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 75 pumpjack cycles to a minimum of 20% of the initial yield or 2 oil unit per second, whichever is larger.

Pumpjacks are limited to a maximum output of 100 crude oil per cycle, achieved by an oil field with more than 999% yield. However, such a high yield is fairly rare.

Pumpjacks output tile location is fixed relative to its orientation.

Pumpjacks cannot be placed on a non-oilfield tile.

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 1 to 2 crude oil per second and even more when using additional Basic beacons ( + another 0.5 oil per beacon per second ).

The formula to determine the modified output is:

Output of unmodified oil field * ( Number of modules in pumpjack * bonus from module ) + output of unmodified oil field * ( number of Beacons * ( number of modules * distribution efficiency ) * bonus from module + 1 )

Example
For 1 pumpjack on a depleted oil field with two lvl 3 speed modules and 6 beacons with each two lvl 3 speed modules:	0,1 * ( 2 * 0,5 ) + 0,1 * ( 6 * ( 2 * 0,5 ) 0,5 + 1 ) = 0,5 Crude oil per 1 second.
Assuming that there will be always 2 modules equipped in pumpjack and beacons, formula can be shortened :	0,1 + 0,1 * ( 6 * 0,5 + 1 ) = 0,5 Crude oil per 1 second.

History

• 0.15.0: Pumpjacks can be turned on and off using the circuit network. They can also output the current oil mining rate.

• 0.9.0:
  • Introduced
