Holding a seep
Set up a pumpjack, maintain a wellhead and take over another team's tap.
In short
- Control individual taps with wellheads; the seep itself cannot be owned.
- A lubricated seal resists breaking. Use a Cutting Torch to take the tap.
- In a week a seep gives at most its weekly cap.
How to find and sell oil is on Oil.
Pressure
- Pressure rises until the reserve is full
- Oil extracted this week
- Weekly extraction limit
- A new week resets the extracted amount, not stored pressure
- The Heart breathes: more flow, the same cap
- A raider can take the current reserve
Pressure accumulates until the seep's reserve is full. Extraction uses that reserve and counts towards the weekly limit. A new week resets the extracted amount without clearing stored pressure. Use an oil scanner to check the current pressure.
Pumpjack count, rotation speed and arm length affect extraction. Each pumpjack is limited to its seep block's share. To collect the whole seep's flow, place a pumpjack on every seep block.
Taps
Each seep block supplies one tap and has its own share of the weekly extraction limit. Replace the Casing Stub above it with a Wellhead, then place the pumpjack's hole on the Wellhead. Only the team controlling the Wellhead can install that hole and extract oil through it.
- Pumpjack Hole
- Wellhead
- Fluid Pipe
- Oil Seep
A new Wellhead's seal lasts for a limited time. Maintain it with 
Lubricant made from naphtha and bitumen in a heated mixer; JEI shows the recipe. Fill a 
Grease Gun at a spout, or from a tank while sneaking, then use it on the Wellhead.
- Cutting is abandoned or times out, or another team lubricates the seal: Progress can be lost; only fuel already used is spent
- The cut finishes: The tap passes to the cutter's side
- The seal runs out of lubricant:
- The seal goes slack
- anyone can break the Wellhead
A lubricated seal prevents the Wellhead itself from being broken, blown up or moved. Another team can take it by using a 
Cutting Torch. The holding team can interrupt cutting by adding lubricant. Once the seal expires, anyone can break and collect the Wellhead.
Every seep except the Heart's has one wild throat: a public tap that cannot take a Wellhead and lets anyone extract a small share of the weekly limit.
Build a sealed room around the taps, add a scrubber and bed, and keep spare parts nearby. You will need to return to maintain the wellheads.
Anyone can break pumps, pipes and walls in the Dark Zone. The automatic land log does not record those actions; place your own Garrison Logbook beside the Wellhead to record supported local events. Killing still follows the usual rules: killing an outlaw or in valid self-defence does not start a hunt for the killer.
Weekly event and long-term changes
The Heart's weekly event increases seep flow for a few hours without increasing the weekly extraction limit. The event day is announced at the start of the week; its exact time is hidden. Each new season redistributes a layer's flow and extraction limit between its seeps.
Extracting a seep's full weekly allowance repeatedly attracts more undead while players are nearby, eventually including a warlord. Weeks with less extraction reduce that activity.
Fill the Cutting Torch under a spout or by clicking a gasoline tank. Its bar shows fuel; cutting progress appears above the hotbar. Fuel is spent only while cutting. An interruption can lose progress, but does not consume the unused fuel.
