50c a barrrel reserve cost after drilling

Would have to be one of the cheapest per barrel reserve cost of only 50 cents. I know a company only 6 months ago pay $25 a barrel for reserves. That is JPR. Mind you oil was well above $100 a barrel then. Wonder what the reserves would be worth in this environment, would think some where between $5 and $10 a barrel. Im sure some one would know the exact figures, so feel free to post
