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.

10 multiplied by the oil field´s yield, would result in 5380 crude oil for 538% yield.... FYI
