Sentences with phrase «gas hydrate stability»

Improvements in our understanding of clathrate chemistry and sedimentology have revealed that hydrates form in only a narrow range of depths (continental shelves), at only some locations in the range of depths where they could occur (10 - 30 % of the Gas hydrate stability zone), and typically are found at low concentrations (0.9 — 1.5 % by volume) at sites where they do occur.

Ohio State University will conduct research in collaboration with the Bureau of Ocean Energy Management to increase our understanding of the occurrence, volume and distribution of natural gas hydrates in the northern Gulf of Mexico using more than 1,700 petroleum industry well logs that penetrate the gas hydrate stability zone, or the offshore depths and locations where gas hydrates flourish.
