Geochemical characteristics of Ordovician crude oils in the FI17 strike-slip fault zone of the Fuman oilfield, Tarim basin: Implications for ultra-deep hydrocarbon accumulation in the Tarim basin

Phase Behavior of the Mid-deep Carboniferous Near Critical Condensate Gas Reservoir in Junggar Basin, China

“…The discovery of the first near-critical condensate gas reservoir in the Junggar Basin, specifically within the mid-deep reservoir of the Carboniferous system at the Luliang uplift, marks a significant advancement in hydrocarbon exploration. , This reservoir, located at a well depth exceeding 5000 m, operates under a pressure (Pr) of 67.89 MPa and temperature (Tr) of 127.1 °C, which presents unique phase characteristics . Notably, (1) the SX well area exhibits favorable physical properties, dual medium characteristics, and a robust liquid supply capacity, contributing to stable production and pressure. , Additionally, (2) the identification of two distinct gas wells in the Junggar Basin, especially the well X, showcases exceptional performance metrics, including a notable “Two high and one low” well test performance, which diverges from typical reservoir behavior in the region . Moreover, (3) these recoveries highlight the reservoir’s remarkably low gas-to-oil ratio (GOR), distinguishing it from other gas reservoirs in the Junggar Basin …”
