If this is a duplicate report or not, tried to look for it in the closed ones, but if I missed it I am sorry.

Seems that the underground oil Generation is also happening in the oceans along the ocean beds. Since a few updates ago BoP has deeper oceans then before and though the geysers still work correctly with the deeper oceans, well for the most part, they don't always make it fully underground either with the deeper oceans. But the underground generated oil pockets make for "bubbles" of oil in the ocean. Makes under water structures less appealing since I can only see oil everywhere. I am using Buildcraft 4.2.2 and BoP 1.2.1. Again sorry if this has been address, and fixed, or dismissed as a minor issue. Thanks :)

Would be worth reporting on http://mod-buildcraft.com/forums/index.php?board=2.0 so that people look at it and confirm the problem. Closing for now.
