This Study focused on identification and quantification of Atmospheric and vacuum oil residue using GCMS technique. A total of ten Oil residues samples were used in this study, five each from atmospheric and vacuum distillation. The samples were obtained from Kaduna Refining and Petrochemical Company (KRPC),a subsidiary of Nigeria National Petroleum Corporation (NNPC).The samples were prepared and analysed using GC-MS. The results inferred that the crude oils studied have similar hydrocarbon group type’s i.e paraffinic, olefinic and Aromatic group types but differ in individual hydrocarbon. Atmospheric oil residue has higher amounts of Paraffins and Aromatics than Vacuum residue and lower amounts of Oxygenates and Olefins compare to Vacuum residue.
