This paper presentation shares the results of fingerprinting and biomarker analysis of 254 oil samples derived from 11 different fields and structures in Aryskum downfold of the South-Torgay depression for genetic classification of oils and prediction of petroleum migration pathways. According to the oil fingerprinting results based on patented Shell technology, 12 groups of oils were found.
Biomarker analysis was carried out for 20 oil samples, according to the results of which all studied oils were formed in terrigenous (shaly) OM, deposited in lacustrine environment. Based on the analysis, five prospective hydrocarbon accumulation zones were presented for increasing hydrocarbon reserves in the future. But the results of the performed studies provide valuable information only when integrated with confirmed geological and seismic data.
