Characterization of Natural Gas Hydrate Constrained by Well and Seismic Data in Qiongdongnan Basin
EnergiesThis study investigates the natural gas hydrates within the Qiongdongnan Basin by integrating well-log and seismic data. Through pre-stack inversion and rock physics analysis, key parameters such as P-wave and S-wave impedances were utilized to ...

Geophysical Research Letters, Volume 50, Issue 24, 28 December 2023., 2023 Most marine gas hydrate systems follow a vertical pattern with hydrate overlying free gas. Here we document the discovery of a gas to hydrate system in a horizontal sand layer in the Qiongdongnan Basin of the South China Sea.

Geochemical characteristics and origins of natural gases in Yinggehai and Qiongdongnan Basins of South China Sea [PDF]
Scientific ReportsDF13-2 and YC13-1 are two large gas fields found in Yinggehai and Qiongdongnan Basins, respectively, and the gas-source correlation is a very challenging scientific exercise due to the similarity of their hydrocarbon isotoperatios and gas dryness.

Late Miocene Red River submarine fan, northwestern South China Sea [PDF]
Journal of Earth Science, 2011 Based on high-resolution 3D seismic data, we document the polygonal faults within the Miocene Meishan (sic) Formation and Huangliu (sic) Formation of the Qiongdongnan (sic) basin, northern South China Sea. Within the seismic section and time coherent slice, densely distributed extensional faults with small throw and polygonal shape were identified in ...
