Greenhouse gasses from Fischer-Tropsch process used by Sasol

from

"Alternative methods

The process is today used in South Africa to produce most of the country's diesel fuel from coal by the company Sasol. The process was used in South Africa to meet its energy needs during its isolation under Apartheid. This process produces low sulfur diesel fuel but also produces large amounts of greenhouse gases."

This statement seem to be general and without a reference. Maybe it is worthwhile to explain and show the reader why gasification of goal will cause more greenhouse gasses than burning fuel oil. (In terms of the international effort to curb the release of greenhouse gases, this fact plays an important role in establishing the cost and benefits of alternative fuels (like biofuel))

--Jhdk (talk) 05:17, 14 July 2008 (UTC)

Given that, according to my sources, 1) Sasol produces only 28% of South Africa's fuels, and that 2) it also has a process to convert natural gas to fuels, the claim that it produces most of the country's diesel fuel from coal is dubious. However, it is true that the process produces large amounts of GHGs. I know of a coal-to-gas plant in North Dakota that pipelines the CO2 to a nearby oil field in Saskatchewan, where it is injected into the oil formation to improve oil recovery. Does Sasol do this? Probably not. Under the Kyoto agreement, South Africa is exempt from any GHG controls. RockyMtnGuy (talk) 14:38, 14 July 2008 (UTC)

Imports by US

Clearly the following info doesn't go here. Nor have I verified it so it could go anywhere!

• US supplied 41% of its own oil.
• Canada 12% (20% of all the oil the US imports)
• Saudi Arabia 7%/ 13%
• Venezuela 6%/11%
• Nigeria 6%/10%
• Mexico 5%/8%

But where would it go, if I can verify it? Student7 (talk) 13:32, 11 August 2008 (UTC)

Another global warming article

Why does every energy article have to end up being about global warming? Are the GW zealots so desperate that they have to include global warming in everything? Don't we have enough dedicated articles on global warming yet? It's outrageous! --THE FOUNDERS INTENT ^PRAISE 01:25, 17 September 2008 (UTC)

Well, the real answer is that it is the herd instinct. Much like sheep, people like to flock in the same direction. It avoids wasting a lot of energy thinking up new and original ideas, when you can have just one unoriginal idea and copy and paste it into every article.RockyMtnGuy (talk) 06:44, 2 October 2008 (UTC)

Please provide wp:RS source that petroleum is not related to global warming. NJGW (talk) 01:27, 17 September 2008 (UTC)

That is an example of the technique of answering a question by posing a counter-question which is irrelevant to the original question. He didn't say that petroleum was not related to global warming, he asked why people had to include global warming in every article. And that is a good question, since it does get repetitive after a while, and editors could always just say: :

See also: global warming

.RockyMtnGuy (talk) 06:44, 2 October 2008 (UTC)

I took the OP as requesting that any mention of global warming be removed from the article. I've seen plenty of vandals try to remove all the links from the various articles in the past. I agree though that there's no point in the repetition. I see no issue though in the current short and to the point paragraph in the environmental effects section. That's the only mention of GW in the very long article, so the OP's question is not really appropriate here. NJGW (talk) 06:55, 2 October 2008 (UTC)

Consumption

I was looking for the United States consumption rates of oil, and using the barrels/person/year, one gets a different number from using the barrels10^3/day. Anyone know what is up? PierceD —Preceding unsigned comment added by PierceD (talk • contribs) 21:41, 15 October 2008 (UTC)

That chart has issues. Don't quote it in your essays. Also, you should realise that consumption is defined differently in different places. We use about 20.6Mb/day of petroleum products (including oil and every thing else, we produce about 8.4, and net import 12.2) from EIA. NJGW (talk) 14:45, 16 October 2008 (UTC)

Article restructuring

Please note that (a) in this edit I have removed one long and unsourced consumption per capita table (with my badly spelt comment "removed tabe of energy consumption because it does not measure petroleum consumption, useful somewhere else maybe but bot here") and (b) with this edit I expanded the shorter consumption table, adding a per capita column, and (c) in this edit I merged the second consumption section up to the first, and (d) with this edit I did "move petroleum by country and consumption sections up above the sections on environmental effects and theories and alternatives". I am now removing the other large unsourced table, the one that lists countries by GDP divided by consumption. That idea could be added to the existing table as a new column, but I'm too lazy to do that now, so I have just moved it below here, in case anyone wants to try it themselves. -84user (talk) 20:52, 11 November 2008 (UTC)

Measure od Development?

