Hydrate Formation News Today

When the new, more tightly fitting cap placed on the wellhead, a fraction of the amount of oil that escaped to the gulf of mexico for three months escaped in the water. another sign of seepage has been ruled to be not related but there are still great concerns. >> the leakage is occurring located right about here. there is hydrate formation on the side of the capping stack as we move forward. >> admiral allen showing everyone on top of thecaing stack the new leak of oil has been detected. spotte...

>> greta: where the hydration is isnt that ineffective because it blocks it? is that why thats been ineffective why is that effective in containing the leak? >> the issue is the quantity ofs go and seawater in the large dome. that is a difficult combination. so, by moving to a smaller dome well have less seawater and hopefully, a better chance of minimizing the hydrate formation and being able to get in sort of system to work. >> greta: are you getting everything you need? i realize bp is scramb...

Dome. yesterday evening we lowered that to the sea floor and began to place it over the source of the leak. i think as we expressed numerous times, this particular operation has never been done before at this depth. we shared that the big technical challenge was with hydrate formation. that is when gas combines with water under certain pressure and temperatures that form as crystal similar to ice. what happened as we were placing the dome over the leak source a large volume formed inside the top...

Lowered the dome. the dome had to be lowered carefully over the sea bed. we were successful in placing it over the top of the leak site. these gas hydrates are actually like crystals, like ice crystals. of course they are lighter than water. what they did is form on the inside of the dome which tried to make the dome buoyant. it also plugged up the top of the dome where the oil would come out of. what we had to do was pick the dome back up, set it over to the side while we evaluate what options ...
