Pumpjack

A pumpjack is a mining/production building used on fluid resource fields. Its output from a depleted resource field (which still retains a minimum of 20% of its original yield) can be increased by inserting speed modules into the pumpjack and by supplying module effects through nearby beacons. When a resource field has been depleted to that minimum, speed modules remain an effective way to raise the pumpjack's fluid output.

The modified output of a pumpjack is calculated by taking the output of the unmodified pumpjack and multiplying it by the sum of the direct module bonus and the beacon-delivered module bonus. The effective multiplier equals (1 + number of modules in pumpjack × average module bonus + transmission strength × number of modules in each beacon × average module bonus). Transmission strength is the beacon transmission factor (beacon effect strength); the beacon contribution scales with the square root of the number of beacons affecting the pumpjack when multiple beacons are present in a symmetric arrangement.

Practical examples and typical numbers:

• On a depleted resource field, the unmodified pumpjack base output is 2 fluid per second. Equipping two Speed module 3s in the pumpjack doubles that output to 4 fluid per second.

• With two legendary Speed Module 3s (higher average module bonus), the same base of 2 fluid per second can increase to 7 fluid per second.

• Example calculation for a pumpjack on a depleted field with two Level 3 speed modules in the pumpjack and four beacons each containing two Level 3 speed modules: 2 × (1 + 2 × 0.5 + √4 × 1.5 × 2 × 0.5) = 10 fluid per second. In this example the expression is simplified (assuming two speed-3 modules per beacon) to: 2 × (2 + √4 × 1.5) = 10 fluid per second.

• Bullet notes:

  • Depleted fields retain at least 20% yield; speed modules still increase that yield.
  • The formula uses the unmodified pumpjack output as the base; module and beacon bonuses are multiplicative factors applied to that base.
  • Beacon contributions depend on the beacon transmission strength and the number of modules in each beacon; arrangements of multiple beacons are combined (the example uses √4 to represent two layers of symmetrical beacon coverage).
  • Using higher-tier speed modules and adding beacon coverage yields large multiplicative gains in fluid output, often more effective than other module types for maximizing flow from depleted wells.

These calculations allow precise planning of module and beacon setups to achieve a desired fluid throughput from pumpjacks on depleted resource fields.