Maybe the Barrel per year per cappita is a measure of development? I'm starting to think it's an excellent measure of development. The most industrialised countries obviously use more oil per cappita than a country that has no industry. This makes me think it should be a measure of development. If it is it should be added to the list of countries with ranking box, if its not; cool.

moved GDP table

There are two main ways to measure the oil consumption rates of countries: by population or by gross domestic product (GDP). This metric is important in the global debate over oil consumption/energy consumption/climate change because it takes social and economic considerations into account when scoring countries on their oil consumption/energy consumption/climate change goals. Nations such as China and India with large populations tend to promote the use of population based metrics, while nations with large economies such as the United States would tend to promote the GDP based metric.

Imports

Hmm the section on imports by country seems a little deceiving since it isn't talking about net imports. That is even though Canada exports more oil than it imports, it appears like an importer in the article. Would a map of net imports/exports not make more sense?

Please define the exact capacity of a barrel of crude oil

Is there a definative source for the exact capacity of a barrel?

I see various capacities, from 42 to 55 US gallons.

The NYMEX apparently doesn't even define the exact capacity of a barrel, even though they define everything else regarding the trading of oil:

http://www.nymex.com/CL_spec.aspx

And how is oil measured? How accurate are the flow meters or scales that are used during the transport of oil from the seller to the buyer?

Given the lack of an authoritative definition for the capacity of a barrel of oil, and the potential for different players to use different metrics over time (and for the potential of technologically inaccurate measurements) do we really have confidence in the historical record of past oil extraction and usage? —Preceding unsigned comment added by 69.159.219.48 (talk) 02:01, 16 June 2008 (UTC)

At the very top of that page they say US barrels and give the quantity in both barrels and gallons showing clearly what conversion factor they use. I dunno how accurate the meters are but I would be very surprised if thier inaccuracy significantly affected the trends. Plugwash (talk) 15:39, 16 June 2008 (UTC)

The exchanges don't and shouldn't get involved in measurement standards. In the US, trade is regulated by the Department of Commerce. They operate NIST who, on behalf of the Secretary of Commerce, are empowered to regulate the units of trade. Their definition for the barrel (petroleum) is 42 US gallons or exactly 158.9873 litres. See Barrel (volume). LeadSongDog (talk) 16:09, 16 June 2008 (UTC)

What do you mean "the exchanges don't and shouldn't get involved in measurement standards" ??? Of course it's not up to an exchange to DEFINE a standard, but since the NYMEX defines so many technical aspects of oil trade (when it's traded, where it's delivered, quality aspects (sulphur), etc) it's strange that they don't define the quantum or unit of trade in terms of STANDARD UNITS - such as by weight (lbs or kg), or by volume (cubic feet, yards or meters or gallons or liters). It's a CONTRACT, after all, and a good contract leaves NOTHING unexplained or uncertain. —Preceding unsigned comment added by 70.49.240.201 (talk) 14:30, 13 July 2008 (UTC)

As LeadSongDog said, it is the U.S. government that defines the size of the standard U.S. oil barrel. That that makes it an official STANDARD unit. NYMEX has no legal right to define measurement units, and doing so could result in it being fined. A contract only has to specify that it is using U.S. oil barrels, and that's good enough for any judge. RockyMtnGuy (talk) 14:55, 14 July 2008 (UTC)

If there is a credible link to a US Gov't definition for the capacity of a tradable barrel of oil, then it should be referenced in the main article. As the article states, there are several definitions for the capacity for a barrel (42 or 55 gallons). I highly doubt that the US gov't is or was responsible for defining the capacity of a barrel of crude oil used for commerce (or that it is a world-wide legal requirement to use a US-gov't definition) but if there is any such legal requirement then again a reference should be stated in the main article. To say that NYMEX has "no legal right to define measurement units" is a bogus argument. What NYMEX has is the right to define or specify units that are pertinent to trade. If NYMEX states that oil is to be traded in terms of barrels, then it is not "illegal" for NYMEX to state the capacity of this thing called a "barrel" in terms of unambiguous STANDARD units, or to point to an authoritative source (authoritative as far as NYMEX is concerned) that defines the capacity of a barrel. —Preceding unsigned comment added by 70.49.240.201 (talk) 01:37, 15 July 2008 (UTC)

