A total of 5 Neogene, Paleogene of Cenozoic (No. 1–5) and 9 Cretaceous (No. 1–9) oils, as well as 6 Cretaceous calcareous core samples from wells A and B have been selected for this study. The oils investigated were selected from different formations and fields. Most of the Tertiary oils investigated are very heavy and severely biodegraded. The bitumens studied are also of Cretaceous age.

Total organic carbon content (TOC) and hydrocarbon generating potential of the carbonate samples were analyzed by Leco carbon analyzer and Rock-Eval pyrolysis, respectively. Solvent extraction was used to remove bitumen from the source rocks, while liquid chromatography (LC), FID- gas chromatography (FID-GC), and gas chromatograph-mass spectrometry (GC-MS) analyses were performed on both the oils and selected bitumen. Selected results from these analyses are discussed in the following chapter.
