Abstract

The seabed of the South China Sea (SCS) is a vast reserve of oceanic gas hydrates, a potential future energy attracting global interest. Gas production from oceanic hydrates poses a significant concern of impending disasters of massive seabed instability. Data inventory of hydrate reservoirs becomes essential to optimize hydrate production strategies and to minimize potential risks. To facilitate the data mining for future risk assessment of gas production in SCS, this study compiles a GIS-driven database for managing and analyzing information of gas hydrate reservoirs in SCS. The information, collected by different agents with various techniques at various scales and accuracies, is overlaid and geo-referenced. The possible bounds of hydrate reservoir are roughly deduced at the regional scale from the data of water depth and the phase equilibrium equation of hydrate. The presented GIS-driven database is adaptable for data accumulating over time. This study is a preliminary and significant step towards a regional risk analysis of hydrate production in SCS.
