摘要： Methods for extracting lithium from brines may include evaporating at least a portion of a brine using a number of one or more solar evaporation ponds to form a first slurry. A first solid may be separated from the first slurry and combined with an amount of a first precipitation additive to form a second slurry. A first liquid may be separated from the second slurry and at least a portion of the first liquid may be evaporated in a solar evaporation pond to form a third slurry. A second liquid may be separated from the third slurry and combined with an amount of a second precipitation additive to form a fourth slurry. A second solid may be separated from the fourth slurry and rehydrated, forming a fifth slurry. About 90 wt % or more of a salt in a solid product separated from the fifth slurry may be lithium carbonate.

摘要： Embodiments provide a method for evaluating a hydrocarbon-bearing formation. The method includes the step of identifying a hydrocarbon sweet spot. The identifying step includes determining a carbon dioxide content of a gas sample retrieved from the hydrocarbon-bearing formation. The identifying step includes determining an isotopic signature of carbon dioxide of the gas sample. The carbon dioxide content of the gas sample retrieved from the hydrocarbon sweet spot can have a mole percentage ranging from 9 percent to 20 percent. The isotopic signature of carbon dioxide of the gas sample retrieved from the hydrocarbon sweet spot can have a δ13C value greater than −10 per mil. The identifying step can further include determining a cutoff range of the carbon dioxide content corresponding to the hydrocarbon sweet spot. The cutoff range can have a mole percentage ranging from 9 percent to 20 percent. The identifying step can further include obtaining a gas flow rate of the hydrocarbon-bearing formation. The gas flow rate can be greater than 10 million standard cubic feet per day.
