I don't have the answer to this but I've been wondering could a rig have been set up in much shallower waters and then used slant drilling techniques to access this oil? Had a wellhead failure occurred there (shallow waters), at least divers might access directly instead of via remote robotics. I do believe oil is a
replenishing material but the rate of withdrawal to replenish of reserves seems at present to factor in. Finding alternatives for not only the oil itself but also alternatives that are local to use, renewable eg sustainable, and don't require our worrying with access to foreign sources is just a win/win IMO.
All the Cheech and Chong jokes aside, I still think
hemp oil could prove of some if not a lot of value if for nothing more than to replace petro needs in non-transport products like say plastics for example. Aside from the sorry excuse of the
moral purity crowd back in the 30's, the bigger driving force behind the illegalization of all cannabis plants (
marijuana and
industrial hemp) was likely more from the efforts of the
wood paper interests and of course the alcohol industry who had just gotten the
green light to crank all the breweries back up. Last thing they needed was a competing product that one could grow in ones backyard but then again maybe the big holdup now to letting people grow their own is the fear of a homegrown, local
competitor to the oil marketplace?
One might be well served to ask in whose interest the gov't (both parties) is serving? But take heart, remember, we have a "free market" so all is well!
