[[File:Kor.jpg|400px|framed|right|Figure 1. A natural petroleum spring. Although it can be drilled for, natural pools of petroleum can form like this.&amp;lt;ref&amp;gt;Wikimedia Commons. (May 25, 2015). &amp;#039;&amp;#039;Natural petroleum spring in Slovakia.&amp;#039;&amp;#039; [Online]. Available: http://en.wikipedia.org/wiki/Petroleum#/media/File:Kor%C5%88ansk%C3%BD_ropn%C3%BD_prame%C5%88.JPG&amp;lt;/ref&amp;gt;]]&lt;br /&gt;
&amp;lt;onlyinclude&amp;gt;&amp;#039;&amp;#039;&amp;#039;Petroleum&amp;#039;&amp;#039;&amp;#039; is a broad term that groups together a combination of organic [[liquid]]s and [[gas|gases]] that is formed after [[kerogen]] is heated and compressed over long periods of time. This mix can be fairly complex, but the main [[gas]]eous component of petroleum is [[natural gas]] - largely [[methane]] - whereas the main [[liquid]] component is [[crude oil]].&amp;lt;/onlyinclude&amp;gt; Crude oil itself is a complex mixture of hydrocarbons, so the exact composition of petroleum is never the same.&amp;lt;ref name=&amp;quot;wolfson&amp;quot;&amp;gt;R. Wolfson. (May 25, 2015) &amp;#039;&amp;#039;Energy, Environment and Climate&amp;#039;&amp;#039;, 2nd ed. New York, U.S.A.: Norton, 2012, pp. 96-97&amp;lt;/ref&amp;gt; [[Secondary fuel]]s such as [[gasoline]], [[kerosene]], [[heating oil]], and diesel fuel are all included in the definition of &amp;quot;petroleum&amp;quot;.&amp;lt;ref name=&amp;quot;eande&amp;quot;&amp;gt;J. Kraushaar, R. Ristinen. (May 25, 2015). &amp;#039;&amp;#039;Energy and the Environment&amp;#039;&amp;#039;, 2nd ed. Hoboken, NJ, U.S.A.: John Wiley &amp;amp; Sons, 2006, pp. 32&amp;lt;/ref&amp;gt; Petroleum traps [[energy]], first originating from the Sun, that was captured by [[photosynthesis|photosynthetic]] plankton in ancient oceans. Just like [[coal]], petroleum is a type of [[fossil fuel]].&lt;br /&gt;
&lt;br /&gt;
==Formation==&lt;br /&gt;
The formation of petroleum occurred hundreds of millions of years ago during a period known as the Carboniferous period. During this time period, dead organic material accumulated and was decomposed by bacteria. Sediment - mostly mud and sand - then covered this material, creating high temperature and pressure conditions resulting in the creation of [[hydrocarbon]] [[molecule]]s. The resulting materials were either liquid, gaseous, or solid.&amp;lt;ref name=&amp;quot;eande&amp;quot;/&amp;gt; For more specific explanations of the formation of different components of petroleum, see the [[oil formation|formation of oil]] or the [[natural gas formation|formation of natural gas]]. Petroleum exists in many [[sedimentary rock]] formations, and because of its [[fluid]] nature it is able to migrate through stone and collect in porous rocks.&amp;lt;ref name=&amp;quot;E2&amp;quot;&amp;gt;G. Aubrecht. (May 25, 2015). &amp;#039;&amp;#039;Energy: Physical, Environmental, and Social Impact&amp;#039;&amp;#039;, 3rd ed. San Francisco, CA, U.S.A.: Pearson, 2006, pp. 217&amp;lt;/ref&amp;gt; If this petroleum within the [[porosity|porous]], [[permeability|permeable]] sedimentary rock is contained here by a layer of impermeable rock then a [[oil and gas trap|trap]] is formed. The movement of geological structures and force of gravity cause these accumulations - called reservoirs - to lie beneath land or oceans.&amp;lt;ref name=&amp;quot;eande&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Recovery==&lt;br /&gt;
Although petroleum seeps do exist, such as the one in Figure 1, they are rare. Most petroleum is collected through oil drilling. Once the petroleum has been drilled for by the [[oil derrick]], a [[pump jack]] is used to recover the fuel. Once it has been recovered, petroleum must be separated into its different components for use. The main method of separation and refinement of petroleum is [[fractional distillation]].&amp;lt;ref&amp;gt;Pepco. (May 25, 2015). &amp;#039;&amp;#039;How is crude oil separated into different petroleum products?&amp;#039;&amp;#039; [Online]. Available: http://www.pepco.ca/blog/index.php/2011/09/25/how-is-crude-oil-separated-into-different-petroleum-products/?lang=en&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Products==&lt;br /&gt;
The separation of petroleum yields many useful products. These products are useful for transportation, fuel oil for heating and electricity generation, and asphalt. Products include [[gasoline]], jet fuel (or [[kerosene]]), [[propane]], petroleum [[coke]], [[bitumen]], plastics and waxes.&amp;lt;ref&amp;gt;EIA. (May 25, 2015). &amp;#039;&amp;#039;What are the products and uses of petroleum?&amp;#039;&amp;#039; [Online]. Available: http://www.eia.gov/tools/faqs/faq.cfm?id=41&amp;amp;t=6&amp;lt;/ref&amp;gt;&lt;br /&gt;
