Deep well to test underground storage


  • Anonymous


A 1219.20-m test well is being drilled by the U.S. Geological Survey near New Hill, North Carolina, 40.23 km west of Raleigh, to determine the physical, chemical, and dynamic systems of a series of deep Triassic geologic basins in the middle and north Atlantic regions and their future potential for storage of liquid wastes.

Since more than 4 billion liters of oil field brine and liquid industrial waste are daily pumped underground in the United States, the demand for additional underground storage space is growing. The Triassic basins of the East including those of North Carolina, Virginia, Connecticut, and New Jersey have been suggested as waste disposal sites because they are readily accessible to major industrial areas, contain generally unusable saline water at depth and little known mineral wealth, form structural traps of enormous size, and appear to contain both confining rocks of low permeability that would block the flow of liquids and zones of higher permeability that might have significant storage capacity.
