BP Permanently Seals Gulf Oil Well
rexjoec writes "BP has finally plugged the Macondo well. This announcement came yesterday after $9.5 billion (through September 17) in expenditures and five months of continuous effort."
From the LA Times: "Of the estimated 4.9 million barrels of oil that gushed from the well, 25% was burned, skimmed or piped to tanker ships. A second 25% has evaporated or dissolved, according to government estimates. Another 25%, classified by the government as 'residual oil,' consisted of light sheens on the water, thick goo on the shore and tar balls. The tar balls, though not harmful to humans, are likely to wash up on shore for some time."
The last 25%, left out of the summary, is the most concerning. From the article: The final 25% of the oil — the equivalent of four Exxon Valdez spills —- is of greatest concern to scientists. It is drifting 3,000 to 4,300 feet below the gulf's surface, in vast clouds of atomized droplets that could alter links in the chain of life.
Big Dig-ing until the money is gone...
is there any GOOD reason why they simply didn't repair the blowout preventer, hook up a new dipstick, set up a new rig, and keep on a-pumpin'?
There's two answers:
1) The legal one is once a well goes out of control, it gets the death penalty. Sounds on the surface as stupid as punishing a gun instead of a shooter... however this "gun" cost BP within an order of magnitude of $100M to drill. Wells are really quite expensive to drill. This lowers the wealth of the world as a whole by $100M but more specifically it lowers the wealth of BP by $100M, thus being very motivating for funding groups like BP to hire drillers (TO) whom don't screw up.
2) The semi-technical answer is rapid, uncontrolled sand flow pretty much destroys the pipes and other down hole stuff. It would be way faster and cheaper to drill a new well than to repair this one. Its sort of the difference between duct taping something together in a movie plot therefore its possible vs actual business operation. What I'm getting at is testing and certifying casings and hangers and parts is really cheap when its on the surface, and really expensive when its buried in the earth.
