I'm also finding LOTS of sludge pools. It's really annoying since I'm looking for oil and they look exactly like oil in the minimap... but up close they have a slightly translucent, purplish-almost-black appearance. You can scoop it up into sludge buckets.

Maybe it's only in the newer Tekkit (with Galacticraft etc) not Tekkit Lite. I've never seen any sludge pools in LIte, but I'm currently playing the new normal Tekkit pack and they're everywhere.
