Oil Patch

Oil Patches are concentrated areas of oil found in most water-based maps in Warcraft II: Tides of Darkness and Warcraft II: Beyond the Dark Portal.
An oil platform can be built on top of these areas by both Alliance and Horde that will allow a friendly oil tanker to extract the precious black substance and haul it back to an allied shipyard for resource collection. Oil patches are important resource nodes for building and maintaining a strong navy during the game.
Large pools of this highly flammable substance are found far beneath the surface of the sea. Special platforms must be constructed in order to drill deep enough into the ocean floor to get at this sticky, black substance. Dark oily patches, created by small geysers that form on the ocean floor and spew modest amounts of oil into the surrounding waters, serve as a beacon to oil tankers hunting for the rich black liquid. Although oil is commonly used in the construction and powering of ships, it has been utilized in the development of both experimental flying craft and extremely powerful weapons.Warcraft II: Tides of Darkness manual, Resources of the Land, Oil
