Organic geochemical techniques
　Biomarker analysis is an analytical technique used to identify unique organic signatures contained in crude oil and sedimentary rocks, and can be a powerful tool when incorporated into a hydrocarbon exploration workflow. JOGMEC uses this type of analysis to determine the source, age, thermal maturity, depositional environment, and degree of biodegradation of organic matter, as well as to characterize oil:oil and oil:source rock correlations. Additionally, gas chromatography-mass spectrometry (GC/MS) or GC/MS/MS is used to analyze lipid biomarkers. Recently, the developments in GC combustion isotope ratio mass spectrometry (GC/C/IR/MS), comprehensive two-dimensional GC (GCxGC), and liquid chromatography MS (LC/MS), have all facilitated the identification and quantification of biomarkers.
