Rock Eval 7 analyser


The Rock-Eval 7 is the fully automated Vinci instrument that performs geochemical analysis of kerogen-containing rock samples. The powerful device, determines via high-temperature pyrolysis and subsequent oxidation, the critical kerogen and kinetics parameters which allow for example, the determination of Total Organic Carbon content (TOC), mineral carbon content (MINC), kerogen type, well log correlations and petroleum generation modelling. Specifically, the pyrolysis and oxidation products are measured by a Flame Ionization Detector (for hydrogen containing compounds) and an Infrared cell (for oxygen-containing products). Data from the Rock Eval can be input into the Vinci GEOWORKS software to compute rock characterization parameters, e.g. Hydrogen and Oxygen indices, shape factors etc.
