Giant Methane Leak in California Won't Be Capped For Months
Motherboard takes a look at the ongoing leak from a deep well in Southern California, and the engineering challenges that mean it won't be stopped for a while. From Motherboard's report:
An enormous amount of harmful methane gas is currently erupting from an energy facility in Aliso Canyon, California, at a startling rate of 110,000 pounds per hour. The gas, which carries with it the stench of rotting eggs, has led to the evacuation 1,700 homes so far. Many residents have already filed lawsuits against the company that owns the facility, the Southern California Gas Company. ... Part of the problem in stopping the leak lies in the base of the well, which sits 8,000 feet underground. Pumping fluids down into the will, usually the normal recourse, just isn't working, said [copmany spokesperson Anne] Silva. Workers have been "unable to establish a stable enough column of fluid to keep the force of gas coming up from the reservoir." The company is now constructing a relief well that will connect to the leaking well, and hopefully provide a way to reduce pressure so the leak can be plugged.
As the article notes, methane is an especially noxious gas in a figurative as well as literal sense; while it spends less time in the atmosphere than does CO2, it is more effective at trapping heat.
That would be hydrogen sulfide. Methane doesn't smell like anything. It's odorless; in fact your gas company puts a stinky compound into it so you'll know when there's a leak.

Great editing as always, timmay.
If it's really that bad, strap a flare to a drone and fly it into the methane exhaust.
Then maybe someone will take notice and actually do something about it, rather then this bullshit "oh well, ho hum, we'll drill another well as soon as we can" business-as-usual attitude. I'm guessing the facility is fully operational and pulling in profits for SCGC, despite the insane environmental harm it's currently causing? What incentive do they actually have to fix it right now? They haven't even confirmed if the secondary well will actually do anything.
Look at the prevailing atmospheric vorticity of the area, place a bunch of counter-vorticity-inducing stators around the biggest leak (just a few percent cant on them is sufficient) and light it up. The updraft will pull air in through the stators inducing continuous vorticity that will form a fire tornado miles into the atmosphere, totally oxidizing the methane and anything else that might burn in the gas.
Once the fuel supply is cut off, the vortex may be self-sustaining due to the temperature difference between the ground and the upper troposphere. This is known as an Atmospheric Vortex Engine.
To turn it off, you turn the stators straight in thereby removing the vorticity and the vortex structure dissipates into a normal updraft.
Seastead this.

So much for those who say the editors don't do anything anymore.

No. An accident is when you're drunk and you think you have to fart but you end up crapping your drawers.
When a leak in your natural gas storage facility springs a leak so bad that it makes an entire California town uninhabitable and the residents seriously ill, has already dumped the greenhouse equivalent of a million tons of CO2 into the atmosphere and you won't be able to stop the leak until at least March, 2016, it's a fucking crime. They should be frog-marching the CEO and Board of Directors of SoCal Gas in handcuffs right now. Let the hundreds of families that have had to leave their homes indefinitely throw rocks at their heads.

You are welcome on my lawn.
This article is pretty light on details. I know some of the residents in that area, and these are things some retired engineers have passed on to me from community meetings SCGC has had with them.
This is an old (early 20th century) oil field with over 80 wells. If you've never driven around LA, you may not know that there are still operational oil fields inside the city, but think of the La Brea tar pits, and it makes sense.
All of the wells in this field were designed to pump out oil. The pipes used in the wells are larger inner diameter than typically used with methane and have thinner and more porous wall material than typically used with methane. The pipes used are perfectly fine for oil, but would not be approved for a new methane well.
SCGC uses this underground cavern emptied of oil as storage for methane for Los Angeles in lieu of constructed tanks. They can and do pump methane in and out, it's all processed and comes from somewhere else.
What they did not do is verify that this old oil field will actually hold methane before they started using it. This leak looks like the methane is going through the porous concrete pipe that makes up the well and through the surrounding rock to the surface. This is why they can't seal the leak by clogging the pipe. It seems unlikely that anything short of capping all of the wells at the bottom or pumping out the methane will stop the leaking for good. They're halfway through drilling for one well, and don't intend to start on others until they show signs of leaking. All of their sensors are at ground level, so they will have no advance notice of an imminent leak.
The local schools have been closed due to air quality issues, and a few thousand people have been temporarily moved at SCGC's expense. This leak accounts for 25% of the total expected statewide carbon emissions.
It's a disasterous waste of a resource and many people have had to be evacuated, possibly for months. Why isn't there a serious response on the federal level instead of expecting the company to do whatever they can with their own resources? A spill in the gulf was dealt with on such a level.
Assuming it's pure methane, that would be ~23k BTU/lb, or about 2.5B BTU/hour.
At around $1.80 per Million BTU, that's about $4,500 worth of gas leaking out per hour. About $3.2M/month.
Not good, by any means, but I think dollars puts it into better scale.

Cowboy up. The world and no one on owe you anything.
So what you're saying is that the people affected by this problem should take the law into their own hands, and string those fuckers up? Because the world and no one owes them anything, like protection from those who would attack them?
