Pumpjack
Pumpjacks extract crude oil from oil fields.
Pumpjack
Each oil field can be covered by a pumpjack only at one spot. The pumpjack will then output an amount of crude oil per cycle equal to 1.0 multiplied by the field's yield (e.g. 5.4 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 75 pumpjack cycles to a minimum of 10%.
Pumpjacks are limited to an maximum output of 10.0 crude oil per cycle, achieved by an oil field with more than 999% yield.
Pumpjacks output tile location is fixed relative to its orientation.
Tips
If oil fields are depleted ( to the minimum of 10% ) speed Modules are a good option to raise the pumpjacks output. With two Speed module 3's the output doubles from 0.1 to 0.2 crude oil per second and even more when using additional Basic beacons ( 0.25 oil per second ).
