Gas Hydrate Drill Rig at the Mallik Test Site in Canada
A drill rig at the Mallik test site in Canada's Mckenzie Delta. USGS joined the Geological Survey of Canada, JAPEX, and the Japanese National Oil Company to drill test wells for natural gas production from gas hydrate deposits.

Gas Hydrates in Marine Sediments off the Oregon Coast
During Ocean Drilling Program Leg 204, nine sites were cored and wireline logged on the Oregon continental margin to determine the distribution and concentration of gas hydrates in an accretionary ridge setting, investigate the mechanisms that transport methane and other gases into the gas hydrate stability zone, and obtain constraints on physical properties of

Atigun River in Alaska Brooks Range foothills
View westward along Atigun River in Atigun Gorge. Rocks in foreground are Lower Cretaceous Fortress Mountain Formation. Rocks in gorge, along river, are Lower Cretaceous Okpikruak Formation. Mountains on horizon are mostly carbonates of Carboniferous Lisburne Group. Location in Brooks Range foothills, about 100 miles southeast of Umiat.
