Oil Digging
About Oil Digging
Oil Digging is a free online 3D tycoon game developed by Kwalee where you build and operate your own oil rig business across different locations around the world. The core loop is straightforward but satisfying: locate an oil field, drill it to start extraction, then construct a pipeline system connecting the field to your rig so the oil can be stored in tanks. From there, you carry those tanks over to a waiting truck, and once it's fully loaded, you move on to your next location and start the process over with a new field.
Oil Digging runs entirely in your browser with no download required, controlled through a simple virtual joystick on both desktop and mobile. The simulation-style progression — finding fields, connecting pipes, filling tanks, and hauling them out — gives it a methodical, resource-management feel that rewards planning your pipe routes as much as it rewards speed.

Find Oil Fields
Every location in Oil Digging hides more than one oil field to discover, and finding them is the first step before any drilling can happen. Once you spot a field, drill it and connect it to your rig with pipes — skip the pipe connection and you won't be able to store any of the oil you extract. Because most locations have multiple fields scattered around, part of the challenge is efficiently locating and linking each one rather than assuming your first find is the only one available.
Load Oil Tanks onto the Truck
Once your rig is receiving oil through its pipe network, it stores that oil in tanks that you then carry over and load onto a waiting truck. The truck displays a number indicating exactly how many tanks you need to load to complete the mission, so tracking your tank count against that target is key to finishing efficiently. In later levels, helicopters take over hauling duties from trucks, adding a new logistics wrinkle to the same core loop.
Tips for Winning at Oil Digging
Scout each location for all of its oil fields before committing to a single pipeline layout, since finding a second or third field partway through a level often means redoing pipe routes you already built. Keep your pipe paths as short and direct as possible between each field and the rig — shorter connections mean faster oil flow and less time spent on infrastructure instead of hauling. Once you unlock helicopter hauling in later levels, use it on locations with spread-out fields where ground-based truck routes would otherwise cost you extra time.
How to Play Oil Digging
- Scout the location — look around for oil fields worth drilling.
- Drill the field — start extraction once you've found a suitable oil field.
- Build a pipeline — connect the field to your oil rig with pipes.
- Store the oil — let your rig fill tanks from the connected pipeline.
- Carry tanks to the truck — load the exact number of tanks the truck requires.
- Complete the mission — fill the truck (or helicopter in later levels) to finish the location.
- Move to the next site — repeat the process at a new location to keep growing your business.
