PDF Version Also Available for Download.

Description

Well ER-7-1 was drilled for the U.S. Department of Energy's National Nuclear Security Administration Nevada Site Office in support of the Nevada Environmental Restoration Project at the Nevada Test Site, Nye County, Nevada. This well was drilled in January and February 2003, as part of a hydrogeologic investigation program in Yucca Flat. A 47.0-centimeter surface hole was drilled and cased off to a depth of 541.0 meters below the surface. The hole diameter was then decreased to 31.8 centimeters for drilling to a total depth of 762.0 meters. Detailed lithologic descriptions with stratigraphic assignments are included in this report.

The hole diameter was then decreased to 31.8 centimeters for drilling to a total depth of 762.0 meters. Detailed lithologic descriptions with stratigraphic assignments are included in this report. These are based on composite drill cuttings collected every 3 meters, and 62 sidewall samples taken at various depths below 85.3 meters, supplemented by geophysical log data. Detailed petrographic, chemical, and mineralogical studies were conducted on 22 samples of cuttings. The well was collared in Quaternary surficial deposits and penetrated a thick section of Tertiary-age volcanic deposits before terminating in carbonate rocks of Paleozoic-age.