See: U.S. Department of Commerce, National Institute of Standards and Technology, Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices, NIST Handbook 44, 1994 Edition (Washington, DC, October 1993), pp. B-10, C-17 and C-21. Finding a copy of it is your problem. The oil market is not a kindergarten, everybody trading oil knows what a U.S. petroleum barrel is (42 US gallons). 21:04, 15 July 2008 (UTC)

An oil barrel is 42 US gallons or 35 imperial gallons. There are also many other types of "barrel measurements", as seen here, but these are never used in the oil industry. I believe the 55 gallon you're talking about is defined here. The oil barrel measurements go back to the relatively small barrels they used "back in the day" when oil was put in wooden casks and then trucked out by horses (driven by teamsters). The term is vestigial in that barrels haven't been used to store oil since the days of Spindletop if not before (they are very messy, inefficient and totally inadequate for anything but the smallest volumes if you think about it), but the oil industry has a lot of funny units and terms it has adopted based on its history rather than scientific rigour. TastyCakes (talk) 15:27, 31 December 2008 (UTC)

At first in Oil Springs, Ontario, they would float wooden barrels down ditches or Black Creek to avoid the impassible roads.[1][2]LeadSongDog (talk) 18:55, 31 December 2008 (UTC)

And it gets worse. In the article List of oil spills, the measurement is tonnes (or metric tons). So one has a reasonable expectation to have the writers define why the uses their chosen measurements. Is crude oil, or petroleum, a product measured by volume or by weight? As of this date, we are only hearing the use of 42 gallon barrels and gallons as a measurement of the Gulf of Mexico's current BP spill. - KitchM (talk) 20:45, 21 May 2010 (UTC)

Composition of Petroleum

There seems to be some confusion in this article regarding the makeup of what is called crude oil, or petroleum. In one place they are seen as equal, although mentioned as usually containing natural gas as well. But it is mentioned that natural gas is one or more hydrocarbons, and crude oil is an accumulation of various hydrocarbons, so one may reasonable question why the petroleum is only partially hydrocarbon. So which is it; hydrocarbons or only part hydrocarbons? If only part, it should be clearly defined as to what makes up the rest. Is petroleum also called crude oil? Can't it be simply said that it contains hydrocarbons of various types in various states, and that is what makes up the quality of any deposit of petroleum? IMHO, the layout of this part of the subject needs to be clarified and condensed into one place early on. - KitchM (talk) 20:55, 21 May 2010 (UTC)

Empirical equations for the Thermal properties of petroleum products

Heat of Combustion: At a constant volume the heat of combustion of a petroleum product can be approximated as: $Q_{v}=12,400-2,100d^{2}$ where $Q_{v}$ is measured in cal/gram and d is the specific gravity at 60°F.

Thermal Conductivity The thermal conductivity of petroleum based liquids can be modeled as: $K={\frac {0.813}{d}}[1-0.0003(t-32)]$ where K is measured in BTU per hour per square foot and °F per in and d is the specific gravity at 60°F.

Specific Heat The specific heat of a petroleum oils can be modeled as: $c={\frac {1}{\sqrt {d}}}[0.388+0.00045t]$ where c is measured in BTU/lbm-°F, t is the temperature in Fahrenheit and d is the specific gravity at 60°F. ~ Latent Heat of Vaporization The latent heat of vaporization can be modeled under atmospheric conditions as: $L={\frac {1}{d}}[110.9-0.09t]$ where L is measured in BTU/lbm, t is measured in °F and d is the specific gravity at 60°F.

I did this just now for specific heat and latent heat of vaporization. Should be right, but please double check my arithmetic anyway.

