Resource Wells in Satisfactory: How They Work
One pressuriser activates a cluster of satellite nodes. Why overclocking the pressuriser is unusual, and why wells skew heavily toward pure nodes.
Resource Wells work differently from every other extraction point in the game, and the difference is worth understanding before you build one: you overclock the pressuriser, not the extractors.
The structure
A well is a cluster, not a node. One core where the Resource Well Pressurizer goes, plus satellite nodes scattered around it that each take a Resource Well Extractor.
The pressuriser activates the whole cluster. Without it the satellites do nothing; with it, every extractor on that well can run.
There are 17 cores and 118 satellites in the world:
| Resource | Cores |
|---|---|
| Water | 8 |
| Nitrogen Gas | 6 |
| Crude Oil | 3 |
Nitrogen Gas has no ordinary resource nodes at all — those six well cores, with 45 satellites between them, are its only extraction points in the world.
There is one alternative, and it arrives very late: the Converter can produce Nitrogen Gas from Bauxite or from Caterium. That is a genuine second source, but it needs the Converter itself plus Reanimated SAM, so for most of a playthrough the wells are the supply.
Satellite rates by purity
| Purity | At 100% | At 250% |
|---|---|---|
| Impure | 30 m³/min | 75 |
| Normal | 60 m³/min | 150 |
| Pure | 120 m³/min | 300 |
Now the part that makes wells attractive. Across all 118 satellites:
| Purity | Count |
|---|---|
| Pure | 76 |
| Normal | 25 |
| Impure | 17 |
Wells skew heavily toward pure, which is the reverse of ordinary resource nodes. Nearly two thirds of satellites are pure, so a typical well is far more productive than its satellite count alone suggests.
Overclocking the pressuriser, not the extractors
This is the mechanic that catches people.
Overclocking the Pressurizer raises the whole well’s output, and it affects every satellite equally. Push it to 200% and every extractor on that well produces twice as much.
You do not overclock the extractors individually. The pressuriser is the control point for the entire cluster.
The practical consequence: a well is an unusually good place to spend Power Shards. One overclocked building multiplies output across up to a dozen extraction points at once, where the same shards on ordinary miners would each affect one node.
The Pressurizer draws 150 MW at 100%, and it is a production building rather than a generator, so power scales by the exponent — 250% costs about 3.36 times that. Budget for it.
When a well is worth building
Nitrogen Gas: effectively always. There are no ordinary nitrogen nodes, and the Converter route arrives too late to help with the chains that first need it.
Water: usually not. Ordinary Water Extractors give 120 m³/min for 20 MW and can go in any deep water. A water well needs a 150 MW pressuriser plus extractors. Wells make sense for water only when you need a very large supply in one place and there is no lake nearby.
Crude Oil: depends on your oil situation. Three cores exist. If your ordinary oil nodes are far from where you need the crude, a well can be closer.
Building one
The order matters and the mistakes are avoidable.
Find the core first. Satellites without a pressurised core produce nothing, and the core is not always the most obvious node in the cluster. The Resource Scanner helps.
Power the pressuriser before placing extractors, so you can see the well activate.
Plan the pipe routing before building extractors. Satellites are scattered, sometimes across awkward terrain, and a well producing 600 m³/min across several extractors needs serious pipe capacity — Pipeline Mk.2 carries 600 m³/min, so a large well is a multiple-pipe problem from the start.
Check head lift on the routing. Satellites at different heights around a core is the normal case, and fluids do not climb for free.
The throughput trap
A fully pure well with many satellites, overclocked, produces more fluid than you can move on a single pipe.
Six pure satellites at 250% is 1,800 m³/min — three full Mk.2 pipes, and you should not plan any pipe at its stated ceiling because sloshing means real throughput sits below it.
Size the pipes before overclocking the pressuriser, or you will spend shards on output that backs up at the extractor.
Nitrogen Gas deserves its own note
Six cores and 45 satellites, and no ordinary resource nodes anywhere. That makes nitrogen one of the most structurally constrained resources in the game.
What needs it: Nitric Acid, which feeds Rocket Fuel and the quartz purification route; Cooling Systems; and several late-game frames. None of those are optional if you intend to finish.
Two practical consequences:
Secure a nitrogen well before you need it. The chains that consume nitrogen arrive together, and building the well under time pressure while a phase waits is unpleasant.
Overclock the pressuriser rather than hunting for a second well. With only six cores in the world, and the satellites skewing pure, raising output at a well you already have is usually easier than establishing another site.
The Converter route is a late-game supplement, not a plan. Producing nitrogen from bauxite or caterium works, but it consumes resources that have their own demands and it unlocks well after you first need nitrogen.
Comparing a well against ordinary nodes
Worth putting side by side, because the arithmetic is not obvious.
An ordinary oil node at normal purity gives 120 m³/min from an Oil Extractor at 40 MW. Simple, one building, one pipe.
An oil well with, say, four pure satellites gives 480 m³/min at 100% clock — four times as much — but costs a 150 MW pressuriser plus four extractors, and needs pipe capacity to match.
So a well is not strictly better. It is denser: much more output concentrated in one place, at a higher fixed cost and with more infrastructure. That density is exactly what you want when the alternative is three separate outposts, and exactly what you do not want when one ordinary node would have covered the demand.
Common mistakes
Overclocking the extractors individually. The pressuriser is the control point, and raising it affects every satellite on that well at once.
Building a water well next to a lake. Ordinary extractors are 20 MW and go anywhere deep enough.
Forgetting the pressuriser’s 150 MW. Plus the exponent if you overclock it.
Piping a large well on one line. A pure well at high clock exceeds a Mk.2 pipe comfortably.
Assuming satellites work without the core. They produce nothing at all until the well has been pressurised, no matter how many extractors you place on them.
