Libya have been investigated by a variety of organic geochemical methods, including Rock-Eval pyrolysis (RE), gas chromatography (GC), gas chromatography mass spectrometry (GCMS), and graptolite reflectance. Rock samples were collected from the Tanezzuft Formation (`cool' shales) from several wells of A-Field located in Block NC-115. Furthermore, crude oil samples were collected from A-, R-, and I-Fields in NC-115 and NC-186 Blocks. The distributions of n-alkanes, isoprenoids, terpanes, and steranes (saturate fractions) along with phenanthrenes, mono- and triaromatic steroid hydrocarbons (aromatic fractions) were studied and used to determine organic matter composition, nature of depositional environments and levels of thermal maturity for both rock and crude oil samples.The results from the study of the rock samples show a close correlation between RE data and the biomarker parameters. Based on RE data, org...
