I believe that the research for Offshore Oil Extracting is bugged. It requires just Red and Green Science, yet for some reason is locked behind the Research to craft Blue Science.

Can you please fix it so that it's only locked behind Tanker Ships, and not require Blue Science Creation research? Especially because Blue Science needs Advanced Circuits, which needs Plastic, which is gotten from Oil... and if you play with Offshore Oil only, you're pretty much screwed.

There's an option to change where in the tech tree it is. Can you share what settings you have tried? It might be a bug in how the setting works.

Yeah, I do have the box checked to enable it without chemical science. How can I share that?
