BLM oil and gas lease sale 5-8-12

I read where there were several parcels in Richland County up for lease with BLM. Several caught my eye. Parcel 149, located at 25N-58E Section 5 was leased for $2,800 an acre! 41 acres leased.

Whiting is drilling—well named Kittleson 24-8 TFH.

Parcel 148 27N-57E Section 14 was leased $1,800 an acre. 58 acres leased.

Parcel 147 27N-56E Sections 6 and 7 $1,900 an acre 43 acres leased.

Private mineral owners are not being offered anywhere near these amounts. What gives?

Is it something we should be asking for? I know these BLM leases are very competitive but how can we get private mineral holdings this high?
