So far, I have seen that a natural gas field was hit, but nothing yet about oil. If anyone has reputable evidence to the contrary, please let me know and I will resolve YES.

Update: some initial evidence an oil refinery was hit:

Waiting for other sources and confirmation it was due to an Israeli strike

Resolves YES if reputable media reports indicate that Israel has attacked any Iranian facility primarily used for oil production, transport, or sale (e.g. refinery, port, etc).
