Widespread natural methane and oil leakage from sub-marine Arctic reservoirs
Nature Communications, 2023 Barents Sea shelf experienced >30 episodes of glaciation which scraped off layers of rocks and led to petroleum reservoirs exposed onto the seafloor. Today, such uncapped reservoirs produce strong fluxes of methane gas and oil into the ocean.

Evaluation of alternative horizontal well designs for gas production from hydrate deposits in the Shenhu area, South China Sea [PDF]
, 2010 Gas hydrate deposits were confirmed in the Shenhu Area, the north slope of South China Sea during a drilling expedition in 2007. Hydrate deposits in the area are distributed in disseminated forms in forams-rich clay sediments with permeable overburden ...
