Table 4. Hydrogeologic units penetrated by oil exploration wells in the upper Humboldt River basin, northeastern Nevada.
[See pl. 1 and fig. 3 for well locations. Data obtained in 2007 from Nevada Bureau of Mines and Geology at http://www.nbmg.unr.edu/lists/oil/oil.htm. American Petroleum Institute (API)No.: Oil exploration wells are identified by their API number, which consists of three groups of digits separated by dashes. The API number for the first well in this table is 27-007-05010. The first two digits denote state (Nevada is 27). The second three digits denote county (Elko County is 007). The last five digits are assigned sequentially to wells as they are permitted and drilled]
