"Fossil Fuel" And The "Oil Window"

[OilIsMastery]

How many fossils does it take to make a barrel of oil?

According to the fossil fuel cult, oil can only be found in sedimentary rock and not below the alleged 15,000 foot "Oil Window." See so-called "Dr." Kenneth Deffeyes:

Hubbert's Peak

The next chapter of this book explains that there is an "oil window" that depends on subsurface temperatures. The rule of thumb says that temperatures 7,500 feet down are hot enough to "crack" organic-rich sediments into oil molecules. However, beyond 15,000 feet the rocks are so hot that the oil molecules are further cracked into natural gas. The range from 7,000 to 15,000 feet is called the "oil window." If you drill deeper than 15,000 feet, you can find natural gas but little oil.

http://www.energybulletin.net/2423.html

the temperatures at depths below about 15,000 feet are high enough (above 275 degrees F) to break hydrocarbon bonds. What remains after these molecular bonds are severed is methane, whose molecule contains only a single carbon atom. For petroleum geologists this is not just a matter of theory, but of repeated and sometimes costly experience: they speak of an oil “window” that exists from roughly 7,500 feet to 15,000 feet, within which temperatures are appropriate for oil formation; look far outside the window, and you will most likely come up with a dry hole or, at best, natural gas only.

Oil starts out as organic material, any kind of organic material, from algae to dead fish to organic material found in fish fecal pellets. This material must sink to an oxygen-free bottom where the absence of oxygen allows it to decay. Then it must be covered with other sediment and pushed into the "oil window" which starts at a depth of 7,500 feet deep and ends at 15,000 feet in depth. Above 7,500 feet, the temperature is not hot enough to "crack" the organic material into oil molecules and below 15,000 feet, everything is cracked all the way into natural gas. Inside that window, the temperature is at "coffee pot" levels and after a few million years, the organic material is cracked into oil.

http://scibooks.org/hubbert.html

Much of the book explains how heat "cracks" the complicated organic residues of dead plants to create oil. In general, the material must have, at some point, been trapped between 7,000 and 15,000 feet below the earth's surface. This is called the "oil window." Closer to the surface, temperatures are too low to make oil; deeper down, it is so hot that the material gets turned into natural gas.

http://mysite.verizon.net/vze495hz/id9.html

The oil window refers to the depth at which the process of turning kerogen into oil can occur – from 6,000-7,000 ft. to 13,000-15,000 ft. At this point our "source rock" (the original rock) will be "cracked" into oil. ("Cracking," apparently, is the term of choice used by petroleum geologists.) At greater depths you would not get oil from the cracking, but gas.

Geologists often refer to an "oil window"

They all say "geologists" plural but so far Deffeyes is the only so-called "geologist" I've found who has made such a claim (in other words the whole world is learning from this moron).

The reality is that oil rigs have been drilling below 15,000 feet true vertical depth looking for oil since 1938. And guess what else? They've found it!!!

InfoGulf.Com via Offshore Mag: Exploration and Development Below 15,000 feet TVD.

For exploration greater than 15,000 ft TVD on the shelf during the period 2003-2005, 115 wellbores (45 in 2003, 41 in 2004, and 29 in 2005) were drilled by 35 operators.

Those wells were drilled at least 3 years ago. We are finding oil much deeper now. According to Chris at Anadarko, the Grand Cayman well was drilled to 32,440 feet TVD. According to Guy at Transocean they've gone down to 35,000 feet TVD. And Transocean is building ships that will drill to 40,000 feet TVD.

Furthermore, 500 degree heat is no problem for oil: http://www.bloomberg.com/apps/news?pid=20601086&sid=aalWn.eJHGZk&refer=latin_america

They are talking about 400-500 b/d, that's barrels per day. About 3.8 Million b/d is required just to make up for decline in existing production.

Wrong thread. This is a thread about the alleged oil window and fossil fuel.

 

[spidergoat]

It's a pitiful amount though. It doesn't seem to contradict that oil reserves are found within a certain window.

 

[OilIsMastery]

It's a pitiful amount though.

Is Tupi a pitiful amount? 8 billion barrels. How about Carioca? 33 billion barrels.

It doesn't seem to contradict that oil reserves are found within a certain window.

You wouldn't know what contradiction is if you were personally tutored by Aristotle.

"The limit of 15,000 feet is the bottom of the oil window." -- Kenneth Deffeyes

 

[spidergoat]

Tupi field is found under about 4,000m of rock and salt. The Carioca field is at a depth of 2,410m. There can be exceptions because a "window" means: If you drill deeper than 15,000 feet, you can find natural gas but little oil. (from your quote) Little doesn't mean none.

