GEOLOG has just presented at the International Petroleum Technology Conference (IPTC) in Bangkok - Thailand, “Deep-Spectrum Gas Chromatography & Carbon Isotopes Analysis While Drilling Enhance Value of Real-Time Formation Evaluation, Reducing Interpretation Uncertainty”. This paper highlights improvements in surface logging technology allowing real-time quantitative analyses. It references case studies describing direct comparisons with PVT data, identifying hydrocarbons of different sources and maturities to evaluate migration pathways and source provenance.
