I have good news, someone has called and involved Norwegian scientists. So a couple of weeks to late, you have the sense to ask those with experience and access to the latest technology to recover and plug the well.
Having said this, I also make you aware that an offhore rig also sank last week (Thursday) off the coast of Venezuela. The Blow-Out Preventor ("BOP") worked fine here, as did the evacuation of the platform. Venezuela started offshore without pride and with the intent to protect the marine life in the Carribean. They wanted the same regulations as Norway imposed, received them and translated them to Spanish. The US oil companies called them "Socialistic Regulations" and used them in silly jokes.
If caring for others is "socialism" where does that leave the environmental issues?
