Stay safe.
In our old 50+ year old house, pipes in the basement were damaged with a 4 magnitude earthquake. Old buildings can suffer a surprising amount of harm.
California has laws that require structures that were built after a certain year to be strong enough to survive a certain level of magnitude, because it is a state that is subject to many, and powerful earthquakes. Call in when you have developed some compassion.
Au Contraire. I feel that DC is long overdue for about a 9.
Thanks a lot! My family and I live near there, as do a lot of Freepers.
At 4.5, no. At 5.8, which is what hit DC, yes. Huge difference in magnitude between 4.5 and 5.8, and while 5.8 would be no biggie in an area that has strict construction guidelines and zoning, it would truly huge in a place where quakes are a rare "surprise" like DC... and indeed would be a killer in those foreign lands where they build with mud and unreinforcerd concrete block..

Well, it's interesting to know that your "compassion" is restrained. We wouldn't want to go overboard on our caring for our fellow human beings, would we?
I should have read your mind and realized you wanted to know WHY, instead of the short answer I gave you.
Do NOT end up like Lot and his family!!!

**Proverbs: for some, silence is wisdom.
Actually, you gave me a wrong headed answer, the answer is yes.Yes: Earthquakes can fracture casings!
However that was not my question.
Repeat: It was not my question.I assume earthquakes can crack casings just as well as they can shear solid rock and crack steel beams. AND sice I live in earthquake country my question was about ground water contamination after a severe earthquake.
Which someone answered to my satisfaction:
oil pressures typically dont exceed column pressures.
Which leaves me to wonder what kind of goofball with no background educ. or specific knowledge would offer up to say ‘NO’ to a severe earthquake cracking pipe casings??
So I labeled it as ‘ignorant’ primarily for the benefit of others. I dont’ want you or anyone passing bad info. without being stopped or corrected.
Proverbs...
“Production pressures are usually considerably less, and pushing upward against the pressure exerted by the weight of the fluid column in the well, so by the time you get to the surface, the well may not even flow that high on its own and you have to pump the oil out.”
I can see the oil pressure not exceeding the column pressure.
But what about natural gas?
The burning off of excess gas, brightening the nighttime satellite photos,I’ve seen in the Bakken, is impressive. Must be some high gas pressure there.
You could blame old thunder thigh Michelle:)
But, evidently, not enough gas in volume to warrant the necessary infrastructure -- gathering system, gas plants and pipeline -- to exploit it.
I've read, though, that a "cottage industry" is forming around means of somehow employing this gas at the wellhead -- to run generators, pumps, etc.
>But, evidently, not enough gas in volume to warrant the >necessary infrastructure — gathering system, gas plants >and pipeline — to exploit it.
Why are you sending this to me? Sheez, another person who doesn’t even know what you are talking about .
This is really a bore for me....but here goes:
I’m well read on this subject. In a nutshell there is a gas glut in the U.S. . U.S. Law only allows for gas exports overseas by a few U.S. companies, currently this is all touch and go. Gas exports are restricted. Consequently, there is currently not a push to build infrastructure to capture and transmit this gas as it will depress prices even further. But eventually this will all sort itself out as US industries, electricty production and trasportation(buses,formerly diesel trucks) get on to natural gas in a big way, in addition to gas exports overseas ramping up over time.
Yuck!
>Sheez, another person who doesn’t even know what you are >talking about .
correction: Sheez, another person who doesnt know what they are talking about.
The amount of gas present in the oil varies from well to well.
While the pressures are no higher than the casing head pressure, the gas expands as it nears the surface, and until it can be linked to processing facilities by pipeline is burned off as a byproduct of oil production.
In the meantime, the oil is trucked out to shipment facilities and market, helping pay for the well while waiting on the pipeline hookup.
What you see in those night time pictures is the backlog in feeder pipeline construction: about 29% of the gas produced (as a byproduct of oil production) on any given day is flared, although that number is dropping as infrastructure construction catches up.
With multi-well pads, that backlog will diminish (fewer feeder lines needed), and less gas will be flared.
The amount flared is down to 29% of production versus the high of 36%, and progress is being made toward even lower numbers.
I thought #86 addressed that.
Which leaves me to wonder what kind of goofball with no background educ. or specific knowledge ...
I've wondered that myself.
