petroleum
Let an agent explain petroleum and its origin, relay extraction, refining, trade and environmental impacts from geological, industry and policy sources with attribution, describe conventional and unconventional oil and national production, and distinguish petroleum from natural gas, refined products and other oils, presenting geopolitical topics neutrally.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain petroleum and its origin, relay extraction, refining, trade and environmental impacts from geological, industry and policy sources with attribution, describe conventional and unconventional oil and national production, and distinguish petroleum from natural gas, refined products and other oils, presenting geopolitical topics neutrally.
A naturally occurring liquid mixture of hydrocarbons found in geological formations, formed from buried organic matter over millions of years, extracted by drilling and refined into fuels and petrochemicals, including conventional crude, viscous and heavy oils and unconventional oil from oil sands and shale; petroleum is the world s largest traded commodity, with major producers such as Saudi Arabia and Algeria, and its use is central to climate policy debates.
What it is for: Fuel and chemical feedstock.
It can be explain origin and composition; relay extraction, refining and trade; describe kinds and producers; distinguish related substances.
Distinguishing features
Fossil origin
Hydrocarbon mixture
Global commodity
Climate significance
What it looks like
A dark, viscous liquid ranging from light and thin to heavy and tar-like.
Physical character
world production: about 100 million barrels per day - 2020s
API gravity: about 10-50 degrees - heavy to light
first modern well: 1859 year - Titusville, Pennsylvania
How it is recognised
Naturally occurring hydrocarbon liquid
Conventional crude, viscous petroleum, unconventional oil, petroleum in Saudi Arabia and Algeria
Natural gas is gaseous; refined products are made from crude; vegetable oils are unrelated

What the second pass must settle
- Should unconventional oil and national petroleum industries be separate primary entries?
- How should geological and policy sources be linked?
- The registry entry has merged aliases naming an origin theory and national industries; should they be split off?
