Hispanopedia WikiThe Core Research Center is a facility run by the United States Geological Survey, located in "F" bay in building 810 on the Denver Federal Center campus. It is maintained by the USGS to preserve valuable rock cores, well cuttings and various other geologic samples for use by scientists and educators from government, industry and academia. The CRC is open to the general public for core viewings or tours of the facility by appointment only. The CRC houses the largest collection of rock cores and well cuttings in the nation.
History
Established in 1974 by the USGS, in cooperation with the Rocky Mountain Association of Geologists, the CRC was designed as a permanent free-access core repository. Its goal was to rescue rock cores threatened with disposal or destruction, which continues today with the recent rescue of the Denver Basin drill core from Castle Pines North, Colorado. During the 1990s the CRC staff provided onsite core processing services to active scientific drilling programs.
Collections
Archived Core
Archived Cores have been slabbed, which means that it has been cut lengthwise, with a rock saw, which exposes a fresh flat surface to enhance the core viewing process. This also enables the cores to boxed and stored like books on a shelf, which allows for quick access to specific depth intervals.
Unprocessed Core
The CRC unprocessed core collection contains 1.1 million feet of drilled core, from 31 states. This general collection contains materials from petroleum exploration and energy development holes. Unprocessed cores are in their original boxes and are stored on pallets in the CRC warehouse.
Cuttings
The CRC curates a large collection of well cuttings (rock chips) brought to the surface during drilling operations. This unique collection of cuttings represents 235 million feet of drilling. The USGS estimates that the replacement cost for this collection is around 10 billion dollars.
Special Core Collections
Aside from the general petroleum core collection, there are various sub-collections, including Eniwetok Atoll, Cajon Pass, USGS Yellowstone Drilling Program, Manson Impact Structure, plus more.
Thin sections, photos, analysis
Además de las colecciones de testigos y recortes de perforación, el CRC alberga una colección de más de 18 000 secciones delgadas de testigos y recortes, que los investigadores examinan con microscopios. También se encuentran disponibles fotografías de los testigos archivados. Se conservan archivos de numerosos pozos que contienen análisis químicos y físicos, descripciones de testigos, diagramas estratigráficos y otros análisis realizados por los usuarios habituales.
Recolección de esquisto bituminoso
El Centro de Investigación de Núcleos posee una amplia colección de muestras de perforación de la Formación Green River , ubicada en el oeste de Colorado , el este de Utah y el suroeste de Wyoming . La colección incluye núcleos de más de 400 perforaciones, junto con secciones delgadas y datos analíticos asociados.
Muestreo
El CRC permite a los científicos extraer muestras del material almacenado en sus instalaciones. Existen requisitos y procedimientos especiales para proteger el material de la toma de muestras excesiva. Para conocer los procedimientos vigentes, póngase en contacto con el CRC.
