Oil Characterisation
Various (GC) analysis methods and preparation of oil fractions
Sample preparation
- Extracting (source)rock samples by Automated Solvent Extraction (ASE)
- Preparation of Saturates, Aromatics, Resin and Asphaltene fractions by SPE
- Topping of oil samples
- Perparation of n-alkane and branched/cyclyc fractions
SARA analysis
Analysis of Saturate, Aromatic, Resin and Asphaltene groups in crude oil samples or rock extracts by TLC-FID (Iatroscan)
Whole oil GC
- Integration of n-alkanes and most importand isoprenoids
- Calculation of maturity parameters like Carbon Preference Index (CPI) and Odd-to-Even-Predominance (OEP)
- Optional: integration of pseudo components
C7 GC
- GC-FID analysis of the light hydrocarbons in oil samples
- All peaks between C3 and toluene are integrated
- Internal standard is included
Next Step: Isotopic Analysis
Following compositional analysis, Isolab offers full stable isotope measurements including carbon and hydrogen, isotopes (bulk and compound-specific).
- (crude) oil samples
- rock extracts
- oil/extract fractions
