For anybody inclined to be sympathetic to BP over the Gulf oil link, note that its latest capping effort is capturing about 10,000 barrels of oil a day, estimated to be about half of what is leaking.
But note that for months, BP claimed the total leak was only 5,000 barrels a day and roundly abused the very many experts who suggested otherwise – while rebutting any independent monitoring.
So what we now know is that total leakage is about four times what BP were claiming for 90% of the period covered by the disaster so far. Now, either BP don’t know much about oil wells, or they were deliberately lying about the extent of the disaster.
Oil is of course a perfectly natural substance which on occasion gets into the sea through seismic events, erosion or other natural cause. Chemical dispersants – most of which are varieties of detergent – are not natural substances at all. I am sceptical whether spraying the seas with chemical dispersants does not make the situation worse.
