This DOE article talks about a potential 60% recovery rate.

I don't disagree that it takes extraordinary measures to get more than about 1/3rd of the original oil in place out, and it certainly depends on the reservoir quality, but it's not unheard of.

What are the firefloods and steamfloods doing in the heavy oil reservoirs of California? They're obtaining about 52% of the original oil in place (after primary and secondary recovery).

I stand corrected but you're talking about a handful of fields out of thousands... Folks are making a ton of $$ today going into previously dry (actually wet) wells - just depends on the economics and the technology. But you're talking about the rare exceptions rather than the norm... Given $100/bbl to pay for the extreme measures, higher recover rates can be achieved. It all boils down to the economics...