 

[OilIsMastery]

Tupi field is found under about 4,000m of rock and salt. The Carioca field is at a depth of 2,410m.

So what? That proves that the oil window and biogenic origin are a hoax.

There can be exceptions because a "window" means: If you drill deeper than 15,000 feet, you can find natural gas but little oil. (from your quote) Little doesn't mean none.

So according to you the 8 billion barrels of oil at Tupi and the 33 billion barrels of oil at Carioca are actually natural gas but little oil. Interesting.

 

[spidergoat]

4,000M= about 13,000 feet

Obviously the Brazillian reserves are above the window because heat has not disintegrated the oil into methane. The petroleum geologists responsible for these finds also don't believe in abiotic oil. No one in the industry operates under that assumption.

 

[OilIsMastery]

Obviously the Brazillian reserves are above the window because heat has not disintegrated the oil into methane.

Obviously you don't have the slightest clue what your'e talking about. What temperature is required to "disinitigrate oil into methane?"

The petroleum geologists responsible for these finds also don't believe in abiotic oil.

Obviously you don't know any petroleum geologists.

No one in the industry operates under that assumption.

Everyone drilling under 15,000 feet TVD and into igneous rock operates under that assumption.

 

[spidergoat]

So then you reject the biotic theory, even though new discoveries might explain the presence of hydrocarbons at depth?

Research finds life 1000 feet beneath ocean floor

CORVALLIS, Ore. – A new study has discovered an abundance of microbial life deep beneath the ocean floor in ancient basalt that forms part of the Earth's crust, in research that once more expands the realm of seemingly hostile or remote environments in which living organisms can apparently thrive.

...Another very deep borehole was drilled in Gravenberg, Sweden in the search for deep earth gases. It reached 6800 m and here thermophilic bacteria were successfully enriched and isolated from a depth of 5278 m where the temperature was 65 - 75 °C.​

The absolute majority of boreholes explored for microbial life do not reach such depths because the drilling cost for a borehole increases with depth, which, together with increasing technical challenges limit the number of super deep boreholes to very few.

As far as the relationship between temperature and oil, here is a handy chart:

Why should oil under heat disintegrate into methane? methane exists with out oil.

http://physicsworld.com/cws/article/print/2487

It was not the Swedish oil that proved the most significant discovery though. Mixed in with the sludge at the bottom of the well, at a depth of over 6 km, was a large quantity of magnetite - a reduced form of iron oxide often associated with bacterial activity. After further investigation, Gold announced to the world that life exists not only on the surface of our planet but, in microbial form, deep inside the crust too.

The claim that the biosphere extends far underground was, if anything, even more heretical than the theory of upwelling hydrocarbons. At the time it was greeted with widespread scepticism. But I, for one, immediately found the basic idea plausible. As it happened, within a few years other researchers also obtained evidence for deep-living microbes, not only beneath the land, but also under the sea bed. Soon, microbes were being extracted from deep bore holes and cultured in the laboratory. Today there is no doubt that the underworld teems with life, as Gold asserted all along, although the precise extent of this subterranean realm remains uncertain.

 

[OilIsMastery]

So then you reject the biotic theory

What clued you in?

even though new discoveries might explain the presence of hydrocarbons at depth?

What discovery might that be?

That chart is absurd and based upon junk science. The 33 billion barrels of oil at Carioca is trapped by 500 degree heat.

Brazil Oil Trapped by 500-Degree Heat

 

[spidergoat]

The 33 billion barrels of oil at Carioca is trapped by 500 degree heat.

Of course, the pressure keeps it stable at that temperature. If it were to rise to shallower depths, it would fractionate.

Obviously the Brazillian reserves are above the window because heat has not disintegrated the oil into methane.

Like I said: you obviously don't have the slightest clue what you're talking about. First you said 200 degree temperatures disintigrate the oil into methane. Now you say that 260 degree temperature keeps it stable.

 

[pjdude1219]

Now you say that 260 degree temperature keeps it stable.

he said PRESSURE keeps it stable.

 

[OilIsMastery]

he said PRESSURE keeps it stable.

He doesn't even know what the pressure at Carioca is.

He clearly said high temperatures break apart oil into methane.

 

[spidergoat]

Temperature is a factor of depth, but it's variable. The temperature at which oil breaks down also varies with pressure. The 15,000 guideline for depth of recoverable oil still seems to stand.

In other words the universe is however you say it is even though the facts contradict your earlier claims.

do understand the relationships between volume, temperture, and pressure when dealing with fluids because you appear not to.

Yes I do. You don't even know what the temperature and pressure are at Carioca. I do.
