The quickest Oil farms in ARK: Genesis Ascended Part 1 are in the Ocean biome, especially around oil-node clusters at 89 / 15.4, 90.9 / 13.1, 81.4 / 23.1, 17 / 21.6, 18.7 / 21.1, and 49.5 / 61.2.
Oil on Genesis Part 1 lives almost entirely underwater, so the Ocean biome is where every run starts. You are hunting two things: the standard black Oil Rock nodes that sit in the water and on the sea floor, and a batch of odd-looking harvestable rocks tucked inside a couple of islands that pay out oil when you mine them. Line up the coordinates below and you can farm a full stack without ever touching the Volcanic biome.
Fastest Ocean biome Oil coordinates
| Coordinates | What to farm | Location cue |
|---|---|---|
| 89 / 15.4 | Oil node | Island water |
| 90.9 / 13.1 | Oil nodes | Waterfall cliff |
| 81.4 / 23.1 | Oil nodes | Island floor |
| 17 / 21.6 | Unusual oil rocks | Inner island rocks |
| 18.7 / 21.1 | Oil rocks | Underwater nodes |
| 49.5 / 61.2 | Oil rocks and nodes | Large island waters |
KEY!
The fast answer is to teleport into the Ocean biome and work a chain of small islands, harvesting black Oil Rocks in the shallows and on the sea floor. Two of these islands also hide unusual rocks in their interiors that give oil instead of the flint and stone you would expect — they look different from normal nodes, so mine anything that stands out once you are inside those coordinates. Additional standard Oil Rocks sit under Ornical Island around 38.7 / 27.9 if you want an extra stop.
How to farm Oil in the Ocean biome in ARK: Genesis Ascended Part 1
This run chains the Ocean biome’s richest oil spots into a single loop, starting in the north-western shallows and finishing at the huge southern island.
- Farm the first island’s water node — Drop into the shallows at 89 / 15.4 and harvest the black oil node sitting just off the island.
- Sweep the surrounding water — Circle the same stretch of water — more nodes are scattered on both sides of the island.
- Follow the waterfall cliff — Swim to the far end of the island at 90.9 / 13.1, find the obsidian by the waterfall, and follow it to five or so oil nodes running up the cliff.
- Check the next island’s floor — Move to 81.4 / 23.1 and scan the floor for more oil nodes as you explore the area.
- Mine the unusual inner-island rocks — Swim into the middle of the island at 17 / 21.6 and hit the odd-looking rocks packed inside with a pickaxe for oil.
- Harvest the underwater oil rocks — Swim back out and farm the standard ocean Oil Rocks right below, where eight or more nodes cluster together around 18.7 / 21.1.
- Finish at the large island — Jump into the water at 49.5 / 61.2 for both the unusual oil rocks and normal nodes scattered around one of the map’s biggest islands.
Tools and mounts for faster Oil runs
Bring a pickaxe rather than a hatchet — the pick pulls more oil per node, and a Metal Pick raises your yield further. A gathering dino swings that even higher if you have one that can work underwater.
Because most of these spots are in open water, gear up for the swim. A water-safe mount or a set that keeps you mobile makes a real difference when Ocean biome threats close in mid-harvest, so plan the route around getting in, farming, and getting out rather than lingering.
Oil Rocks versus Oil Veins
Everything in this guide is about Oil Rocks — the harvestable nodes you mine directly with a pick for an instant oil drop. That is the fast, active route, and it is entirely in the Ocean biome.
Oil Veins are a completely separate system. They sit in the Volcanic biome and produce oil passively over time, but only once you place an Oil Pump on top of them — a vein you walk up to and swing at gives you nothing. Legacy Genesis vein coordinates such as 14.7 / 66.2, 13.8 / 67.8, and 27.5 / 81.3 carry over from the original game and are likely to match here, but treat them as probable rather than nailed-down for Ascended. If you want a steady trickle of oil without repeat trips, veins plus a pump are the play; if you want a stack right now, stick with the Ocean rocks above.
Other ways to stock up on Oil
Once the location route is covered, ARK has a handful of broader oil sources worth keeping in your back pocket. Harvesting a Basilosaurus returns a large amount of oil, though the exact haul swings widely with server rates, so aim it as a supplement rather than a fixed number. A Dung Beetle fed poop will produce oil alongside fertilizer, and Tek creatures drop oil together with Electronics and Metal when harvested.
Whatever route you take, the oil feeds the same crafting need: drop Oil and Hide into a forge to make Gasoline, which powers most of your mid-game machines.
Route dangers and spots that may not pay out
The Ocean biome waters are genuinely dangerous, so keep your mount and an escape line close while you farm. Two of the unusual-rock spots — the interior at 17 / 21.6 and the large island at 49.5 / 61.2 — reliably give oil, but similar rocks on at least one other island returned only flint and stone, so if a batch is not dropping oil, move on rather than grinding it. And while the legacy Volcanic Oil Vein coordinates almost certainly still apply, they are worth double-checking on your own before you commit to a pump base around them.
Frequently Asked Questions
Where do I get Oil the fastest in Genesis Ascended Part 1?
The Ocean biome. Work the island clusters at 89 / 15.4, 90.9 / 13.1, 81.4 / 23.1, 18.7 / 21.1, and the big island at 49.5 / 61.2, harvesting the black Oil Rocks in and around the water.
Is Oil in the Ocean biome or the Volcanic biome?
Both, but differently. Harvestable Oil Rocks you mine directly are in the Ocean biome. The Volcanic biome has Oil Veins, which only produce oil passively once you place an Oil Pump on them.
Do the unusual island rocks really give Oil?
Yes — the odd-looking rocks inside the islands at 17 / 21.6 and 49.5 / 61.2 hand over oil when you mine them. Just note that visually similar rocks elsewhere on the map have given only flint and stone, so it is worth a test swing before you rely on a new spot.
What is the best tool for harvesting Oil nodes?
A pickaxe over a hatchet, and a Metal Pick over a basic one. A gathering dino that can operate underwater pushes your per-node yield higher still.
Do Oil Veins need an Oil Pump?
Yes. An Oil Vein produces nothing on its own — you place an Oil Pump on top of it, and it generates oil passively over time. That is separate from the Oil Rocks you mine by hand.
Run a Metal Pick and hit the 18.7 / 21.1 and 49.5 / 61.2 clusters first — they hold the densest oil nodes on the map, so you fill a stack in one dive.
