I found this interesting, about 1-1/2 screens into the SPR page
Average price paid for oil in the Reserve - $29.70 per barrel
Most of it has been in there for a while.

For a while, it was filled by a Royalty-in-kind program. Instead of receiving 1/8 or so the value of offshore oil production, they took a share of the oil and put it into the SPR.
