Geology of Greenland Survey Bulletin, 180, 100-110. https://doi.org/10.34194/ggub.v180.5093 _______________ The Danish Lithosphere Centre (DLC) was established in 1994 and one of its principal objectives in the first five-year funding cycle is the study of Precambrian orogenic processes. This work initially focused on the thermal and tectonic evolution of the Nagssugtoqidian orogen of West Greenland. During the first two field seasons (1994 and 1995) most efforts were concentrated in the southern and central portions of the orogen. The 1997 field season was the third and final in the project in the Nagssugtoqidian orogen and emphasis was placed on the central and northern parts of the orogen in order to complete the lithostructural study of the inner Nordre Strømfjord area and to investigate the northern margin of the orogen (NNO in Fig. 1). This report is partly a review of selected research results obtained since publication of the last Review of Greenland activities (van Gool et al. 1996), and also partly a summary of field activities in Greenland during the summer of 1997.

The condensate gas reservoirs of the Jurassic Ahe Formation in the Dibei area of the Tarim Basin, northwest China are typical tight sandstone gas reservoirs and contain abundant resources. However, the hydrocarbon sources and reservoir accumulation mechanism remain debated. Here the distribution and geochemistry of fluids in the Ahe gas reservoirs are used to investigate the formation of the hydrocarbon reservoirs, including the history of hydrocarbon generation, trap development, and reservoir evolution. Carbon isotopic analyses show that the oil and natural gas of the Ahe Formation originated from different sources. The natural gas was derived from Jurassic coal measure source rocks, whereas the oil has mixed sources of Lower Triassic lacustrine source rocks and minor amounts of coal-derived oil from Jurassic coal measure source rocks. The geochemistry of light hydrocarbon components and n-alkanes shows that the early accumulated oil was later altered by infilling gas due to gas washing. Consequently, n-alkanes in the oil are scarce, whereas naphthenic and aromatic hydrocarbons with the same carbon numbers are relatively abundant. The fluids in the Ahe Formation gas reservoirs have an unusual distribution, where oil is distributed above gas and water is locally produced from the middle of some gas reservoirs. The geochemical characteristics of the fluids show that this anomalous distribution was closely related to the dynamic accumulation of oil and gas. The period of reservoir densification occurred between the two stages of oil and gas accumulation, which led to the early accumulated oil and part of the residual formation water being trapped in the tight reservoir. After later gas filling into the reservoir, the fluids could not undergo gravity differentiation, which accounts for the anomalous distribution of fluids in the Ahe Formation.
