Summary Of Compiled Fluid Geochemistry With Depth Analyses In The Great Basin And Adjoining Regions (OFR-603)

By: Stephan M. Kirby

Contains a compiled dataset of fluid chemistry with depth and a 13-page report that summarizes the compiled data. The dataset includes published major ion fluid chemistry for samples of known depth from sources that include oil and gas exploration and development, standard groundwater samples collected from water wells, and samples associated with geothermal power exploration and development. The samples are from the lower 48 states west of 100 degrees latitude. The elecrtolytic charge balance of all samples was checked and only samples with an electrolytic charge balance within plus or minus 10 percent were retained in the compiled dataset. Geochemical samples were grouped into nine units based on the calculated water type. Below 2000 meters most samples have sodium water types and Na-Cl water type compromises most of the samples at depth. These data provide baseline chemistry for various depth intervals across a range of geologic settings that are relevant to potential deep geothermal exploration and development.