Shouldn't the "per square foot" be "per foot?" --Vaughan Pratt (talk) 23:01, 1 January 2010 (UTC)

Wouldn't it be per cubic foot, as opposed to "per square foot" or "per foot?" We are, after all, discussing a fluid. Or, since we are discussing thermal conductivity, would the square foot be appropriate as the area in contact with the medium to (or from) which heat is being conducted would (in most cases I can think of anyway) be two-dimensional? I've gone and truly puzzled myself :) !! Spiral5800 (talk) 08:21, 4 July 2010 (UTC)

Formula of Latent Heat of Vaporization is correct in Brittish units and SHOULD BE DIVIDED BY 1.8 to get the indicated kcal/kg metric equivalent. Instead it has been multiplied (with mistakes) by 1.8. I do not know how to correct in the text. Correct formula anyhow is L=1/d*(66.1-t/20) if I am not mistaken. — Preceding unsigned comment added by Sp2orbital (talk • contribs) 20:53, 21 March 2011 (UTC) Formula of CP seems correct in British units and IT SHOULD BE EXACTLY THE SAME in Kcal/kg/K.

Peak Oil

The year Hubbert predicted for world peak oil was 2006 by my reference. This article says 2000, which is trying to influence a POV against Peak oil methologies, which have proven to be fairly good. For example texas/lower48 US was predicted very well by Hubbert. Perhaps this section should be re-written by a semi-expert on the area of peak oil, since the anti-Peak oil POV seems more apparent in my reading of this article. —Preceding unsigned comment added by 128.32.166.162 (talk) 18:59, 1 October 2010 (UTC)

p. 38 of 1956 paper, hubbert states, "... On the basis of the present estimates of the ultimate reserves of petroleum and natural gas, it appears that the culmination of world production should occur within a half a century, whil the culmination of petroleum and natural gas in the both the United States and the State of Texas should occur within the next few decades. ..."

Both of these accounts are actually quite accurate for Texas and for world production of oil, where the former occurred in 1970 and that later occurred (in yearly production terms) in 2005.

I would like to see a revision in this article to reflect the scholarship of Hubbert, which is being maligned by skewing the numbers. Hubbert made graphs yes but the text describing these peaks is not as precise as reflected in the wikipedia article, making the predictions into straw men for the wiki author to shoot down.

My advise is to revise to reflect the scholarship, since this is an encyclopedia. —Preceding unsigned comment added by 128.32.166.162 (talk) 19:19, 1 October 2010 (UTC)

Crude oil and petroleum - whats the difference

"The lead says petroleum or crude oil is a naturally occurring," but later it says (section composition) it says "In its strictest sense, petroleum includes only crude oil, but in common usage it includes all liquid, gaseous,".

The use of fossil fuels such as petroleum can have a negative impact on Earth's biosphere, releasing pollutants and greenhouse gases into the air and damaging ecosystems through events such as oil spills.

If global warming and increased CO2 concentrations occur, this could be perceived as having a positive impact on the lives of most plant life, species adapted to desert climates, and even humans living in high latitude geographies. The article should instead be written to describe what specific actions have been proven to occur as a result of petroleum combustion.--Dikteren (talk) 16:53, 23 April 2012 (UTC)

I second Dikteren's concerns. Said paragraph also lacks any citations. --Adam9389 (talk) 15:41, 01 August 2012 (UTC)

The third (and completely un-cited, but I digress) paragraph on negative environmental effects just seems so remarkably out of place, considering that the intro should be an overview as to what petroleum is. Seeing as how nobody's contributing any further to this discussion, I'm taking the initiative and moving it down to its real home in the intro to the 'Environmental effects' section. If anyone sees a problem with that edit, bring it up here like civilized editors (I have no stomach for edit wars). --Adam9389 (talk) 10:49, 08 April 2013 (UTC)

I just reverted this change. The WP:LEDE summarises the article, and this is the summary of a whole set of sections. Also, according to that guideline page, the summary in the lede does not need citations as the main statements are to be cited where they appear in the body of the article. Two people commenting a year apart do not a consensus make. --Nigelj (talk) 18:50, 8 April 2013 (UTC)

More on the theory of abiotic/abiogenic oil formation

I read the "canadafreepress" article talked about and rejected in the discussion on abiogenic oil below, and I agreed that it didn't provide sufficient support for the abiotic idea.

It would seem, though, that this might: http://www.csun.edu/~vcgeo005/Energy.html

It's a scholarly article that cites its sources thoroughly.

