Oil Rig

Information

 * The oil rig is the base structure used for the production of Oil.
 * Oil is the most common resources, and therefore the least valuable.
 * Oil is used most prominently in the research and construction of hulls and the upgrading of buildings, but is also used in every other build of a ship or building or weapon for your base.
 * Oil is quickly produced by Oil Rigs at your base and by oil wells which can be commonly found at any level on the Map.
 * Oil wells on the map can no longer be captured (2014)
