TL;DR: In this paper, a total of 108 drill stem test (DST) crude oil samples and 10 reservoir fluid inclusion samples were investigated geochemically to identify the characteristics and origin of the crude oil in the Tazhong Uplift, Tarim Basin, NW China.

TL;DR: In this article, the authors analyzed three major hydrocarbon bearing intervals in the Lunnan lower bulge for their stable carbon isotopes and molecular biomarkers and concluded that the recently discovered deep (6500m) eastern Lungu giant Ordovician gas condensate pool with an estimated reserve of 723 million bbl oil equivalent is a secondary hydrocarbon accumulation derived from the mixing of an early formed oil and a late formed gas.

TL;DR: In this article, an integrated geochemical approach was utilized to unravel the characteristics, origin and alteration of the deep oils in the Tazhong Uplift, Tarim Basin whereas the oil source is still controversial.

TL;DR: In this paper, deeply buried heavy oils from the Tabei Uplift of the Tarim Basin have been investigated for their source origin, charge and accumulation time, biodegradation, mixing and thermal cracking using biomarkers, carbon isotopic compositions of individual alkanes, fluid inclusion homogenization temperatures and authigenic illite K-Ar radiometric ages.

TL;DR: In the Tabei Uplift of the Tarim Basin, there were three main periods of hydrocarbon accumulation in the late Caledonian stage, the late Hercynian stage and the late Himalayan stage as mentioned in this paper.