I originally accessed that article through this one:

http://www.americantraditions.org/Articles/Are%20Coal,%20Natural%20Gas,%20and%20Crude%20Oil%20Really%20Fossil%20Fuels%20and%20Is%20There%20Really%20Any%20Oil%20Shortage%20of%20Oil.htm

It's from a less reputable source, but it does do a good job of compiling evidence that amounts to grounds for a debate about the true origins of oil. It seems that if nothing else, the wiki article on petroleum should include some notice of this debate and a link to the abiotic oil Wiki page. Djminkus (talk) 01:47, 12 December 2012 (UTC)

Unless there's serious evidence that the scientific community sees abiotic oil as anything but wp:FRINGE, there's no reason to include it here. LeadSongDog come howl! 16:24, 23 May 2013 (UTC)

Picture

I think the article would benefit from a picture of unprocessed oil, since the first three pictures in the article are about production, not the substance itself. (something like the Coal page). This page has an example of what kind of picture I am referring to, but obviously we need one with the right permissions on it: https://courseware.e-education.psu.edu/courses/egee101/L05_petroleum/L05_quality.html

Alternatively, a picture of unprocessed oil (like from a groundswell) would work as well for effect StarDolph (talk) 22:48, 22 January 2014 (UTC)

Formula for thermal conductivity of crude oil

There is no citation - does anyone know where this comes from?

The formula has 0.547 at the end looking like an exponent, but this would not work for modest temperatures, as the term 1 - 0.0203(t-32) soon goes negative. How is the 0.547 to be used?

It would be good to have this and the following formulae in SI units.

I found a more accurate Cragoe Equation on the link I referenced and I updated the equation. Though it spits out an answer in a really weird unit BTU*in/hr/ft^2/F, it matches other sources for oil thermal conductivity — Preceding unsigned comment added by 216.74.233.146 (talk) 20:59, 26 February 2014 (UTC)

Graphs need to be updated

Oil producing countries: the "Canadian provinces producing oil" needs to add British Columbia since it produces 1.2% of Canada's oil - nearly as much as Manitoba - and to drop Ontario because it now only produces a miniscule 0.04% of Canada's oil (100 years ago it produced most of it, but production has declined a long, long way since then). Alternatively it could add Nova Scotia (0.6%) and Northwest Territories (0.3%).

Oil imports to US 2010: needs to be upgraded to more recent data. In 2013, only Saudi Arabia (485 million bbl) and Mexico (335) would still be red. Venezuela (294) would be downgraded to orange, while Iraq (124), Kuwait (120), and Nigeria (102) would be downgraded to yellow. Canada should be upgraded to bright purple or some such color since it exported a massive 1,147 million bbl to the US, or about a quarter of US imports.RockyMtnGuy (talk) 17:27, 20 October 2014 (UTC)

Cyberbot II linked to an archived version that was still dead [3]; I changed it to an earlier archive with the correct document. Altamel (talk) 17:43, 27 August 2015 (UTC)

"A fossil fuel, petroleum is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and subjected to intense heat and pressure."

What a crap. There was never so much plankton and algae combined and biomass overall on Earth compared to how much oil has been produced.--Reciprocist (talk) 13:30, 12 September 2015 (UTC)

Maybe there wasn't on Mars or whatever planet you have been living on, but here on Earth the amount of organisms which have died and been buried over the last several billion years has been truly astronomical. A lot of the organic material deposited on sea bottoms has been converted to petroleum by heat and pressure over that time period. When I worked for an oil company, we tried it in the lab and it only took about a week to turn plankton into oil, but nature operates more slowly. Although over the eons 99% of the oil has leaked to the surface and been destroyed by bacteria and weathering, there's still an awful lot of it left down there. Where I grew up we had about 5 vertical miles of organic rock deposits under our feet, and from an oil company perspective, it was pure heaven and very lucrative for my career. Of course, if you believe the Earth is only 6,000 years old based on some dubious biblical interpretations, then this explanation will not convince you. If so, go away and move to some much younger planet. RockyMtnGuy (talk) 22:25, 13 September 2015 (UTC)

Shouldn't the article mention that at least some oil is abiogenic (formed by inorganic means)?

http://www.livescience.com/9404-mysterious-origin-supply-oil.html

Abiogenic sources of oil have been found, but never in commercially profitable amounts. The controversy isn't over whether naturally forming oil reserves exist, said Larry Nation of the American Association of Petroleum Geologists. It's over how much they contribute to Earth's overall reserves and how much time and effort geologists should devote to seeking them out.— Preceding unsigned comment added by 194.1.145.253 (talk • contribs) 20:02, 4 January 2016 (UTC)

