The contents of the Crude oil page were merged into Petroleum. For the contribution history and old versions of the redirected page, please see its history; for the discussion at that location, see its talk page.

A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock under anoxic conditions and subjected to both intense heat and pressure.

The article was quite well researched, easy to read, neutral and large subjects such as History and Industry were linked properly ( History of the petroleum industry and Petroleum industry) to larger and more complete articles on such subjects. However, certain subjects were found a bit lacking.

-Images are plentiful with proper annotations, sources comes from diverse authors and the article itself is high importance in climate change, environment and energy.

- The Introduction displayed not all of information content found in the article. There is a certain imbalance of subjects found in the introduction. The introduction content was putting forwards more into its exploitation and its usage. Subjects such as the formation of petroleum, history and others were to be serverely lacking in the introduction. Other subjects found later in the article such as alternatives, environmental effects, and classifications were rushed and only covered by 2 to 3 sentences around the introduction.

-The History of Petroleum should be more define in its timeframe. The subject is cut into two parts, early and modern, it can be quite confusing for people that needs a proper timeframe. The earliest timeframe in early is 4300 years and for modern is 1847. Both time estimates in this subject can be better classify such in a more precise but still in a generall timeframe. Such as:

4300 years

2000 years

347 CE (AD) years

7th century

12th - 13th century

1415 - 1450

18th century

. . .

Also, as discused in Talk, (Talk:Petroleum), an added section for prehistoric timeframe would be most beneficial for the history subject.

-Almost all sources were well placed and used efficiently. All were linked to proper sources such as wikipedia But, certain sources needs to be updated and changed.

At the introduction, geological formations linked to a wikiedia aticle that explained geological formation properly but it had no mention of petroleum within the article.

Certain information can be updated. Due to how the world and the market is constantly changing, the petroleum prices and trade doesn't stay the same. It is understanble and should be updated for further research and completion.

At the subject trade, there is a lack of sources representing Nymex exchange and its exchange rates. New York Mercantile Exchange and even Chicago Mercantile Exchange should be added as additional sources and beneficiary aid for others.

-At subject environmental effect, 'others say that fossil fuels increased whaling'. Such line has a lack of source, this sentence goes against the saying of the content within the subject, 'petroleum-refined kerosene saved some species of great whales from extinction'. Probably adding a bit more information or just comprosing this part of the article to later add within another part more focused on animals. A section only for whales is not too imperative to feature an only section,

-Certain subjects can more researched, subjects such as use by country, alternatives and fiction are to be severe lacking in sources and other information. Providing more diverse information (example for use by country; ) and spreading into other domains (example for alternatives; Biofuel)

In the subject fiction, Petrofiction can be more defined with added sources or images of renown novels or work from such genre. Novels such as Oil on Water and Rabbit Is Rich.

Alternatives are severely lacking, due to the impact of climate change and the accelerate progress of technology many articles can be found to further add information within the subject. Such as; Biofuel, Aviation fuel, Ethanol and ...

It is a well-done article, however more adding in informations and a regornisation in certain subjects would be most appreciated.

Thanks for that analysis. 'others say that fossil fuels increased whaling' was already cited but I have added a quote within the cite to make it completely clear Chidgk1 ( talk) 11:34, 29 January 2024 (UTC) reply

Re updating Price of oil perhaps you already know that you can download any OWID graph and upload it to Wikimedia Commons for use here on Wikipedia - for example https://ourworldindata.org/grapher/crude-oil-prices Hope you all enjoy your course Chidgk1 ( talk) 11:42, 29 January 2024 (UTC) reply

Thank you for your suggestion and advice. Ghostpants321 ( talk) 02:23, 10 February 2024 (UTC) reply

Why is it not mentioned Samuel Kier? "The world's first oil refinery was built in 1856 by Ignacy Łukasiewicz. " is completely wrong. Kier built the first industrial refinery in 1853. It may not be big but he had the first petroleum distillery at least 3 years before.

Is this something political that Wikipedia gets into? "Let's not give credit to US" kind of thing?

