This week has brought us a sorry reminder that drilling for hydrocarbons is truly dangerous and like the airline business the best equipment and best crews can never completely out guess Mother Nature.
We maintain a column of drilling mud in the well to overcome down hole pressure, but not so much as to prevent drilling. It is a delicate balancing act that generally works very well. Yet entering a new porous formation is done with little if any certain knowledge of pressures to be encountered is fraught with risk.
When it goes wrong you have a blowout that brings a gas column up through the well and it must be shut in a quick as possible. It still can be managed with blowout preventers. It usually is managed.
However, in this case the worst happened and we had ignition. The men on the platform did not have time to understand that they were dead. The rest rolled overboard in seconds. Hours later the drilling ship sank and we presume it was pulled off the well head by then.
Of course the well head itself was not shut in so it is still spewing oil.
The only good news is that it blew up in the Gulf of Mexico rather than say the Arctic . That way Mother Nature will gobble most of it up fairly quickly. Of course fairly quickly may still work out to years.
I really do not think we can operate in the Arctic without at least an artificial island. A blow out there would be many times worse.
The worst week ever, brought to you by the fossil-fuel industry
30 APR 2010
It's a week to remember -- or better yet, forget. Who could have imagined such a confluence of terrible, horrible, no-good, very-bad events, rounding up what has to be the most disheartening "Earth Month" ever?
In what may soon be the worst oil spill in U.S. history, crude is gushing into the Gulf of Mexico and bleeding into Louisiana wetlands. The situation is so dire that ourbest environmental option is to set it ablaze. Eleven workers died when the rig blew up.
Economic disaster may follow ecological and human disaster, with the fishing, shrimping, and tourism industries likely to take a body blow. Remember when President Obama called for a major expansion of offshore drilling four weeks ago and said "oil rigs today generally don't cause spills"? How comforting.
Two coal miners were crushed to death in Kentucky
The Chinese coal freighter that crashed into the Great Barrier Reef a few weeks ago remains stuck and Australian authorities say the best option may be to sink it.
Even the week's good news -- the Obama administration's approval of Cape
Wind, which would be the nation's first offshore wind farm -- feels pretty bad. While offshore oil drilling proceeds merrily along with bipartisan support, it's taken nine years of torturous wrangling to get this far with Cape Wind U.S. Cape Cod ," quipped one climate reporter.
That's just this week. Looking back at the whole month of April, we had Massey's Big Branch mine disaster, another coal miner death in West Virginia, an oil refinery explosion in Washington state that killed seven workers, an 18,000-gallon oil spill from a Chevron pipeline into the Louisiana Delta, and, as mentioned above, a big oil spill at the world's largest continuous coral reef.
The connection running through every one of these disasters, of course, is dirty energy -- oil and coal. Only a fool would refuse to see the need to end our addiction.
Speaking of which, the U.S.
Leave it to a business professor to find a "silver lining" in the week's terrible news: "I think it may create some temporarily spikes in employment if the companies hire some local labor to clean up the spill," Rajesh Narayanan, professor of finance at Louisiana State University's business school, told The New York Times.
The craziest part is that our leaders continue pledging their tender loving care not to the natural world but to the GDP.
"Think of the language our politicians use," author and global organizer Bill McKibben said in a recent conversation. "'The economy is ailing.' 'It's hit a rough patch.' Or 'It's healing.' Or 'showing signs of healing.' I mean, we talk about it like you would your great aunt. But with the planet, it's 'natural cycles' and 'pay no attention.' 'The Arctic melted: must be a natural cycle someplace.'"
We're still acting as if the economy is the thing that's real, the thing with physical weight and force. We're acting as if the natural world is the abstraction, the intellectual concept that we can adjust to better suit our needs. That confusion will be the root of more disasters.

One additional comment should be made. The well is presently free flowing and that typically means that the production rate will decline far quicker than otherwise expected. Even to the point of a quick collapse as the well sands in.
I do not know anything about the reservoir characteristics but it will surely be a sandstone and likely in a horizontal configuration. This should make it terribly vulnerable to excess sanding in a free flow situation.
If we are lucky then, the well may simply reduce to a way more containable rate of flow.