The article does briefly mention the theory of abiogenic petroleum origin. But generally, abiogenic sources are believed to be inconsequential. The livescience.com webpage you link exaggerates the issue. ChemNerd (talk) 20:02, 4 January 2016 (UTC)

The article leaves the impression that all oil is of organic origin. How is a claim that some oil is abiogenic, an exaggeration? — Preceding unsigned comment added by 109.64.70.120 (talk) 08:58, 15 January 2016 (UTC)

That's not what I said. I said the livescience.com article exaggerates the issue. To be more specific, it conveys the idea that there is more of controversy than there really is. ChemNerd (talk) 13:12, 15 January 2016 (UTC)

The livescience.com article is all BS (Bad Science) - discredited 19th century Russian theories and popular myths (oil comes from dead dinosaurs, prehistoric comets, volcanoes, exists in vast pools, takes hundreds of millions of years to form, etc). Virtually none of the oil on Earth is of non-biological origins (unless you classify methane as "oil"). Since the 1950's petroleum geologists have rather accurately determined how and where oil was formed. Vast amounts have been created from dead organisms since life originated on Earth billions of years ago, but 99% of it has escaped from the earth and been biodegraded into new life, so geologists are looking for the 1% that is left underground. You can become rich if you can only find it. The real trick is finding out where it is now, since oil is very mobile and can move several kilometres vertically and hundreds of kilometres horizontally from where it originated. The shale oil revolution is somewhat different in that the oil is still in the marine shale formations where it originated, and the real challenge is producing it economically using horizontal drilling and multistage hydraulic fracturing, but that's too complicated for the popular press. RockyMtnGuy (talk) 17:35, 16 January 2016 (UTC)

Also, people seem to be fond of citing "Larry Nation of the American Association of Petroleum Geologists", quoted out of context of a couple of decades ago, as being authoritative. Let me mention that Larry Nation is the former Communications Director of the AAPG, and has a degree in Journalism. Let me also mention that he said about the late Thomas Gold's abiogenic theory, "We're very familiar with Tommy Gold. Geologists in that field are more open-minded than you might think. They're a pretty independent bunch, or there wouldn't be so many dry holes." and also, "Most petroleum geologists don't agree with his theory, but it's fun to talk about." Gold, on the other hand, was not a petroleum geologist but an Austrian astrophysicist also known for proposing the Steady State theory of cosmic origins, now rejected by the vast majority of astrophysicists in favor of the Big Bang theory.RockyMtnGuy (talk) 18:14, 16 January 2016 (UTC)

The question is not about quantities or percentage. The article, as it is today, works very hard to leave an impression that absolutely all naturally occurring oil is of biogenic origin. Which is not true. — Preceding unsigned comment added by 194.1.145.253 (talk) 12:04, 18 January 2016 (UTC)

I would say that the percentage of abiogenic versus biogenic oil in the world today could be rounded to approximately 0%. If you want to quote a higher number, you need to come up with an authoritative source for it, and not somebody's fringe theory. I would say Gold's abiogenic theory would fall into the fringe theory category given the most recent data on the subject. Just about all petroleum geologists reject it. RockyMtnGuy (talk) 21:56, 18 January 2016 (UTC)

You continuously reference some fringe theories, and (successfully) explain why they should not be present in the article. Kudos for that. However, this is not what I am asking. There is no dispute in the scientific community that at least some naturally occurring oil is of abiogenic origin. And the article, as it is today, works very hard to leave an impression that absolutely all naturally occurring oil is of biogenic origin. — Preceding unsigned comment added by 194.1.145.253 (talk) 07:47, 19 January 2016 (UTC)

(edit conflict) The article on the topic says in its summary (lead section) "Scientific opinion on the origin of oil and gas is that all natural oil and gas deposits on Earth are fossil fuels, and are therefore not abiogenic in origin". I would suggest discussing it there. Here we want only a summary of the summary, and the conclusion of our resident experts seems to be that it is a fringe theory, and so not worthy of undue general coverage. --Nigelj (talk) 07:51, 19 January 2016 (UTC)

