... Abstract Gas hydrates are crystalline compounds that occur under appropriate pressure-temperature conditions when water forms a cage-like structure around a smaller guest molecule. The guest molecule can be methane, ethane, nitrogen, carbon dioxide etc. Gas hydrates are found in natural...

... Abstract The Vestnesa Ridge, a gas and gas-hydrate-charged sediment drift on oceanic crust in eastern Fram Strait, is the result of the tectonic rifting processes at the North American-Eurasian plate boundary and the initial water mass exchanges between the Nordic Seas and the Arctic Ocean...

... Abstract The Mackenzie Delta in Canada's Northwest Territories hosts manypermafrost-related gas hydrate accumulations that were indirectly discovered orinferred from conventional hydrocarbon exploration programs. In particular, gashydrate intervals characterized with high saturation show high...

These reservoirs are of the same type that may hostconventional hydrocarbon deposits in more deeply buried sediments...

... Abstract The results of short duration formation tests in northern Alaska and Canada have further documented the energy resource potential of gas hydrates and justified the need for long-term gas hydrate production testing. Additional data acquisition and long-term production testing could...

... production that can be used as the basis for monitoring hydrate dissociation, and the corresponding hydrate saturation and geomechanical status. Introduction Background. Gas hydrates (GH) are solid crystalline compounds of water and gaseous substances that are described by the general chemical formula G...

... traps before being converted to hydrate. These natural gas hydrate deposits have been identified in Russia, Canada, and Alaska using conventional hydrocarbon exploration techniques. In a very different permafrost hydrate paragenesis, diagenetic hydrate deposits have now been identified in veinworks...

... Abstract Geologic accumulations of natural gas hydrates hold vast organic carbon reserves, which have the potential of meeting global energy needs for decades. Estimates of vast amounts of global natural gas hydrate deposits make them an attractive unconventional energy resource. As with other...
