Current planner baseline treats Crude Oil as an extracted fluid and oil-field resource rather than a crafted fluid. Public search results and community posts often mix the names Crude Oil, Oil Extractor, and Powerium, so use this page as a route-planning baseline and cross-check your save before you build the full outpost.

Rare isotope gas crucial for fusion reactions, advanced cooling systems, and high-tech component fabrication. Requires specialized extractors in specific map regions.
Industrial chemical for higher-pressure production chains. Crafted in the Refinery from Sulfur Ore and Chemicals, then routed into Supermagnets, Batteries, Turbines, Pumps, and other late Selenian lines. Strategy: sulfur supply and Refinery access are usually the real bottlenecks, so plan a dedicated sulfur mining outpost before scaling acid-heavy builds.
