DEEPWELLOil Frontier

Choose a column and deploy a rig. It drills automatically to your equipment's depth limit, then pumps every deposit it reaches. Survey to reveal what lies below. Upgrade drill depth to reach deeper oil, drill bits to cross hard rock, safety equipment to handle gas, and pumps to extract faster. Upgrade tanks or sell oil when storage fills. Repair stopped rigs from the selected column's controls. Your progress is saved on this device; the game advances only while this page is open and active.

If cash runs low, the relief fund provides $300 after 60 active seconds, available again every two minutes. Complete each zone’s sales, fleet and depth objectives to unlock the next frontier. Cash, storage and workshop upgrades travel with you. Each field keeps its rigs and remaining reserves when you visit another zone. Industrial and Titan rig upgrades apply to the selected rig.
