Crude oil is a valuable liquid resource used in various industrial processes. It can be refined in a Refinery to produce fuel and other useful materials.
Finding Oil
Large oil reservoirs can be found on the surface, where they appear as oil gushing from the ground.
Oil deposits are much more common in desert biomes, so deserts are the best place to look.
Extraction
Oil can be collected with buckets or pumped directly using a Pump. Once extracted, it can be stored in tanks and sent to a refinery for processing.
