UPC made a significant contribution to the first discovery of large condensate gas field in the Bohai Bay Basin

Recently, the China National Offshore Oil Corporation (CNOOC) announced that the BZ19-6 large condensate gas field was discovered in the Bohai Oilfield. This is the first large condensate gas field discovered in eastern sedimentary basins of China, and also the first large condensate gas field discovered in the lacustrine basin of China as well. Academician Prof. Fang Hao, Prof. Xingyao Yin, Prof. Zhiping Wu, Prof. Guanmin Wang, Prof. Zhenchun Li and other geoscientists of School of Geosciences (SG) have committed to oil and gas exploration in the Bohai Bay Basin in the past decades. They have been responsible for important research projects and made great contributions for the discovery of the BZ19-6 large condensate gas field.

The Bohai Bay Basin is a typical “oil-bearing basin” with the largest proved crude oil reserves and the largest oil production capacity in China. In order to solve this world-class problem in finding large gas fields in this basin, the CNOOC exploration team cooperated with China University of Petroleum (East China), China University of Geosciences (Wuhan), China University of Petroleum (Beijing), and Chengdu University of Technology to investigate the mechanism of gas generation, the occurrence of high-quality reservoir, and the enrichment model of petroleum, according to the 'production-study-research' mode in scientific research and cooperation. The theory of 'gas generation derived from lacustrine organic matter' was proposed for the first time, and successfully contributed to the discovery of the BZ19-6 large condensate gas field. The discovery of this gas field is a major breakthrough in concept of “gas exploration in the oil-bearing basin” and will significantly enhance the stable supply of gas and provide green, clean and safe energy security for the Beijing-Tianjin-Hebei region, with enormous economic benefits.

It is reported that the BZ19-6 project has already handed over to the country with proved gas reserves of 1.186×108 m3and condensate oil reserves of 1.14×108t, with a total of proved reserves, probable reserves and possible reserves of 8×108t of oil equivalent.
