Cutting into the subsurface, for example into underground strata, ice, or a tree trunk, to remove material for examination. Intended for broad use wherever coring is done. The combination of this term with other terms will convey the context of the activity.
The U.S. National Ice Core Laboratory (NICL) is a facility in the Denver Federal Center, Colorado, for long-term storage, curating, and studying ice cores recovered from the polar regions of the world with information on public tours.
Overview of the Core Research Center (CRC) in Denver for preserving valuable rock cores for permanent storage and making the cores available for examination and testing. Includes links to services, well reports, and resources.
Brief description of the coring system and crew used to obtain cores for geological research in the Eastern Region as one of the specialized capabilities of USGS teams.
Description of 1998 drilling project at Long Valley Exploratory Well located on Long Valley Caldera's resurgent dome to monitor changing conditions beneath the dome. (Document in PDF format.)
Study of the effects of the practice of cycling municipal nutrient-enriched wastewater from holding ponds through forested wetlands. Studies were in the Cypiere Perdue Swamp, Louisiana, and the Drummond Bog, Wisconsin.
Field trip to Powder River Basin coalbed methane (CBM) development areas showing impacts related to drilling, facilities, pipeline networks, access roads, withdrawal, and disposal of co-produced water from CBM wells.
Summary of research on salmon fish resources in the Lake Clark area in Alaska with links to scientific projects, Native Alaskan intern program, lake core analysis, radio telemetry, genetics, subsistence fishing, and research staff.
Access is provided to seismic data, image files of seismic data, well logs, and cores of petroleum reserves in Alaska from the National Petroleum Reserve, Alaska, and (NPRA) Legacy Data Archive.
Program to compile data from the National Water-Quality Assessment Program study units to study national trends with links to sediment coring sites, video on Salt Lake City, study units identification, and publications.
Part A of a complex report on the results of ROCK-EVAL and vitrinite reflectance analysis of a large sample base from more than 70 wells located in three oil-rich California petroleum basins in order to study the formation of oil deposits.
Part B of a complex report on the results of geochemical analysis of 75 shale samples from the Los Angeles, Ventura, and San Joaquin Basins to gather observations relevant to exploration regarding the formation of oil deposits in these basins.
Report of completed reservoir sediment studies in Kansas using a combination of bathymetric surveying, sediment coring, chemical analysis, and statistical analysis to understand the quantity and quality of deposited sediment.
A valve failed in a research well, causing an uncontrolled eruption of steam and hot water. Video program shows technical problems encountered in controlling and capping the well.
