Oil was drilled for the first time at Titusville, Pennsylvania, in 1859. In 1865 the first oil pipeline, six miles long, was constructed. Eventually, oil came to supply much of the world's energy needs.
The discovery that oil drilling could be performed economically permits Drillers to be educated in the university. They will produce Oil at Level I: two units per turn. Additionally, Prospectors may search for Oil in Desert, Tundra and Swamp terrain. It is now possible to construct a Refinery and Power Plant.
