Crude Oil is not mined — you place a Crude Oil Extractor on an oil field, or use the High-Pressure version which needs no field at all. The three Rayne Syndicate oil rigs are raid targets worth clearing for their golden chests, not for the oil.
Oil = Extractor at Tech 50 on an oil field, or High-Pressure Extractor at Tech 51 anywhere. Rigs are at roughly (160–169, -280 to -297), (579–580, -423 to -430) and (-1722 to -1730, -1450 to -1462). Crude Oil makes Plasteel, not Polymer.

Where oil fields are
Oil ponds are confirmed in Mount Obsidian and the Astral Mountains on the Palpagos Islands, and Feybreak carries a large share of the game's nodes. Community map data counts 185 Crude Oil markers across all regions — for comparison, the same dataset counts 1,463 Ore and 520 Coal, so oil fields are genuinely scarce.
One database links a map filter but carries no node list, and the other has no oil field location table. Widely circulated per-region node counts (Feybreak 63, Twilight Dunes 31, Outlying Isles 30) come from community write-ups and are unverified. This guide names regions instead of inventing coordinates.
The extractors
| Structure | Tech Lv | Materials | Power/sec | Needs an oil field? |
|---|---|---|---|---|
| Crude Oil Extractor | 50 | See note below | 2,000 | Yes |
| High-Pressure Crude Oil Extractor | 51 | 300 Pal Metal Ingot, 50 Circuit Board, 50 Bio Battery, 10 Ancient Civilization Parts | 3,000 | No |
One set of figures gives 125 Pal Metal Ingot and 25 Circuit Board. Another gives 250 Pal Metal Ingot and 50 Circuit Board — exactly double. Budget for the higher figure and you cannot be caught short.
The High-Pressure Extractor is the one that changes your base planning: because it works anywhere, you stop being forced to build on a scarce oil field. It costs 1,000 more power per second and 10 Ancient Civilization Parts, which is a fair trade for placing your oil production next to your Circuit Board line instead of across the map.
Output is 1 Crude Oil per 8,000 workload on the standard Extractor. The work suitability required to operate them is not stated on either database — both show an empty Pal labour section — so that detail is unverified.
The three oil rigs
| Rig | Where | Coordinates | Level | Region |
|---|---|---|---|---|
| Barge Oil Rig / Rayne Syndicate Test Drilling Rig | Lake north of the Sealed Realm of the Frozen Wings | (160, -280) or (169, -297) — open on map | 25–30 | Palpagos Islands |
| Rayne Syndicate Oil Rig | Southeast of Marsh Island | (580, -430) or (579, -423) — open on map | 55 | Palpagos Islands |
| Rayne Syndicate Platform Oil Rig | West of the Feybreak Shipwreck | (-1730, -1450) or (-1722, -1462) — open on map | 60 | Feybreak |
Community references print one set of coordinates and our own map extraction prints another, differing by 8–17 units on each axis — close enough that both land you on the same structure. Names also differ between sources: those references use "Barge Oil Rig", "Oil Rig" and "Platform Oil Rig", while the extracted data uses the Rayne Syndicate naming. They also list the lowest rig at level 25, where the extraction says level 30.
What defends each rig
| Rig | Defences | Added in |
|---|---|---|
| Barge (Lv25–30) | Gun turrets | v0.4.11.0 (Feybreak) |
| Oil Rig (Lv55) | Laser turrets, gun turrets, elite units including the Syndicate Crusher | v0.3.1.0 (Sakurajima era) |
| Platform (Lv60) | Laser turrets, rocket platforms, a Rayne Syndicate helicopter | v0.4.11.0 (Feybreak) |
Version 1.0 improved oil rig treasure chest rewards with additional obtainable items, so pre-1.0 loot lists undercount what is in there now.
Oil rig loot
Every rig has ordinary chests scattered around it plus a single golden chest that spawns in one of several possible locations. The golden chest is the reason to go.
Golden chest highlights
| Rig | Standout drops |
|---|---|
| Barge (Lv25–30) | Crude Oil 5–15 at 100%; Gold Coin 1,000–2,500 at 32%; crossbow, musket and arrow schematics 1–12%; 39 skill fruits at 2.56% each |
| Oil Rig (Lv55) | Ancient Civilization Core 1–5 at 93%; Crude Oil 50–150; Training Manual (L) and (XL) 3–5 at 100%; five Lotus variants at 20% each |
| Platform (Lv60) | Ancient Civilization Core 1–5 at 90%; Crude Oil 150–300 at 100%; Bow, Laser Gatling Gun, Missile Launcher and Plasma Cannon schematics Lv2–4 at 1.25–14.75% |
Ordinary chest highlights
| Rig | Notable | Rate |
|---|---|---|
| Barge | Giga Sphere ×2–5 | 53.6% |
| Barge | High Grade Technical Manual | 3.2% |
| Barge | Ancient Technical Manual | 2.2% |
| Oil Rig | Large Pal Soul | 27.9% |
| Oil Rig | Gold Key | 13.9% |
| Platform | Giant Pal Soul | 31.1% |
| Platform | Gold Key | 15.6% |
| Platform | Hexolite armour and helmet schematics | 0.01–3.9% |
Every rig's second chest slot also pays Dog Coins at a flat 25% — 5–10 on the Barge, 15–20 on the Lv55 rig and 16–20 on the Platform.
A Lv55 or Lv60 golden chest is one of the best Ancient Civilization Core sources outside a raid boss, at 90%+ for 1–5. If what you actually need is Crude Oil, the High-Pressure Extractor produces more with no combat.
Pals and enemies that drop Crude Oil
What Crude Oil is used for
| Product | Recipe (source A) | Recipe (source B) |
|---|---|---|
| Plasteel | 2 Crude Oil + 5 Ore | 5 Crude Oil + 10 Ore + 5 Paldium Fragment |
| Flamethrower Fuel | 2 Crude Oil + 1 Refined Ingot | 1 Crude Oil → 5 fuel |
| Frag Grenade Mk2 | Listed | 3 Crude Oil + 1 Gunpowder + 3 Pal Metal Ingot |
| Missile Ammo | 3 Pal Metal Ingot + 1 Crude Oil + 1 Computer | Not listed |
| Wing Cell, accessories | Listed | Not listed |
The two sources disagree on nearly every quantity, so plan against the larger figure. Plasteel is the important one — it feeds the Plasma Multicutter and the Metal Detector, which in turn gate Sunreach and Feybreak resource gathering.
Polymer does not appear as a Crude Oil product on either database. Polymer comes from High Quality Pal Oil. Guides that route Crude Oil into Circuit Boards have the chain wrong.
What to do next
- Rush the High-Pressure Extractor at Tech 51 if oil field placement is cramping your base.
- Clear the Lv55 rig for Ancient Civilization Cores once you can handle laser turrets.
- Bank the Dog Coins the rigs drop — every chest slot 2 pays them at 25%.
