hydrate layer and underlain by an aquifer of unknown strength. The field was put on production in 1970 and has produced
intermittently since then. Some characteristic observations were increase in average reservoir pressure during shut-in, perforation
blocking due hydrate formation and no change in gas-water contact. It is believed the increase in reservoir pressure was caused by
the hydrate layer dissociation, rather than aquifer influx.
And the hydrates described in the opening article in this thread are also not the same thing as hydrate mining. Or did you not read the article?
Collett said the newly found deposits are more promising commercially because they are sizable and located in porous, permeable sands like those from which conventional oil and gas are extracted.
They also are less risky environmentally than shallower hydrate formations because they are trapped under impervious shales more than 2,000 feet under the seabed, Boswell said.
These are more like those ones in Alaska's North Slope.
