Pumpjacks extract crude oil from oil fields. Each oil field can be covered by only one pumpjack at a fixed spot. The pumpjack will then output an amount of crude oil per cycle equal to 10 multiplied by the field's yield (e.g. 54 crude oil for 538% yield) per second. Without speed modules, one pumpjack cycle takes one second to complete.

Extracting oil lowers the field's yield by 1% per 300 pumpjack cycles to a minimum of 20% of the initial yield or 2 oil per second, whichever is larger. They are limited to a maximum output of 1000 crude oil per cycle, achieved by an oil field with more than 9999% yield. However, such a high yield is rare with standard map generator settings.

Pumpjacks cannot be placed on a non-oilfield tile. Furthermore, the output pipe location is fixed relative to the pumpjack's orientation.

Tips

If oil fields are depleted (to the minimum of 20%) speed modules are a good option to raise the pumpjacks output. With two speed module 3's the output doubles from 2 to 4 crude oil per second, plus another 1 oil per beacon per second.

The formula to determine the modified output is:

Output of unmodified oil field * [1 + (number of modules in pumpjack * bonus from module) + (number of beacons * distribution efficiency * (number of modules in each beacon * bonus from module))].

Example
For 1 pumpjack on a depleted oil field with two level 3 speed modules and 6 beacons with each two level 3 speed modules:	2 * [1 + (2 * 0.5) + (6 * 0.5 * (2 * 0.5)) ] = 10 Crude oil per 1 second.
Assuming that there will be always two speed 3 modules equipped in the pumpjack and beacons, the formula for 6 beacons can be shortened:	4 + 2 * (6 * 0.5) = 10 crude oil per second.
