You can research the blueprint in the Academy when you've reached 1250 Geniuses (and so it's only available in the Deep Ocean expansion). Vadim Sokow has his own type of Oil Driller, the Oil Driller Sokow Transnational, which is three times as productive. It costs you 9 points every 3 buildings, so increasing oil production can place heavy strains on the ecosystem. Note that sometimes you have spare space where no other building fits so you can build more oil drillers there.ĭon't forget about the problems with Ecobalance caused by oil drillers. It also is not susceptible to fires or oil spills. It is the only building able to produce Crude Oil on land, however it has only a third of the output of an Oil Rig. These are optimally used in a 3:1 ratio between Oil Drillers and Oil Refineries.
The Oil Driller can be used to produce Crude Oil on islands which have the resource available.
