The Dabei gas field is a natural gas field located in the Kuqa Subbasin in Xinjiang, China. Discovered in 2006, it was developed by the China National Petroleum Corporation, determining it to have initial total proven reserves of around 5.25 trillion ft3 (150 km3). It began production of natural gas and condensates in 2007, with a production rate of around 479.5 million ft3/day (13.7×105 m3).[1] It is the deepest and most complex continental condensate gas field in China.[2]
Overpressure evolution of the reservoir indicates that an intense tectonic compression began at circa 5 Ma, which caused thrust activation and concomitant oil charge into the relatively porous part of the reservoir. Subsequent tectonic compression caused uplift and erosion associated with thrusting at the end of the Kuqa Formation deposition (ca. 3 Ma), with thrust faults and fractures acting as major migration pathways for the gas accumulation in the already-tight sandstone reservoir resulting from both compaction and tectonic compression.[3]
