Petroleum

Petroleum is found in swampy areas. There is usually a big lake or swamp next to them where you can rarely place a harbour. In many maps, (Pangea for example) these swampy areas are found at the very corners of the landscape.
==History==
In 1556 the German mineralogist Georgius Agricola described how to skim off petroleum at seeping sites and thicken it by heating it in order to gain a material suitable for the waterproofing and caulking of ships. From 1650 on, petroleum was distilled - a procedure which produced car lubricants, varnish and paint bonding agents as well as lamp oil. Towards the end of the 1850s, the petroleum industry came into existence with the introduction of systematic crude-oil drilling. In 1890 the US chemists James Dewar and R. Redwood got their commission for a new procedure of cracking petroleum thermically which, compared to previous methods, brought about a higher yield of heating oil.

Towards the end of the 1850s, the petroleum industry came into being with the introduction of systematic crude oil drilling. In 1890 the US-chemical scientists James Dewar and R. Redwood got their commission for a new method of cracking crude oil thermically. Compared to earlier techniques, this procedure enabled a higher exploitation of resources. The 20th century can be called the 'age of black gold' - the term which economists use for petroleum - as crude oil is essential to modern society.
