Gas Composition Analysis

Gas reservoir composition testing.

Intertek provides reservoir gas composition testing, including routine C1 to C6+ testing and extended gas analysis, and determination of inorganic gases like CO2 and N2. Clients are given critical analyses in the assessment of reservoir productivity for both wildcat and production well scenarios.

Gas composition analysis capabilities include stable carbon isotope analysis, allowing determination of the genetic origin of gas in the subsurface, continuity of reservoirs, and sourcing mechanisms for inorganic gases.

Professional sampling and analysis services for the determination of heavy metals in gas (Hg, As) are available, in addition to routine analysis for sulphur based elements such as H2S and Mercaptans. The elements hydrogen, carbon, nitrogen, oxygen and sulphur include two or more naturally occurring isotopes which do not undergo radioactive decay. These isotopic elements are key constituents of hydrocarbon reservoirs. The presence of stable isotopes are powerful tracers of geological processes, including fluids.

Gas composition testing and analysis:

  • Composition Analysis of Gases, C1, C2, C3, C4, C5, C6, C7, C8 and higher, including N2 and CO2
  • Calculation of Heating Value, Relative Density and Compressibility Factor. ASTM D1945-96, ASTM D3588-98
  • C1 to C5+ Headspace Gas analysis GC/FID
  • Stable Isotope Analysis of Gases Isotope using Mass Spectrometer
  • Real Time Measurement of Methane Isotopes
  • Natural Gas Testing  

Hydrocarbon gases detected and analyzed include Methane, Ethane, Propane, Butane, Pentane and higher. Gas sources include dissolved gas, associated gas, non-associated gas, natural gas liquids, sweet gas and sour gas. Non-hydrocarbon gases include Nitrogen and Carbon Dioxide.
