Description
This is the Oil Refinery, and it is used to produce Oil in Anno 1800. To begin with, Oil in Anno 1800, becomes a core resource as you progress further into the game, especially because it sits at the very start of the Electricity production chain.
In addition, the Oil Refinery must be supported by Oil Wells. Oil Wells extract the Oil from the ground and send it directly to the Refinery. Once the Refinery receives the Oil in Anno 1800, it passes it along through the railway network so it can be transported to wherever it is needed.
Overall, the Oil Refinery is the foundation of your power system, making it essential for running advanced buildings and boosting your industrial efficiency.
What is produced
This is Oil in Anno 1800. To start with, it is produced by Oil Wells, which automatically send the Oil to the Oil Refinery.
In addition, Oil is generated at a steady rate of four tons per minute, making it an important resource for powering your Electricity network and advanced production chains.

Improvements
In this section, we will look at how to improve the productivity and efficiency of the Oil Refinery. To start with, the placement of the Refinery depends on where the Oil deposits are located on your island. Keeping it close to its Oil Wells helps reduce travel time and keeps production steady.
In addition, it’s best not to connect more than four Oil Wells to a single Refinery, as going beyond this increases the risk of fires and slows down efficiency.
Next, we can look at how the Trade Union can help. By placing a Trade Union nearby, you can boost the Refinery’s output by adding items to its slots. Any building within the Trade Union’s range will receive the benefits from these items, making your Oil production faster and more reliable.
Placement
In this section, we will look at where to place the Oil Refinery for maximum efficiency. To start with, the Refinery needs to be placed close to Oil Deposits, which appear on islands in every region of the game.
For best results, aim to place the Refinery near four Oil Deposits, as this is the ideal number for safe and steady production. Using more than four increases the risk of fires and slows down efficiency.
Once the Refinery is placed, the next step is adding Oil Wells. You place each Oil Well directly on top of an Oil Deposit, and the Oil will automatically flow from the Wells to the Refinery without any extra setup.
With that done, your Oil production chain is ready to run smoothly. Let’s take a look at this placement now.

As you can see here to Oil Refinery is in the centre of the Oil Wells. The Oil Wells will deliver Oil directly to the Oil Refinery.
Trade Union
Here we will look at which items you can add to the Trade Union to improve the Oil Refinery. To start with, these items can increase both productivity and efficiency, making your Oil production run much more smoothly.
In addition, you can obtain these items from many places around the map. This includes buying them from NPCs, completing quests, going on expeditions, and several other methods of item collection.
With that in mind, let’s take a look at some of these items now.
| Item name | Effects | Rarity/Notes |
|---|---|---|
| Prospector | -50% Maintenance Cost | Common, Expedition Bonus – +10 Crafting |
| Calciner | +40% Productivity, -3 Attractiveness, +50% Chance of Fire | Uncommon, |
| Coal permit | +25% Productivity, +20% Attractiveness | Uncommon, |
| Drill | +25% Productivity, +25% Maintenance Cost | Uncommon, Expedition Bonus – +15 Crafting |
| Night pollution by-law | -10% Productivity, -40% Attractiveness | Uncommon |
| Refiner | +20% Productivity | Uncommon, Expedition Bonus – +20 Crafting |
| Heavy coal permit | +40% Productivity, +40% Attractiveness | Rare |
| Mechanical drill | +35% Productivity, +15% Maintenance Cost | Rare,. Expedition Bonus – +25 Crafting |
| Night and Day Pollution By-Law | -20% Productivity, -60% Attractiveness | Rare |
| Reverberatory Furnace | +50% Productivity, -2 Attractiveness, +30% Chance of fire | Rare |
| Bechamel Converter | +60% Productivity, -1 Attractiveness, -50% Workforce needed | Epic |
| Fine Handheld Power Auger | +40% Productivity, -20% Workforce needed | Epic, Expedition Bonus – +35 Crafting |
| Green’s Law to Postpone The Apocalypse | -30% Productivity, -80% Attractiveness | Epic |
| Lord Footprint’s Gargantuan Smokestack Act | +55% Productivity, +60% Attractiveness | Epic |
These are ten items for the Oil Refinery in Anno 1800.
Layouts
In this section, we will look at the best layouts for the Oil Refinery. To start with, it’s important to place the Refinery so it can cover four Oil Wells, as this is the ideal number for safe and efficient production.
If there are more Oil Deposits in the area, the next step is to place additional Oil Refineries to make sure every deposit is used. This keeps your Oil production steady and prevents bottlenecks later in the game.
With that in mind, let’s take a look at this layout now.
Option 1
In this layout we will be placing down the Oil Refinery along with three Oil Wells

This is a basic layout that produces 12 tons of Oil per minute. To start with, each Oil Well produces one ton of Oil every 15 seconds, which adds up to four tons per minute.
Since this layout uses three Oil Wells, we simply multiply the output by three, giving a total of 12 tons of Oil per minute.
Overall, this makes the layout efficient, easy to build, and perfect for early Oil setups.
Option 2
In this next layout we will be placing down two Oil refineries along with six Oil Wells.

Here we can see the layout described above. This layout will produce 24 tons of Oil per minute.
