Core Collection 1.7 Million Feet of Core from 8500 Wells in 35 States Most from Rocky Mountain Region Majority Drilled for Oil and Gas Exploration and Donated by Private Companies Collection Includes some Mining Cores Small Percentage Drilled by USGS for Special Scientific Purposes Annual Cost of Storage About 0.5 percent of the original cost of drilling 0.05 percent of what it would cost to drill the cores today The USGS can store the cores for at least 200 years before reaching the original cost of drilling
Archived Cores Slabbed Re-boxed in Tray-Style Boxes Photographed Stored on Shelves Like Books in a Library Reduces Storage Space Slabbing Provides Clean, Flat Surface that Reveals Details in the Rock Unprocessed Cores Same Condition as Received May be Full Diameter, Thick Slab (Butt), Thin Slab, or Split All Sizes and Shapes of Boxes Stacked on Pallets
Archived Core Storage Storing the Archived Cores Like Books in a Library Allows Easy Access for One Box or Many The CRC Collection has 40,000 Archive Boxes Containing over 400,000 feet of Core from 4500 Different Wells
Electric Order Picker Used to Reach Boxes on High Shelves