Origin and Formation of Petroleum

Natural gas contains all the noble gasses (He, Ne, Ar, Kr, Xe, Rn). Some gas wells contain as much as 4% helium. The noble gasses are chemically inert and are not found at all in plankton nor any other biological life. The only source of the noble gasses is nuclear reaction. Natural gas and petroleum find their origin in the nuclear reactions happening in the center of the magma sphere. From this center the gasses make their way to the subsurface of the Earth's crust, and finally become trapped beneath shale and slate deposits as well as beneath the thick frozen ice of the arctic plain. — Preceding unsigned comment added by My Flatley (talk • contribs) 02:13, 5 November 2018 (UTC)

1. You really should get into the habit of giving sources.
2. What do you mean by "center of the magmasphere"? "Magmasphere" is customarily defined as "a sphere of magma at the center of a rocky planet or moon of sufficiently large size." The center of Earth is largely solid iron and nickel. There is nothing "spherical" about magma, which is found in the crust at plate boundaries and at hot spots like Hawaii and Yellowstone. A magma chamber might be somewhat spherical but this is by no means necessary.
3. "Natural gas and petroleum find their origen in the nuclear reactions". Since petroleum consists primarily of various hydrocarbons and some oxygen, much more likely is that they find their origin in heat and pressure combining those elements. The heat itelf may originate from nuclear reactions as per Rutherford's explanation but the petroleum itself need not be formed anywhere near nuclear sources of heat since the geothermal gradient exists at other sites besides those bearing radioactive ores. It may however be reasonable to infer that those wells that are rich in noble gases are near such ores. Vaughan Pratt (talk) 19:55, 22 March 2019 (UTC)

Why was it merged?

So there used to be separate articles , crude oil and petroleum .. Would it not have made sense to have kept both and skewed the content into either... 'where it occurs, subtypes (brent etc), drilling, discovery, formation' == crude oil. 'refinement, uses,...' == petroleum . Of course both articles would quickly mention the other. Do people really prefer these huge articles.. surely the beauty of a wiki is the ability to browse and zoom in on a specific piece of information

Fmadd (talk) 12:28, 14 February 2017 (UTC)

Absolutely correct, these should be separate articles. This article incorrectly defines petroleum as a liquid, when in fact the definition covers solid and gas forms of complex hydrocarbons. I was led here due to the peak oil article referring to 'petroleum deposits' which seemed strange to me, when oil deposits would make more sense. This article implies that petroleum is the correct term for crude oil, when it would be more accurate to say crude oil is a type of petroleum. https://www.glossary.oilfield.slb.com/Terms/p/petroleum.aspx Bertcocaine (talk) 11:17, 8 October 2018 (UTC)

Elsewhere in the solar system, specifically on Saturn's largest moon Titan, lakes of liquid hydrocarbons comprising methane, ethane, propane and other constituents, occur naturally. Based on data from the space probe Cassini, scientists announced on February 13, 2008, that Titan hosts within its polar lakes "hundreds of times more natural gas and other liquid hydrocarbons than all the known oil and natural gas reserves on Earth." The desert sand dunes along the equator, while devoid of open liquid, nonetheless hold more organic material than all of Earth's coal reserves. It has been estimated that the visible lakes and seas of Titan contain about 300 times the volume of Earth's proven oil reserves.

Thank you. 31.4.128.86 (talk) 14:07, 30 November 2021 (UTC)

 Not done for now: please establish a consensus for this alteration before using the {{edit semi-protected}} template. I don't think that prose really fits there, as there is no mention of the formation of those hydrocarbons in the suggested prose. ScottishFinnishRadish (talk) 14:24, 30 November 2021 (UTC)

Hope the more concise prose now meets with the editor's approval. Best to put this modest section in the article and kick off the discussion (if any) that way, rather than enter a minefield (or oilfield?) of discussion on the Talk page with editors who are good on nitpicking formalities but inexperienced in astronomy. Thank you. 31.4.128.152 (talk) 16:16, 30 November 2021 (UTC)

I agree with User:ScottishFinnishRadish that this would be misplaced where you propose to place it, which is a section on how petroleum forms on Earth. It is a candidate to go in a new section on "Petroleum on other worlds" or some other suitable title, later in the article, assuming there is consensus that the hydrocarbons on Titan actually fit the definition of petroleum. What is present on Titan sounds more like liquified natural gas, if that.

