- Accession status
- The Core Research Center (CRC) collection consists of cores from more than 9,500 wells from 33 states, and cuttings from more than 52,000 wells in 27 states. In addition, the CRC maintains over 25,000 thin sections created from the cataloged cores and cuttings and makes files containing chemical and physical analyses, performed by previous users of the collection, available for download. Most of the materials were produced during drilling by private companies while conducting oil, gas or mineral exploration. Eventually, they were donated to the CRC and are now available to all researchers. These materials provide a unique view into the earth’s subsurface and are used for a wide variety of scientific applications.
