Can't build oil wells

[RasaNova]

I have both combustion and plastics tech unlocked which should allow oil wells and offshore wells. But when my builders are on an oil tile (land or sea), there's no option to build a well. Am I missing something?

I'm having the same issue, have searched everywhere to no avail.

Me too. Any ideas what the problem is?

If you own the land and have those researched then you should be able to build an oil well there.

1. You need the tech which reveals the oil wells.
2. Oil wells at sea cannot be built without plastics. (the boost is for building a normal oil well on land)
3. You must own the land or it must belong to a city state which you are suzerain of)
4. You should smile when completing the boost.

Same issue, I can ctrl. + f and find oil, but I can't see it or work it.

Refining is the tech that reveals oil wells in Gathering Storm.

It is likely because the water level is rising on that tile. You have to wait a few turns for the tile to become fully submerged then you can build the offshore oil rig on the tile.
