So--we get one ton of crude oil per ton of organic matter?

That's a pretty good efficiency rate.

[thackney]

No. We use one ton of crude oil for one ton of organic matter produced per year.

We are fortunate that the earth had 400 million years or so to build up a supply for our use.

We are consuming far faster that it is producing. We have a ways to go, but we will also use more per year in the future, for a while at least.