Stop this. It is not what Wikipedia was established to do. 73.223.0.150 ( talk) 23:24, 24 March 2024 (UTC) reply

Distillation has been known for centuries, it is correct. Rose water and alcohol were achieved by the distillation processes. However, there is no indication that crude "oil" was distilled before Samuel Kier in the industrial process. Boiling is not a separation by distillation. 73.223.0.150 ( talk) 23:31, 24 March 2024 (UTC) reply

I'd like to draw attention to the editor ItsCheck, who is repeatedly reverting good-faith edits in an attempt to maintain the inclusion of two irrelevant and politically-motivated sentences at the end of the lead. Arkadios 200 ( talk) 07:19, 26 March 2024 (UTC) reply

Hello, I have removed this politically motivated content and am working on neutralizing the lead section of the article. There is nothing to worry about here. ItsCheck ( talk) 14:04, 26 March 2024 (UTC) reply

@ Arkadios 200 and ItsCheck: ItsCheck has a point but needs some references. The benefits of petroleum are overwhelming and should be recognized prominently. We wouldn't be sitting here typing away without it. -- Smokefoot ( talk) 14:11, 26 March 2024 (UTC) reply

The effects of petroleum on society are less relevant than the properties of petroleum itself in an article about the properties of petroleum, and the lead should reflect that. There are other sections of this article, as well as entire other articles, for discussing petroleum's effects on society. Arkadios 200 ( talk) 17:22, 26 March 2024 (UTC) reply

@ Arkadios 200:. Quoting from the opening section "Petroleum exploitation can be damaging to the environment and human health...."-- Smokefoot ( talk) 18:25, 26 March 2024 (UTC) reply

I don't see how that's either irrelevant or politically-motivated. Arkadios 200 ( talk) 22:44, 26 March 2024 (UTC) reply

This is not an article about the effects of petroleum, this is an article about petroleum, evident by the title. ItsCheck ( talk) 23:28, 26 March 2024 (UTC) reply

Then why are you reverting my edits? Arkadios 200 ( talk) 01:10, 27 March 2024 (UTC) reply

In case it was not clear, the statements you have been removing from the article in the past two days are true. Previously they were not completely correct, but I removed the politically motivated part so there is nothing to worry about. I am sorry if this was not obvious. ItsCheck ( talk) 23:17, 27 March 2024 (UTC) reply

If they're both true and relevant, feel free to find sources for them. Arkadios 200 ( talk) 01:37, 28 March 2024 (UTC) reply

@ Arkadios 200 I am working on adding sources to both of them. ItsCheck ( talk) 22:47, 31 March 2024 (UTC) reply

At this edit, Editor ItsCheck reverted my edit with the edit summary Citation url is indeed dead, not alive.

In cs1|2 templates ({{ cite journal}} in this case), the presence of a url assigned to |archive-url= causes the template to assume that the url assigned to |url= is dead. See these simple examples; this is the default:

{{cite book |title=Title |url=https://www.example.com |archive-url=https://www.archive.org |archive-date=2024-04-02}}

Title. Archived from the original on 2024-04-02.

Adding |url-status=dead to the above example does absolutely nothing except to add extraneous clutter to an article's wikitext; the rendering of the citation is exactly the same as the default:

{{cite book |title=Title |url=https://www.example.com |archive-url=https://www.archive.org |archive-date=2024-04-02 |url-status=dead}}

Title. Archived from the original on 2024-04-02.

As I write this, the live version (permalink) of the article has 76 instances of |archive-url=. Fifty-six of those are marked with |url-status=live. Adding |url-status=live to the above example, does cause the citation to render differently from the default:

{{cite book |title=Title |url=https://www.example.com |archive-url=https://www.archive.org |archive-date=2024-04-02 |url-status=live}}

Title. Archived from the original on 2024-04-02.

My edit should be restored for the reasons just described but more importantly because the revert rebroke this citation.

Sorry about that, I will kindly self revert. ItsCheck ( talk) 00:03, 3 April 2024 (UTC) reply

Thank you.
