Pumpjack

Overview
The pumpjack is a fluid-extraction building whose output can still be improved even after a resource field has depleted to its minimum yield of 20%. Because of this, speed modules remain useful on low-yield fields and are a strong way to raise the building’s output instead of replacing it.
With two speed module 3s installed directly in the pumpjack, the output doubles from 2 to 4 fluid per second on a depleted field. With two legendary speed module 3s, the output rises by a factor of 3.5, from 2 to 7 fluid per second. This makes module choice especially important when a field is nearly exhausted.
The modified output can be calculated with the following formula:
Output of unmodified pumpjack × (1 + number of modules in pumpjack × average module bonus + transmission strength × number of modules in each beacon × average module bonus)
For a pumpjack on a depleted resource field with two level 3 speed modules and four beacons, each containing two level 3 speed modules, the calculation is:
2 × (1 + 2 × 0.5 + √4 × 1.5 × 2 × 0.5) = 10 fluid per second
If the setup is assumed to always use two speed 3 modules in the pumpjack and in the beacons, the expression for four beacons can be shortened to:
2 × (2 + √4 × 1.5) = 10 fluid per second
- Speed modules remain effective on depleted fields, so they are a practical upgrade even when the resource patch is at its minimum yield.
- Beacon support scales strongly with the pumpjack, and the example shows that beaconed speed modules can raise output far beyond the base value.
- The formula depends on the average bonus of the modules used, so higher-tier and legendary modules have a much larger effect than standard ones.
