Double bottom simulating reflectors and tentative interpretation with implications for the dynamic accumulation of gas hydrates in the northern slope of the Qiongdongnan Basin, South China Sea

Wei Zhang et al.

Summary: Based on seismic data, this paper identifies double bottom simulating reflectors (BSRs) in the northern slope of the Qiongdongnan Basin (QDNB) in the northern South China Sea and explores their relationship with gas hydrate systems. The presence of double BSRs suggests the dynamic accumulation of gas hydrates and free gas, which is significant for the exploration of gas hydrate resources in submarine settings.

Spatial-Temporal Evolution of the Gas Hydrate Stability Zone and Accumulation Patterns of Double BSRs Formation in the Shenhu Area

Yingrui Song et al.

Summary: This study examines the thickness and evolution of the methane gas hydrate stability zone (GHSZ) in the Shenhu area. The results show that the thickness of the GHSZ varies over time with an overall thickening trend. Two mechanisms for the double bottom-simulating reflectors (BSRs) in the Shenhu area are identified, and the relationship between the evolving GHSZ thickness and the dynamic accumulation of natural gas hydrates (NGHs) is clarified. This study provides valuable insights into the formation of multiple BSRs and the migration, accumulation, and dissipation of NGHs during the dynamic accumulation process.

Geochemical insights into contribution of petroleum hydrocarbons to the formation of hydrates in the Taixinan Basin, the South China Sea

Yan Li et al.

Summary: The study reveals the presence of branched saturated fatty acids from sulfate-reducing bacteria in methane hydrate-bearing sediments in the South China Sea, indicating active microbial activities and significant environmental changes. Carbon isotope analysis suggests that alkanes and methane in hydrate deposits may originate from deep oil/gas reservoirs rather than methane, providing evidence of the contribution of deep oil/gas reservoirs to the formation of methane hydrate deposits in the South China Sea.
