Laboratory of Petroleum Geochemistry


Purposes of the natural gas geochemical analysis

  • Genetic type of: natural gas, shale gas, coal-bed methane gas, tight gas, greenhouse gases, etc.
  • Proportion of mixing between microbial and thermogenic gases
  • Maturity of source organic matter
  • Biodegradation influence
  • Migration distance

Geochemical analysis – conventional natural gas, unconventional gases (shale, tight)

  • Gas sampling and preparation
  • Molecular composition: CH4, C2H6, C3H8, iC4, nC4, iC5, nC5, neo-C5, C6, N2, O2, Ar, He, CO2, H2, H2S
