Organsko-geohemijska ispitivanja nafti južnog Banata

Crude oils from 5 oil fields in Southern Banat, Yugoslavia, were investigated using modern organic-geochemical techniques. GC and GC-MS (SIM) were applied for detecting the following components in crude oil samples : n-alkanes, isoprenoids (C 19 , C 20 ), steranes, diasteranes, tricyclic terpanes and pentacyclic triterpanes. The amounts and distributions of these classes of organic compounds were used to determine specific correlation parameters. Group correlation parameters were also determined
