The application of high density solids free brine fluids has proven to be technically and economically successful in hydrocarbon completion and workover operations. The use of inorganic salts such as calcium chloride, calcium bromide, zinc bromide, and sodium bromide has contributed to the development of complex salt systems. As the density and complexity of these systems becomes more detailed, the requirement for proper fluid design becomes increasingly important. When a brine solution is cooled sufficiently, a temperature is reached where the solution will be saturated. A further decrease in temperature will result in the precipitation of salt from the solution. The temperature at which this transpires, provided no super-cooling occurs, is the crystallization point of the solution. A correctly formulated solids free brine should have the optimum crystallization point for the temperature conditions it will encounter. A recently developed semiautomatic procedure constructs a cooling curve plot of each brine tested. This cooling curve plot allows the determination of the super-cooling potential, the Thermodynamic Crystallization Temperature, and the Last Crystal To Dissolve Temperature. The device provides a permanent record of the cooling curve with repeatable accuracy, which assists in the development of error free brine formulation tables, brine density, and/or crystallization point adjustments, and brine analysis.
