conductivity, turbidity, dissolved oxygen, chloride ion and calcium measurement (see photo below).
