Silent earthquakes are tied to changes in fluid deep below Cascadia's fault

Cascadia’s fault!

[HighSierra5]

Nothing more humbling than a large earhquake jolting you out of you’re daily “problems”. It’s God’s way of letting you know that he’s in charge.

Mother Earth is manufacturing more petroleum through abiotic means. Supercritical carbon dioxide and superheated water, under the conditions of temperature and pressure, are forming hydrocarbon molecules at an enormous rate, on a scale unimaginable for even the largest and most advanced industrial thermal pyrolysis plant that could be conceived.

And here you thought petroleum was just some kind of dinosaur soup.

[crusty old prospector]

You need a lesson in hydrocarbon generation, migration, and accumulation. Maybe even a junior high science class. You really, really, think that oil is stable within the earth where the temperature is over 1000 degrees? Ever heard of a refinery?

[reluctantwarrior]

Maybe you should read the russian reports on abiotic oil, the crust and mantle are creating “crude” everyday.

No thanks. I believe I know where oil and gas come from and it ain’t the mantle. Every known accumulation of hydrocarbons is found in sedimentary basins or their margins. Want to know why no one has ever found oil in Iowa or Minnesota? Or Wisconsin or Maine? Because they have always been “high” and never had much sedimentary cover deposited on them. No source rocks, no oil. You can derive methane from coal beds but those areas also lack those.

[reluctantwarrior]

So the science is settled then? Dinosaurs and plants turned into oil? You might want to re-open that closed brain of yours and consider that Petrobas finds oil at 46000 feet how did the animals get that far under the ground? The sediments above these finds arent as old as the dinosaurs another hit to your its all dino soup theory. If dino’s turn to oil it wouldnt require sediments a probiotic process would make oil regardless.

What? No blame of fracking?

[crusty old prospector]

First of all, no one said anything about dinosaurs. Oil comes from algae. Dinosaurs lived primarily on the earth. Ever see what happens to an animal such as a cow when it dies on the earth? It is consumed. If not by carrion eaters then by worms if it is buried. I think you also need to check the total depth on the Petrobras well. It is probably an extended reach directional well from an existing platform. My guess is that its true vertical depth is around 20,000’. The deepest well in the world is in the BP Tiber Field in the Gulf of Mexico. 35,056’.

[reluctantwarrior]

Algae doesnt form at 20,000 feet to use your data, if you are saying giant oceans of algae formed then were covered with sediments then why wouldnt that process still be at work? Why wouldnt the subduction at the mid ocean ridges that pull in vast amounts of sea water also be capturing giant algae blooms and probiotically making more oil?

The oil made by algae in the lab isnt chemically the same as crude oil, why not?

[crusty old prospector]

Algae and other microorganisms live at the surface in the photic zone of all oceans. They have a calcareous or siliceous shell. When they die, they fall to the bottom of the ocean. The bottom of the ocean is typically anoxic, which means your usual cast of bottom feeders cannot survive. This allows the algae and other microorganisms to accumulate. Now bury this pile of mush down to a minimum of 7,000' and viola, you get oil.

I am not sure what you are referring to as to the laboratory experiment. Oils are different. Some are waxy (paraffinic.) Some are asphaltic. Some are aromatic. Much of it has to do with the depth of burial of the source rock. There is no one "oil."

Thanks BenLurkin. Cue the Big Joe Turner, Bill Haley, and Elvis.

So oil is formed probiotically by algae shells, ok. but why is methane hydrates at depth in the crust forming oil abiotically? Why do capped wells refill? Both can be at work and I am not sure algae blooms even ocean sized could produce as much crude as we have extracted and are still extracting. Yes many types of oil which is formed by algae, which is formed by abiotic process. Not sure one algae process would produce a broad class of hydrocarbons but please keep promoting algae. I believe the Russians have it right

Silent But Deep

Methane is an easy molecule to make. Just ask Venus. It is all over the universe. Some comes out in the earth in volcanos. But oil, meh? And capped wells do not refill. If it were that easy, I could just buy up some old wells and wait for that happy day. There are only about a million or so in America. I’m sure that you will soon reference Eugene Island 330. That has a very simple explanation. As the reservoir was drawn down, the trapping fault opened up and hydrocarbons from a deeper reservoir travelled up the fault and briefly recharged the reservoir. It is thrown out there ever time by the abiotic people. There are only several thousand other oil fields worldwide that this has never occurred.

[reluctantwarrior]

Google refilling wells, hate to burst your overconfident bubble, it is happening and many wells are back in service. You really are an arrogant know it all that since your view must be right fails to believe in any contrary facts. Glad you are not in charge of any real sciency stuff, grow your algae and good luck. The permian has hundreds of non fracked wells that are back in service. You are insufferable, hope you arent a science teacher, Mr. Settled SCience

[crusty old prospector]

Ha ha. Refilled wells. I bet you believe in the Tooth Fairy, too. Maybe even the Easter Bunny. May I ask what you do for a living? As for myself, I am a petroleum geologist.
