Rock Eval Oil laboratory and field instruments

The Rock-Eval is a fully automated instrument that performs geochemical analysis of kerogen-containing rock.
The device determines, via high-temperature pyrolysis and subsequent oxidation, the critical kerogen and kinetics parameters.
It allows the determination of:

• Total Organic Carbon content (TOC)
• Mineral carbon content (MINC)
• Kerogen type
• Well log correlations
• Petroleum generation modelling

The pyrolysis and oxidation products are measured by:

• Flame Ionization Detector (FID) for hydrogen-containing compounds
• Infrared cell (IR) for oxygen-containing products
• Data from the Rock-Eval can be input into GEOWORKS software to compute rock characterization parameters such as:
• Hydrogen indices
• Oxygen indices
• Shape factors

• Pyrolysis oven temperature: 40 to 850°C
• Oxidation oven temperature: 200 to 850°C (optional: 1200°C)
• Oven temperature rates: adjustable from 0.1 up to 50°C/min, with 0.1°C step
• Material of crucible: Alumina (ceramic)
• Auto sampler capacity: 48 samples
• Detector: FID for hydrocarbons and IR for CO/CO2
• Gas carrier: Nitrogen (pyrolysis) and air (oxidation)
• Power supply: 110–220 VAC, 50 or 60 Hz
