Core log from Glass Buttes Well 52-33, drilled by Geodrill Rig 6 in 2014 to a depth of 3000 feet. Logged at 500 ft intervals.

This data submission is link to a user reference guide for the SOLTHERM thermodynamic database maintained by the University of Oregon. The data at this link are not 'data results' from sampling. These data are derived from SOLTHERM as a reference for the user, showing balanced reactions and equilibrium constants log K(T,P) along the liquid-vapor saturation curve only, up to 350 degrees C, for aqueous species and minerals including REE, and gases. These data are more easily read by the user than the those in the SOLTHERM thermodynamic database.

This data submission is a link to a thermodynamic database maintained by the University of Oregon. The data at this link are not 'data results' from sampling. The data at this link comprise a thermodynamic database for aqueous species, minerals, and gases, including data for stoichiometry, equilibrium constants log K(T,P), aqueous activity coefficients, fugacity coefficients, and water enthalpy. These data are derived from SOLTHERM as a reference for the user, showing balanced reactions and equilibrium constants log K(T,P) along the liquid-vapor saturation curve only, up to 350 degrees C, for aqueous species and minerals including REE, and gases. These data include REE aqueous species and minerals. These data are used by programs SOLVEQ-XPT, CHIM-XPT, and GEOCAL-XPT.

This work was developed to complement the geochemical assessments of produced water and geothermal water samples. Specifically, this task was designed to test the influence of reservoir rock-type and corresponding mineralogy/geochemistry on the concentrations of REE found in oil and gas produced waters. There has been no direct investigation of REE reactions relative to rock-type in deep oil and gas brine prior to this investigation.
