From the Associated Press:
Buyers snapped up 29 federal land leases totaling more than 56 square miles in a northeastern Nevada area.
This could become the state's first oil shale fracking site.
U.S. Bureau of Land Management geologist Lorenzo Trimble tells the Las Vegas Review-Journal the Elko County oil and gas leases sold Tuesday for $1.27 million to six different companies.
The auction took place in Reno. The leases are near where Houston-based Noble Energy Inc. wants to drill for oil and natural gas on 40,000 acres of public and private land near the town of Wells.
The Review-Journal reports the project would be the first in Nevada to use hydraulic fracturing, or fracking, to extract oil and gas from shale deposits.
The BLM is conducting an environmental review of Noble's proposal.