Also, FWIW: As I mention on my user page, I hold a Ph.D. from Caltech in astronomy. I acknowledge this is nowadays somewhat separate from planetary science. Regardless, it is probably best not to assume that editors who disagree with your suggested edits do so out of obstinate ignorance. --Kent G. Budge (talk) 16:36, 30 November 2021 (UTC)

I agree with all you say, on oils, on ignorance etc. So please call the header "Hydrocarbons on other worlds". And then experts such as yourself can engage on Wikipedia over the next few weeks, months and years what relevance this has to hydrocarbons on Earth. Be bold. 31.4.128.152 (talk) 16:48, 30 November 2021 (UTC)

I like "Hydrocarbons on other worlds" as a header. With that title, I agree with adding it to the article. --Kent G. Budge (talk) 17:10, 30 November 2021 (UTC)

Great. Kindly consider a mention of Titanic lakes of hydrocarbon in the lead. Not immediately perhaps, but after reflection.31.4.158.55 (talk) 20:31, 30 November 2021 (UTC)

Large edits, March 2022

• I removed almost all of the history section. We have a separate article on that subject.
• I removed all of the section on various physical chemical analyses which can be applied to many compounds.
• I hypothesize that the majority of readers visit to learn about what it is (composition) and how it is converted to stuff we use (refining).

Hi @SmokefootSmokefoot -- did you make sure that the history section citations were forked into the history article -- it seems slim, and I am not comfortable with that bit being removed. Other edits look good.Sadads (talk) 22:16, 26 March 2022 (UTC)

Oh.... Let me do some work, getting the removed content properly relocated. In the meantime I will reinstate. --Smokefoot (talk) 00:07, 27 March 2022 (UTC)

@Smokefoot Great! We can also use {{excerpt}} to bring over the lead of the history sub article as well -- so if the lead is good, we can remove all the content that needs to be maintained here. Sadads (talk) 21:49, 27 March 2022 (UTC)

Why are there two sections both called "composition"

176.111.214.208 (talk) 08:42, 14 April 2022 (UTC)

The second Composition section was titled Chemistry up until March 26. I've restored the previous section title. I'm guessing there may have been an intent to merge the two sections, but this was never finished. --Kent G. Budge (talk) 13:56, 14 April 2022 (UTC)

Negative slant of lede

It is bizarre that the entire last paragraph of the lede is about the negative effects of petroleum but no where in the lede does it mention that, oh you know, petroleum is one of the largest drivers of modern civilization and human wealth, responsible for literally hundreds of millions of lives saved. Like by all means the article should discuss the downsides, but some perspective is seriously needed. 73.70.48.139 (talk) 01:38, 12 November 2022 (UTC)

Agreed. There's a fair bit of duplicate statements couched in different wording as well, lending to its apparent length. I'll take a crack at it. cheers. anastrophe, an editor he is. 05:57, 12 November 2022 (UTC)

Modern history section contradictions

https://en.wikipedia.org/wiki/Petroleum#Modern

This section is confusing because it contains at 3 conflicting claims for the world's first oil refinery, only one of which is sourced. If you search the section of text for 'refinery' they are the only results. Yoweigh (talk) 15:17, 11 September 2023 (UTC)

To add to article

In order to help make this article more properly encyclopedic, shouldn't we add exactly when the earth's petroleum deposits were formed? To my knowledge, 70% of oil deposits existing today were formed in the Mesozoic period, 20% were formed in the Cenozoic period, and 10% were formed in the Paleozoic period. In the current version of this article, neither the names of these three periods nor how many millions of years ago they were are mentioned, but these seem like basic facts that anyone reading this article would expect to find here. How is it that this basic information was left out? 98.123.38.211 (talk) 06:27, 25 November 2023 (UTC)

"derived from fossilized organic materials"? Petroleum is hydrocarbons, not minerals.

A fossil is usually understood to be mineralized or permineralized, turned to stone so to speak. Aren't fossils a result of organic material being preserved and thereby NOT becoming petroleum? Petroleum is mainly hydrocarbons so does that really count as fossilization as it's commonly understood? I think that phrasing is either inaccurate or at the very least misleading to the average reader. 95.91.250.144 (talk) 17:53, 9 January 2024 (UTC)
