55 tons of methane EVERY HOUR

Wouldn't it be funny if the EPA was responsible for this too?

I remind you that the single biggest polluter in the USA is your venerated DoD

I hate atricles that say alarmist things like this:


the main component of natural gas, is 25 times more potent than carbon dioxide when it comes to climate change impact.

They should clarify what metric they are using for that claim, but it's an inconvenient truth.

What "metric" do you propose, obviously one that will say methane leaks, spills from extraction is inconsequential.

What is the 25 times measuring? It's a meaningless number for most people, but looks scary.

Please explain the methodology to us, how it is claimed the methane is 25 times more potent than CO2.

Can you?

Without cooking up a meaningless metric like they did, methane is actually less than half as strong as CO2.

So who’s to blame for a leak that cannot be stopped? Aging natural gas equipment may have contributed. According to documents filed (http://owr.conservation.ca.gov/WellRecord/037/03700776/03700776_DATA_03-19-2008.pdf) with the California Division of Oil, Gas & Geothermal Resources, this particular well, referred to as Standard Sesnon 25, was originally drilled in 1953, and showed signs of leakage 24 years ago, in 1992. Inspectors reported that they could hear the leak through borehole microphones.http://motherboard.vice.com/read/the-company-behind-las-methane-disaster-knew-its-well-was-leaking-24-years-ago

not clear if there is a reg demanding leak monitors to be on each well

yep, just old shit that, typically BigCarbon "runs it 'til in breaks" (BP pipeline in Alaska), no maintenance.

or like the San Bruno massive explosion and fire, PG&E did no check for faulty welding AND didn't keep good documentation.

and BigOil fellators bitch and whine about a few birds fried flying over concentrated solar plants.

If true, this clearly puts the fault in the hands of those knowing in high places, if they didn't get it fixed then.

High pressure cracks, leaks, etc. will slowly grow over time.

Still, we don't know all the details. This leak may have been repaired and this latest might be a new one. I doubt it wasn't inspected since those many years ago.

OK, here's what I don't get. If the Aliso Canyon storage has a storage of 86.2 Bcf and it can be withdrawn to users at 1,860 MMcfd to users, then why not just deplete the pressure by using this gas first? It's only a 46 day supply at max extraction rates. This time of year, it should be easy to do.

There is actually lots of information out there is you search it. Tests since that time have been good, suggesting the problem is fixed. Besides, at 500 ft. seems if that was the rupture, it would be easy to fix today.

There is the complete tif file of what was in your link:

Shazbot will love this.

On November 4th, Halliburton was authorized to rework the well:
