Geochemistry can be applied to all phases of a field life cycle: exploration, appraisal, development, production, and abandonment. Malcom interactive fluid characterization software offers geochemical engineering solutions by processing gas chromatography data (GC-FID, GC-MS, GC-MS-MS, GC-2D, etc.) from different vendors. The comparison of oil GC fingerprints provides information on biomarkers, reservoir connectivity, estimation of the size of reservoirs, and production allocation calculation. With Malcom software, a comprehensive suite of tools are embedded within a single application to process chromatography data and to perform statistical calculation, delivering fast data interpretation.
