Oil Processing and Energetic Graphite Guide

If your power grid is wobbling, your fuel slots are filling up with the wrong stuff, or your first oil field looks like a confusing mess of byproducts, this is the chain that gets you unstuck. Oil processing and Energetic Graphite are the bridge from early mining to a factory that can feed both power and mid-game production. Start small, keep one eye on your crude output, and make sure every byproduct has a destination before you scale up.

Set up the first oil chain without overbuilding

Your first goal is simple: get Crude Oil out of the ground, turn it into Refined Oil and Hydrogen, and do not let the refinery sit idle because one output has nowhere to go. Crude Oil appears on life-bearing planets, including the starter planet, and it is extracted from Crude Oil Seeps with an Oil Extractor. On the starting planet you typically have around 30/s total spread across the available seeps, which is enough to matter but not enough to waste.

That is why you should begin with only a small extraction and refining setup. Crude Oil is not a permanent tap; each seep gradually declines while it is being extracted, with a default half-life of 12 hours and a minimum production rate of 0.1/s. Build to cover immediate Hydrogen and Refined Oil demand, then expand after you see how the seep actually behaves over time. A strong-looking field can still taper off, so do not overcommit your early factory to a single planet’s oil.

The core first step is Plasma Refining in an Oil Refinery. That gives you Refined Oil and Hydrogen, and it is usually the right opening move because it keeps both early power and chemistry moving. Refined Oil is the more flexible product, while Hydrogen is the one you must manage carefully so the line does not back up.

Here is a quick reference for the core chain and what each piece is good for:

Use coal to get Energetic Graphite flowing early

If you have Coal available, do not leave it sitting in a raw-fuel pile forever. Coal is mined with the Mining Machine, and the best early move is to smelt it into Energetic Graphite in a Smelter. Coal is a good starter fuel, but Energetic Graphite is much better for inventory efficiency and long-term usefulness.

This matters most for Icarus. Coal burns for 1 second per piece and gives you a decent emergency buffer, but Energetic Graphite stacks more densely in terms of energy, so your fuel slots go much further. In practice, you want Coal to become your graphite line, not your long-term hand-burn fuel. If you are still burning raw Coal everywhere, you are making your fuel logistics harder than they need to be.

There is also a solid power reason to do this early. Even after the power needed for smelting and sorters, turning Coal into Energetic Graphite is energy-positive. That means you are not losing power by processing it; you are upgrading your fuel. For Thermal Power Stations, Energetic Graphite burns for 2.5 seconds per unit and consumes 24 per minute, which is a noticeably better fit than Coal’s 60 per minute. If you want your early power grid to feel less hungry, graphite is the cleaner fuel.

A good rule is to dedicate a Coal line to graphite as soon as you have the basics working. A Mining Machine covering two Coal veins can supply enough Coal for one Arc Smelter to produce Energetic Graphite at a steady pace, assuming no Veins Utilization upgrades. That is a very manageable first setup, and it gives you a fuel backbone without demanding a huge build.

Route Hydrogen and Refined Oil so the refinery does not jam

The most common oil mistake is building the refinery before you know where both outputs are going. Do not do that. Plasma Refining produces both Refined Oil and Hydrogen, and if either one backs up, the refinery slows down or stalls. Your job is to give both outputs a clear path before you expand the line.

Hydrogen should be routed immediately into later production or looped back into cracking when you have excess. The key point is that Hydrogen created during crude-oil-based production must be recycled through the system to ensure full efficiency. If you let Hydrogen pile up, you are not just wasting storage space; you are choking the whole chain.

Refined Oil also needs an outlet. Early on, it can go into Storage Tanks or be transported as a fluid to the chemical side of your base. Later it becomes a major input for Plastic and Sulfuric Acid, and it also shows up in other advanced routes. The important habit is to plan storage and consumers before you start scaling refinery count. Build handling first and expansion second.

If Refined Oil starts stacking up while Hydrogen is under control, crack the excess instead of immediately burning it. If Hydrogen is your surplus, use it where it belongs rather than letting the refinery idle. The oil system works best when you treat the two outputs as a pair, not as independent products.

Decide when to burn oil and when to process it further

Directly burning Crude Oil is possible, but it should be your fallback, not your standard plan. Refining Crude Oil first is generally more efficient, and processing it through Plasma Refining gives you a net energy gain if the products are then used as fuel. In other words, crude is usually better as an input to your chain than as something you throw into a Thermal Power Station.

The same logic applies to Refined Oil. You can burn it, but that is usually the least attractive use. Refined Oil burns for 1.66 seconds per unit and consumes 36.0 per minute, so it is a workable emergency fuel, not a preferred sink. If your goal is energy production, process excess Refined Oil through X-Ray Cracking in an Oil Refinery instead of burning it directly. That route is the better way to turn extra oil into useful output.

So the decision rule is straightforward: process first, burn later. Use Crude Oil for refining, use Refined Oil for chemistry or cracking, and only send either one to Thermal Power Stations when you need to clear a backlog or survive a temporary shortage elsewhere.

Scale Oil Processing for research and mid-game materials

Once the first refinery loop is stable, start thinking of oil as a materials hub rather than a power trick. Energetic Graphite is an early ingredient for the Energy Matrix, and it stays useful later as fuel and as a crafting ingredient. Refined Oil becomes even more important because it feeds Plastic and Sulfuric Acid production, and it also appears in some routes for Organic Crystal and other advanced materials.

This is where many factories stall: they keep enough oil for power, but not enough for chemistry. Do not make that mistake. Keep graphite production steady so your Icarus fuel and research do not dry up, but reserve enough Refined Oil for the plastics and acid lines that will define your mid-game. If you run oil only as a power chain, you will end up short on the very materials that unlock the next tier of production.

The good news is that both Coal and Crude Oil remain useful well past the opening hours. Coal still feeds Energetic Graphite, and Crude Oil still anchors your chemical production. If you set up the line carefully, you will get a stable fuel source, reliable research input, and a clean path into Plastic, Sulfuric Acid, and other advanced materials without constantly rebuilding your infrastructure.

The best long-term habit is simple: keep a modest graphite supply running, keep Hydrogen moving, and protect your Refined Oil from waste. If you do that, oil stops being a bottleneck and becomes one of the most reliable bridges in your factory.
