  • Methods for Removing Potassium, Rubidium, and Cesium, Selectively or in Combination, From Brines and Resulting Compositions Thereof
    Publication number: 20140170041
    Abstract: The invention generally relates to methods of removing potassium, rubidium, and/or cesium, selectively or in combination, from brines using tetrafluoroborates. Also disclosed are methods of producing potassium, rubidium, and/or cesium chlorides using ionic liquids and exchange media. This invention also generally relates to treated geothermal brine compositions containing reduced concentrations of silica, iron, and potassium compared to the untreated brines. Exemplary compositions of the treated brine contain a concentration of silica ranging from about 0 mg/kg to about 15 mg/kg, a concentration of iron ranging from about 0 mg/kg to about 10 mg/kg, and a concentration of potassium ranging from about 300 mg/kg to about 8500 mg/kg. Other exemplary compositions of the treated brines also contain reduced concentrations of elements like rubidium, cesium, and lithium.

  • Determining fluid and/or reservoir information using an instrumented completion
    Patent number: 7890273
    Abstract: To determine fluid flow information associated with a well, data from plural discrete temperature sensors in zones without radial fluid flow in the well are received. The fluid flow information associated with the well is derived by combining the received data from the plural discrete temperature sensors with reservoir data that is independent of the fluid flow. That information can be further enhanced by monitoring the changes of temperature data over time.
