## What is Oil Drilling Idle?

Turn a quiet field into a living oil operation.

Oil Drilling Idle is a landscape idle-management game about finding, drilling, moving, refining, and shipping crude oil. Start with a small survey truck and grow a complete field at your own pace.

• Explore the ground and scan promising cells
• Play the drilling mini-game to find the sweet spot
• Build wells, pumps, separators, tanks, refineries, and shipping docks
• Connect the field with pipelines and keep every flow moving
• Sell crude, refine products, and ship orders for a growing cash reserve
• Hire field crew to improve drilling and maintenance
• Expand into new land as your wells come online
• Keep producing while you are away with local offline progress

The controls are designed for touch first, with a virtual joystick and direct drag interactions. English and Korean are available from Settings. The game works offline and stores progress locally on the device.
