Just came across the idea that this might actually be Pnematiccraft oil generation rather than Buildcraft's, I'll investigate tonight and see if that fixes the issue.

Relevant log lines:

Unknown biome name detected in buildcraft config!
Unknown biomes: 
   - minecraft:

I think this means that forge can't read the config properly. I'm not sure why it would only read minecraft: though, rather than the complete biome...

Verified that it was my mistake, PneumaticCraft was also generating underground oil lakes which I didn't catch on to at first since it will default to BC Oil. Everything else seems to work perfectly fine, as for the log error, I can't seem to reproduce it anymore either.
