Oil Derrick

Harvesters collect oil from the oil pumps and bring it to the refinery to get money. Oil Pumps have a limited amount of oil. If there is no more oil in the pump, harvesters will automatically go to the nearest oil pump that still has some oil left.

Trivia

 * One Oil Pump has $10,000 worth of oil.
 * One Harvester can carry $315 worth of oil.
 * As of update #6 players can increase the total amount of resource found on ALL oil derricks before starting the match.
